Jeep No Crank Diagnosis - No Start - Ignition Switch - Neutral Safety Switch 

This guy is awesome. My starter relay was still in the fuse block and I couldn't wiggle it loose enough to come out, so I wanted to see if all the wiggling was enough to make it startup. It started right up. So I would suggest that before you try to remove it and do the wire trick, you try wiggling the starter relay & make sure it's all the way in, then try to start it up again. It worked for me.

You probably wouldn't make it as a car salesman. Too honest. But thanks for being that way. We need more of that in this world. Good job Dave.

In my limited research about Jeeps, that is a pretty normal fault. I looked into the cost of those too, way expensive. I'm glad you left in the ignition switch section, you keep it real. I found an XJ in my area. :)

In the old days when starter motors were easy to get to, I had to remind myself to routinely test the signal wire at the motor while turning the key, before changing any parts when diagnosing a no crank no start. It kept me out of trouble by sending myself a necessary 'don't be stupid' warning if I was thinking about swapping the starter motor. If it didn't light then I'd look for a wiring diagram. These days, that approach doesn't work so well, with some starters underneath intake manifolds and often really hard to get to. Even so, as you nicely show, one can use the start relay to do it from a distance, making the assumption that wires between them are OK. That gives enough direction to find and test the bad part directly before tossing it. The other sneaky problem that can bite you is the bad engine ground, which is easy enough to find if you remember to think of it. In my experience, not always, ha ha ha.

At least we don't have the same guy that writes the instructions for putting together the cheap Chinese particle board furniture writing the vehicle repair manuals. At least not yet. Watching the video in the early morning here has just made my day. Rock on Dave!

Common jeep issue, nss. I just bought one like yours but black for 300 bucks because it wouldnt start. Cleaned and lubed the nss and it runs like a top. Great vid, I like real people saying it like it is.

You always do the right thing Dave. Good man. Love it

Fun video today! I loved the demos, and the way you explained your diagnostic techniques.

Dave, you are a good man. When I started watching the video, I suspected the safety switch. Had that problem with my buddies 96. Being a lock smith must have come in handy when you needed to swap out the ignition switch. Nice job and I’m sure the new owner appreciates your honesty. Considering selling my 65 Mustang and purchasing an old Jeep to work on. Would like something early 50s. I missed a cj3b from 53 a few years back. Thanks for the good content.

I'm learning

Glad she was happy with the purchase and that you did the right thing.

Not only are you a great mechanic and explained extremely well information

Thanks Dave for the tips.... I have a 4.0 in my Wrangler

good stuff thanks, this helped me fix the nephews 01 grand cherokee. that no start monster hidden down in the safety switch wiring

Great video. Thanks for doing the "right" thing for the next owner and feeling good about it.

Greetings from Lancashire England,Happy Christmas and New year to you and all your expanding family members.God bless you all

Awesome brother!

Dave!!!!! Glad to see you back!

Brilliantly entertaining as well as informative, thank you👍

Thanks for the regular videos again Dave!, and I think “ Gerry The Douche” writes a lot of manuals!!

You are a wonderful human being

Great video thanks

Great video Dave..

Right to the point!... You got another subscriber.

Dave you rock! This video has helped me so much. I am trying to diagnose this issue on my cherokee and i really can't tell if it's the NSS or Ignition Switch. My diagnostic tests are suggesting BOTH are bad. how can that be? I know my relay is good. I get continuity between 85 and 86. After hooking up pin 85 to battery ground and pin 86 to the battery positive, there is an audible click from the relay and i get continuity between 30 and 87.I tested every fuse in the PDC. I get continuity with all of them. I tested F19 in the junction block. Continuity there too. With the relay unplugged, hooked up pin 85 to the 85 cavity with a jumper cable. Hooked up pin 86 to the battery positive. No click. That suggests that the NSS is not providing a ground. With the relay unplugged, hooked up pin 85 to the battery ground, and pin 86 to the 86 cavity. With my helper turning the key to crank, the relay makes no click. Now this is suggesting that the ignition switch is not providing power.

Hey! Love you're videos! I have a yj with a rusted out floor in the front what would you do to fix that? I can't think of anything really

love it when you said "douche". Got similar issues, but won't start. I can wiggle the gear shifter and it will crank but not turn over.

Which leg on the starter relay is pin 85?

Where do you get the torx bolt tool?

i have a 2005 rubicon i have checked everything but the nutral safety switch i was unsure how ytou put that ground in to see if it turned over and start ?

Why didn't you try starting it in nuetral? Usually first thing I do if I have good voltage.

I lost it with "Jerry the douche". Subscribed

Hey, nothing wrong with having lug nuts torqued...........

Hello...I am happy to follow this video, however, I do have a question about my 94 jeep cherokee engine that is in my 1995 yj...I cannot crank at the key but can crank it with my brake pedal..it is an automatic 6...possibly my neutral start switch? Nobody seems to know what the heck is going on....😊

Omg you are very entertaining thank you for this video my boyfriend is haveing the same problem with his 96 jeep Cherokee and was wondering if you can send him a copy of that paper please and thank you

I’ve enjoyed these….

Did you name the FSM author after a certain persona you’ve met online? Lol, good tips on the starting troubles. Glad to hear the Jeep is in a good home. Probably better there than under the reign of employees.

Put a relay on ignition 12v +to take heat off ignition switch to avoid melting when using ac /heater. Also fixes the blower switch melting issue in dash

Dave, it's easier to take apart the NSS and clean the contacts, than suffer highway robbery. I've done about 4 NSS's on XJ''s. Great video.

Where is the location of the horn relay

Randy Quaid of Auto Repair..hilarious. .thanks for your help.

Hey man I live in joelton of nashville is there anyway I could get some more info I did the same thing think it was the ignition switch and then I seen your video so I went ahead and took it off is there any way I can bypass it until I can buy one

Confession: When Michjgan Weather is ... unpleasant.... I’d rather just watch Dave work on his Jeep while I just drink coffee.

A lot of Gerrys in UK Dave ,lol say it as it is mate

DAVE. What if it's turning over, but not cranking all the way. Its firing up, but not turning all time way over.😊

Lmao thanks I needed good. Video

Do you also play cousin Eddie in the National Lampoon movies? 😜

You’re so fucking funny I have thoroughly enjoyed this video

Man where are u located please come to my way and help me with my 99 jeep cherokee sport I have alot of starting issues it was starting nd now it won't it has long cranks even when I let go of key stops when I take it out but even before that started its been back and forth on starting nd not also had issue with driving sometimes but I think that's is fixed with new exhaust I put on but I can't test it long enough since it won't start now

This makes me want to sell my jeep as soon as I get it running lol

😂 good one

Your heads at " well lets load up the parts cannon"

Dude is funny

Woo..Someone gets a little cranky when they misdiagnose the problem...lol...Good job on doing the right thing by replacing that water pump....👍👍👍By the way,why was the douche bag named Jerry? lol....

Lmao...Hi I'm Jerry.. I mean Jessi. 👋

Their should be a Disney movie about how cars get pissed when you decide to sell them and slowly self destruct part by part.

This is definitely a human experience

Jerry is a lawyer who got paid per word written.

Whenever you said Jerry the douche wrote this I had to hit subscribe 😂

You

i really like your videos. i want to send you Motorcycl Speedometer for free and you leave me nice feedback on amazon.is that ok for you?hope for your reply!

Hahahaha

Oh, you mean someone that does things the right way? Like a person that would thoroughly troubleshoot a problem before buying parts they don't need.

Being thorough doesn’t make you a douche. Trying to take short cuts all the time may work more often than not for you but when it doesn’t, it will be the “douches” who will figure it out.

jrtty the douchebag aint got nothing on you.....20 mins of jibberish and no intel

Great video thanks
