Help! My ATV Won’t Start! What to Check First | Partzilla.com 

He is a very good mechanic! I have used several of his videos from diagnosis of small issues to full top end rebuilds.

This guy has got me out of so many binds

Thank you for going through the whole scenario, most people would just stop at the fuse and say there ya go. Good video!

Had this happen a few years ago on a 2001 Honda Rancher that I bought new. It had been starting perfectly I always had a battery maintainer hooked to it since I bought it new. One day I tried to start it, nothing it was dead no spark,battery good,etc. I worked on it off and on for a week with no luck. Finally I found the culprit,it was a main frame ground wire rear right tire that was corroded and not making good ground contact. I cleaned that up,put a dab of grease on the connections and it fired right up and ran fine until the day I sold it 3 or 4 years later. My Rancher had never seen any mud or water, so yes just the humidity in the air over time can cause connections to surface rust up and cause you a headache. Also even if a battery is showing good voltage I also would have it load tested, that can also be the culprit at times.

Thanks John for your fantastic repair video's. Keep them coming !

John, Could the control motor Assembly be an additional cause of my ATV not starting? (2007 Honda TRX500FE ) .

Thank you partzilla for the great tips.

thanks for the vid! it helped me out,..straight and to the point!

Thanks for the advice. Cleaned the carburetor and starts easily and runs great. 👍👍

Excellent video! I don’t know who down votes these but ignore them and keep making awesome videos

very knowledgeable about the parts an where they are located. very straightforward. Thanks

Thanks. Keep the vids coming. Just bought 400ex Honda.

Great video, thanks! Do you have any ideas why a Honda Fourtrax might turn over, but not catch and start? Lights are on, battery is good, engine turns but will not go. Thank you. (fuel is getting to the carby, and tried recharging battery as well as jump starting it, but it just turns over).

My started yesterday with startcables from a tractor but know it doesnt even click

Thanks for the reply...was turning over and everything seemed fine...i changed out starter clutch and it fixed the starting issue....guess it was worn and wouldn't let the starter spin fast enough to make machine fire off electric starter

This completely awnsered my question thanks.

Just because the solenoid clicks doesn't mean the starter is bad I have seen lots of solenoid click and the contacts inside be burnt up so always check your starter to your positive to see if your starter still turns over.

thank you. you saved me from having 2 very sad kids.

Love your videos I’m learning so much

Ok kool thanks for the info I will check it and keep you posted thanks for getting back to me .

I'm not getting spark on my 1997 Honda Foreman 400 I replaced the stator, pulse coil,ignition switch,ignition coil,cdi box,regulator,spark plug,battery what else could be wrong I hope its not the timmimg when I'm at top dead center the piston comes to the top of the cylinder when T Mark is shown in timmimg hole I'm getting signal from the stator to the pulse coil into the ICM

My 03 honda rancher ..the neutral lights or none of odo lights are working and will not turn over unless I jump solenoid

If you got a Kawasaki Bayou 300 like me all of this troubleshooting done above I had done but still missing out on something ! My quad would turn on with all the lights and everything, and when i pressed the starter button it would start 1 times out of 10 ! And when it got really cold out it would not start at all except with the pull cord... Then after some digging on the Bayou microfiche I found there was a cylinder relay under the quad just above the muffler hanging on the ATV... I got that replaced and BAM my ATV starts like a new one now !

I have a 03 recon Trx 250 and I have no issue starting and running while being pulled but will not crank when tried by the cable or the button and then there no throttle response because it also shuts off in neutral anyway you could guid me through awesome vids pretty direct and helpful

My Atv has spark ,fuel , cranks and won’t strat

Oh I found this out my self, if the motor turns over and doesn’t start check the wire that goes down below your shifter and make sure it’s connected, I’ve wasted over 300$ on battery and starters, but It was a little wire disconnected

Great video !! What if you have a 2001 Yamaha kodiak the neutral light indicator light and a new push button ignition switch and the only time the headlights and neutral light indication work is when you jump the solenoid. Starter works and it runs but only by jumping

That was a good video I just traded my sled for one and the fuses u showed that was a promblum when I change it I hop that was the issue

I have a yamaha wolverine 350 4x4 hit the start switch but I'm getting no fire to the spark plug I changed the ignition coil and the solenoid. still not getting fire to the spark

Thanks for the helpful video. We have a 2004 330cc 4X4 Outlander. It turns over fine, but doesn't start. We cannot get a spark from the spark plug, so does that mean there is problem with the electronic ignition? Probably have to replace whole unit? Craig

That was a great video sir. My 4wheeler is a 2013 Honda Rancher 420 and I have no dash lights when I turn the ignition. Does this model have a hidden fuse also? Thank you

really handy vid, my quad is got one click when I go to start, (like a thump) battery life is good and new solenoid I’ve put on. Will this make it the starter motor that’s wrong or a earth wire?

Thanks. very helpful.

by the way excellent informative videos keep making them

i am having an issue with my 2007 yamaha vmax . my bike shuts off when i close the choke. do you have any videos on what the problem might be? this video was extremely helpful to me for get my bike started and easy to understand. thank you.

You guys do good work

I have replaced starter solenoids that have functioning relay coils but the high current contacts are burned. You can easily test the starter at this point by jumping battery positive to the starter lead post of the starter solenoid. Also a test light to check if voltage is making it from the start button to the relay coil of the start solenoid would be advisable. Initial steps for checking battery and fuse spot on.

05 Yamaha Bruin 350 2x4 was running beautiful after a day of riding turned it off to get the trailer ready to load and tried to start the bike. Starter and everything work but lost spark. New plug checked all fuses and still no spark where should I go from her? Thanks love you channel and partzilla

exellent video !!

I would like to know if you're glosses are safety glasses and where can I get them to buy if they are

great vid thank you but...... i replace the fuse in my 2004 250ex and it keeps blown fuses it will stay running but eat up the fuses?

Hi, great video, thanks, helped a lot but I have tested solenoid and that seems fine but when i turn the key the solenoid vibrates but the engine wont turn over, tested the starter and that seemed ok, any suggestions

very nice video very helpful. my question is my ATV will crank but it wont start I have no spark to spark plug n flooding my ATV can you suggest where to start checking tks.

Partzilla, everything is good my fourwheeler is turning over and it has spark but it just will no crank up, it acts like its trying but will not, could it be my cdi box?

Hey how you doing I got a quick question for ya. When I do a cold start I have to give my honda TRX 400ex gas a few times to get it going I already checked the carburetor it wasn't dirty except for the jets so I had that clean out and it still doing the same but when I give it gas I hear a lil tic when it first starts up. Do u think a need a new accelerations kit

Question. Replaced all electrical components on Honda four track 300 and still get no spark. I’m at a loss. Any ideas wasn’t Honda certified shop for four months and they couldn’t figure it out.

I love your vids im learning tons from your exp ty very much ...i need some info on the proper way to re install the shifter and gears with the forks im about to pull my 04 trx 400ex and rebuild it the case is cracked real bad so im doing a total rebuild can u pls do a vid on the proper setup for tour gears and forks ty

Hey guys so I got 03trx400ex and other day I took it to ride and I loads my truck and everything worked truned on and ride it for a bit and once I got place i was going ride didn’t want trun on anymore ? It would trun over battery was good had gas not sure what’s going on ?

Thanks for the video!.....I have an 08 Can-Am Outlander 500 XT. It has had intermittent issues with what made me think the battery was dead. Key on, no lights but hear fuel pump...won't crank over. Jumping solenoid turns the starter over but even with key on, it won't start and again the dash lights, headlights, etc don't come on and it won't crank over unless jumping solenoid and even then it won't start, just cranks over? I plan on removing wires, cleaning terminals up and maybe putting a lil grease on terminals. I'm not getting acc voltage to the solenoid. Hand park brake is on, I pressed the pedal brake, kill switch is in on position, and tried in Park & Neutral with same result. Any info would GREATLY be helpful. Thanks in advance.

I have a 98 350 warrior just rebuilt it and plugged all right wires in but I told my dad that the clutches have slots and supposed to line up and now I have no neutral light and the starter clicks without pulling in the clutch while starting it so what is my problem

I have a Trx350fm that does not indicate neutral. There is power to the system. The starter battery and solenoid are good. I need your professional guidance.

I got my wife a 2008 trx400ex. split the case fixed 2nd gear. put it all back together. well we went riding this weekend. was fine but clutch and yes it was brand new started slipping and quad just stopped pulling. got it back to camp next morning wake up go to crank it crunk fine tried to just load it on trailer motor died won't start at all doesn't even turn over. would the clutch going out make it do nothing. i watched your vids and done alot if the work myself so thanks any advice would be a great help

Sir ! I have a xr400 and my resistance of black+red and brown wires is 600 ohms, I have spark but my stator is repare so, do you know if that number is good or my cdi is in danger? I have been lloking for the info everywhere and I cant find the number of ohms that this coils must have, thanks for the help

I've got a 1988 300 4x4 fourtrax, the fuses are good an have neutral light, the kick start never turned the engine over since I bought the machine second hand. So just used the starter, but now all of a sudden I can't turn the engine over, the machine also won't click into gear so there's no way to tow it to see if the engine will turn over. Some advice would be greatly appreciated.

Hi , I have an atv 150 cc . I have a issue with starting. In this morning, it was running for few meters and after stop to run in the moment when I tried to accelerate it I tried to restart it but it wasn't happening.. Particularly, I saw that when I tried to restart,the lights are off... I checked the battery,and the carburettor and it's ok.. Any advice? Thank you very much

Noooo, i buy a atv so now i have to watch ur videos xD

I have a 2007 trx450er and I landed hard on a MX track. It turns over but will not start. Checked the spark plug and the wiring. Any other ideas? Thank you!

Hey John. My problem is with a 2000 Honda Foreman 450 ES. It started just fine yesterday. Now today the electronic start button, both headlight switches, and the kill switch don’t work. However, the electronic shifter buttons work just fine. I tested the solenoid and the starter. They both work fine. No clicking when I hit the start button. No noise at all. The green light does come on when I turn the key. I checked the fuses, none of them look blown. Maybe I didn’t see one? I only saw six total. Four inside of the rectangular box, and 2 separate 30 amp fuses by themselves. Any help you could give me would be greatly appreciated. Thank you.

My 97 yamaha turns over but doesn't got a new carburetor, adjusted it 9 way to sunday but couldn't get the spudder out so i took it back off to make sure the floats were acting right only to find the air flow needle tip had broke and was stuck in the hole.so i got it out and put the old one back in and a little shorter but had a chance to see if it does because it won't fire just turn over. Oh and the plug got stripped going back in now it takes a 14/1.25 instead of the original 12/1.25 would this ccx ause it to not fire? Thank for your help

how do you test a ecu for a 05 polaris 330 trailboss? have no power at the controls and lights, i checked continuity looking for broken wires, tested solenoid, check connectors checked grounds, it all start right after i jump started it with my jeep

any recommended videos for troubleshooting a NO SPARK condition? I have a green neutral light, the machine turns over but when checking spark plug, no spark. How do i walk up the circuit & check the coil, CDI & on up-circuit ?

Do these have a field cut off button or fuser switch to shut the field house in case some happens like an accident or tipped over

Buddy got a cheap Chinese 4 wheeler for his 6 year old son to ride. It won’t start. Lights turn on and battery seems fine. I will check the starter next and any fuses. Hope it works.

i have a 1995 kawasaki kef300 lakota. check the solenoid as u did and it cranked over hooked the solenoid back up but four wheeler wouldnt start my four wheeler also has pull start used it and it started why

ok I have a question I have a 2004 kfx400 was running fine until I redid all the fluids and not it tries to start (turns over) but wont actually start

I have a 2009 honda rincon 680 fuel injected, will not start, replaced everything, fuel pump, fuel relay, air filter, spark plug. when i replaced the fuel pump assembly ran for a little while and then stopped again, would star and run poorly intermittantly, I have even drained and put fresh fuel in it. If i take the air filter of and use a little starting fluid it runs perfectly. I'm thinking I may have gotten a defective fuel pump, I have a new fuel pump rebuild kit coming today, going to give that a try. What are your thoughts on this matter? Tony Kucherry

So I’ve had an 04 Honda 400ex for 8 months go riding all the time and last weekend I started it up was letting it idle and it cut off and I tried to turn it back on and it made a click and lost all power. I can’t jump solenoids nothing happens when I do, I can only bump start it. Is the issue the ground? If so where is the ground located?

I have a 07 400ex that needs starter bushes will the 99-04 brush kit work they look the same as mine

I have a 2004 yamaha raptor 660r and I'm having a problem starting it. I have a brand new battery for it. but when I go to start it the solenoid only buzzes, not just a click and my oil light comes on. I was also riding it and when I slowed down it shut off on it's own too. I just put a new spark plug it in too and I'm not sure what to do to fix it or what I need to replace on it. Can you help me or give me suggestions on what I should do please?

Hey partzilla.com,I've been working on a buddies 93 KLF 300. I put a new battery and new selenoid, a new starter relay. Cleaned all the wires and put a new fuse in, although the neutral light won't turn on nor will the reverse light come on. (I thought it was simply the bulbs out)If I put some juice to the starter with my jumper box it turns over. But I don't hear a click from my selenoid when I push the start button. I got the ATV to run finally with a pull start. I was wondering; could it be the neutral safety switch that wouldn't allow the push button to operate? Thanks in advance for your help.

05 Honda 400 ex. Fuses are good, battery is good. New ignition switch. Can jump over at solenoid,but won't start up. Not getting power to show neutral light is on. Lights and nothing else will illuminate

I have a 450r and I have the first problem with the fuse but I can’t seem to find it. Do you know where the fuse he showed is?

Hi I just replaced the spark plug on my 2000 400ex and it started right up I rode it around the block then the battery disconnected and after that it cranked up but didn’t start do you know what might be the problem, thanks

Hi I have a 99 banshee, and sometimes it runs fast as hell and other times it just kinda seems slower, the carbs are clean, and everyone else is clean, it usually starts 2-3 kicks.

ok I have a question I have a 2004 kfx400 was running fine until I redid all the fluids and now it tries to start ( turns over ) but won't actually start

How’s it mate I have a Honda trx 300 ex 1995 model I’ve done what this vid has said an still no power going through or not turning over I blow the fuse when I connected solenoid straight to battery change fuse an now nothing so I’ve replaced the solenoid now I’m back to square 1 any other ideas

I have an 06 Yamaha bruin 350 that I bought like 8 year ago, I've put it through some tough stuff in deep water,it's fully snorkeld and dialectric greased but the cdi box shorts out very quickly and I replace it about every 3 to 8 months with the fuses and sometimes it won't crank up, and it makes a short tap or click in the solenoid and sometimes buzzes.What should I do?Thanks

Hi,I have a 08cat650hi quad,never a problem. Drove in ,shut it off, and later,won't crank or start.dash lights,lites work .it acts as if it's in gear! If I jump solenoid,it won't fire! Bad neutral safety switch? Thank youk

I have a 1988 Honda Fourtrax 300 the headlights nor the taillight work is it powered with an inline fuse somewhere? I was thinking it could be a blown fuse could that be possible?

My 2003 Rancher starts and runs fine for a few minutes, then it acts as if I hit the kill switch. I have replace the carb, drained and replaced the fuel. Any suggestions on what to test next?

Thanks for the quick response

I have a question I have a Honda 400ex and when you start it run but then shut off . if you keep on gas it ideals fine but once let off it stalls

Have a 92 Polaris trail boss 350 4x4 and I was trying to find the spark plug?

I have a 06 trx400ex , redid top end valves etc, left the same piston and rings (had no play) timing is right everything seems good, I crank it and still sounds out of compression and won’t start, please help!

My Honda Ranchers starter has a slow crank. I wouldn’t diagnose it as a dead battery, the neutral like isn’t dim or off at all, and I’ve ran it multiple times this previous week with it slowly cranking and then firing right up, i let it sit a few days because I couldn’t get it out of the garage these past couple days, now the starter is still slow but it won’t fire, I have no clue what the problem is, any help?

I have a 1990 fourtrax 300 and have no lights in dash. Head lights and brake light work but starter does nothing. I have already replaced the cdi, starter solenoid and the ignition coil. What else should i be looking at?

okay I just bought a 2002 Honda 400EX and it started raining and I put it away overnight whentowork came home started at it rain and then head to gas it died but I think I had the choke on but now I can't get it to run it wants to fire and I bought carburetor and a couple other thingsif you have any ideas for me. I mean true mad at me this is my first 400 e x I rebuilt 250R so I mean I have experience but not experienced with a 400EX. And another thing would it be just easier to buy a whole new harness? one more question on the left side of the motor there's a war going down till like almost the bottom of it what is that wire is that would like the oil temperature or something like that, hope you can answer soon thank you so much

I have power past the solenoid. What do I check after that? Bad short some where. Cant crank by the key. Brand new ignition. Help!!!

Hey! Having trouble with my 2007 Honda trx 250ex not starting. Making a clicking noise but no turn over, any ideas?

Thank you your video helped alot

So what’s left to check if mines dose all of that, I’m not getting any spark, but the rest of my quad works fine

mine 2000 400ex does the same thing. I am pretty sure I flooded the carburetor though. any signs that would know you flooded the carburetor?

This is an excellent video. For my own future reference: 1. Check the battery. 2. This little junction right here. Fuses. 3. Jump the solenoid directly from the battery. 4. You probably have a bad starter.

If the Solenoid clicks and starter doesnt make any noise. occasionally I hear the starter make a weak turn, but nothing consistent, mainly just a click from solenoid. does this mean starter is bad? I replaced battery and checked that fuse and all is good.

I have a yamaha grizzly 80 cc 2005. We don't have any spark and we have replaced the CDI box, ignition coil, and have checked the kill switch and it's good. There is power going to the coil but still no spark. Do you have any other suggestions to what may be wrong?

I have a 400 kal atv that won't start , natural light works, starters good ,solenoid clicks. won't turn over .tried bypassing solenoid with hot wire from solenoid to starter it didn't engage starter so could the solenoid still be bad?

thank you!

Mr John, My 1999 honda 400ex wont start. I think it has to do with electrical, bc no green light, no nothin. I got a bunch of wires not hooked up to anything and wandering if it would be better getting a new wiring harness and starting from scratch. Any input would help tremendously. Thanks Stimpy willis
