OZ, YOU ARE BORN TO BE A DIAGNOSTIC TECH. I AM RETIRED 75 YEARS OLD TECH. SPENT 15 YEARS WORKING FOR LARGEST AUTHORIZED FANCY DEALERS DUE TO MY QUALIFICATIONS AND LICENSES. EVENUALLY, I DID THE FIRING AND WORKED FOR MYSELF LIKE YOU ARE DOING FOR 21 YEARS; YOU ARE A GENIOUS GOOD LUCK.
Thanks for the kind words sam. Please feel free to watch my camaro series video. That was a fun video to film. Car ran for 10 min without any fuel delivery
I'd still test for leaky injectors... Check the upstream fuel trim then run a lead down test if it's rich. If the injectors are good check for gas leaks and then check the check valve on the fuel pump.
@@OzMechanics I thought I did, and I recall you mentioning replacing the fuel pump, but I didn't realize you got that far. Still it's hard to think how low fuel pressure at start up flooded the cylinders. It should have kicked over when it got fuel... in a rational world at least... but that was a Chrysler products, as I recall, so I guess, all bets are off.
What flooded the engine was the temperature sensor was reading too low which caused the computer to dump more fuel and saturated the cylinder. In the beginning of the video I talked about how the vehicle was stumbling at initial start up. You can rewatch. That’s the cylinder running too rich. So when ever the vehicle is was shut off and was ready for restart it would have a hard time starting because of all the fuel in the cylinder caused by that faulty sensor. Does that help out ?
19:03 .. my dodge has done this off & on for a few yrs. Recently been doing it more frequently. In video u stated u were going to replace the fuel pump. *Is that what you ended up doing* 🤔
@@my_flippin_journey It's too easy to assume that the same symptoms with a similar car should be caused by the same thing. While this was somewhat true back in the day when cars had fewer things to go wrong and there were fewer kinds of cars around that all broke more or less the same way, it isn't true today. Find yourself a good diagnostic mechanic... not a parts replacer and have your car tested thoroughly and then it will get fixed right the first time.

Good video Oz! thanks for taking the time to share this diag with us, new Sub here! Was cool meeting you guys at ASTE! keep em coming and we will see when can meet again! 👍👍
I have a 2011 dodge nitro heat the starts cold every time, but after it is warmed up 20 25 min. If I turn it off and try and start after a few minutes it tries to start, sputters but does not turn over. If I wait a bit and try again it starts up with no problem. Very confused. It had a new fuel pump put in just a few days ago. Any help is appreciated.
Oz, don’t you think it may also have a fuel injector leak as well due to the drop in pressure. Why else would that spark plug covered in gas? It may have more than one problem you know that’s how dodge does it 😂.
The check valve was damaged in the end of the video I show by priming the vehicle it turns on perfectly. If it was a leaky injector it would not turn on when priming it.
@@OzMechanics interesting, that’s what makes you the teacher and I the student. I would’ve thought even though it were only one it could still start due to a leak on a fuel injector. Keep up the great work, your videos keep getting better!!
Thanks for the tip, got the same problem after engine heated up it wont start sometimes, I always had to wait till all lights come off another question, any idea why my brake lights (except the third one) not working bulbs are ok, I already changed the brake light switch
Have to watch those substitute values. Sometimes there will be a voltage PID to reference off of to verify. In this case the temp gauge was your clue. Could have also checked voltage reading at the engine computer. Glad you figured it all out in the end.
Man I actually recorded a lot of the scan data and more test. But when I went to edit I found out I never pressed play. I had to Frankenstein the video to get it good
My Nitro same year, has the same “lightning bolt” symbol on and it just cranks. I will try what you just did, my only concern is that mine doesn’t turn on at all, so I’m wondering if it just has to do with sparks plug. Great video tho!
Technically you have two different problems. Ect sensor do cause engine not start and additional to fuel pump. You should charge two different problems to diagnose. Just saying but good job though
I charge hourly when it comes to diag. I verified the initial complaint of not starting after a drive and after that I explained the other issue. He was just happy we could take out after stopping somewhere. Thanks for watching
OZ, you are AWESOME brother do like ur approach so is this issue with bad temperature sensor with all make or only dodge/Chrysler cars that the pcm will do that and make the car not to start thankyou and cheeeeers.
On the video I sent explained it was the sensor that was causing the ecm to ive fuel the system. That’s why the precios shop changed the spark plug because they were over fueled. The second issue was the fuel pump. The fuel pump is supposed to hold fuel pressure but the check valve went bad and didn’t allow that. So on the test I performed when I cycled the key, it allowed the fuel pump to prime the vehicle so it could start right away after cycling the key a couple of times. Thanks for watching! Hope this helped
The temp sensor was causing the over fueling which caused the engine to not turn on after driving it. And after fixing the temp sensor, I noticed that it had another issue with the fuel pump not holding pressure after shutting it off. Fuel pumps have a check valve in them that hold pressure
@@OzMechanics great. thanks for the response. Many of us with this vehicle never suspect fuel pump because the pump works flawlessly when the car is running.
Hey Oz, sorry brother but I really wanted to give you a big thumbs up but I just couldn't do it. There isn't a big thumbs up button anywhere that I could see so I had to give you the regular thumbs up!😅 But here's a little bonus for you! 👍🏼👍🏼👌🏼
@@MarketingCoachKen I didn't change fuel pump yet and it seems to clear itself up.. I need to change the oil pressure switch but having a hard time getting it out.
@@Mountainmanfishing OK. I have NOT seen many people solve this problem with a fuel pump. Otherwise you would see everywhere that this was a simple fix. I also recently did the oil pressure switch. When driving any time I stop at a traffic light or stop sign, the oil light came on. Simple fix. The new sensor is a very tight fit to install and I bought it from the Dodge Dealer. The first challenge is getting the threads of the new sensor lined up to start screwing it into the engine. After you finally get the perfect angle for the first few turns, it starts going in but there's quite a bit of resistance. You CAN"T finger tighten the oil sensor. I had to use a short 1/2" ratchet and use plenty of leverage with my weight to slowly turn until I could tell that most of the threads were in the engine. I do have long arms and I was able to do the repair by removing the headlights and grille assembly to reach the sensor. This sensor must be slightly larger than the hole it goes in and it uses like a plumbers tape to seal and make sure oil won't leak. It's difficult to screw in because it's a poor design. The only thing you don't want to do is keep turning the wrench after the sensor has already been screwed in all the way. This is the main thing to keep track of. Otherwise straight forward, and the how to video is here on YT.
@@MarketingCoachKen Yeah I tired to get the red little clip off an im having issues with getting it out so I can take the wires off of it. I took the coolant tank and battery out whenever I did oil change and tired then. mine is a 2007 and the oil filter is a PITA. I have been trying to find out what the whining rumbling noise is whenever I accelerate it sounds like Transmission but it shifts fine and I changed Filter and gasket in it. Replaced the front prop drive shaft that wasn't it. It also sounds like it can be coming from rear end I changed oil in it and everything seemed fine and sometimes it sounds like it's coming from front axel. It has been a PITA got a new fuel pump too. I'm having a mechanic do the CV Axels,Fuel Pump and Rack we traded some stuff I had for some work. I'm disabled so it's harder for me to work on. oh and I had to put new rotors brakes and a caliper on the back. I bought a new rack and pinion because it's leaking like crazy as well as CV Axels and Fuel pump.
@@Mountainmanfishing Sounds good. Yes I gain access to the oil filter by removing my headlight assembly. Did you get that fuel pump installed and are you still having any problems starting the car when the engine is warmed up like this video is about? Meaning did the new fuel pump fix this problem?
The trick I used In the end of the video to rule out a leaky injector was to put the key on the on position for a couple of seconds to prime the engine and then it would turn on good afterwards. Rewatch the end I explain that
hello, I JUS got dun watch'n ur video I'm hav'n that sme issue I was told it was mi transmission bi aamco in Prospect park got a brand new still hav'n the issue I was told it is mi fuel ⛽ pump ⛽️ jus got the new 1 yesterday, gnna get that put on, nw auto 🚘 zone is sy'n it'z a fuel ⛽ issue thy sad 2 tri sun starting fluid gonna tri that 2morrow, I dn't hav the cooling needle issue, but I du hav the start'n issue, culd u PLEZ help mi u did mre in ur video thn ANY shop I've tlk 2 about this…
I would think that on a newer vehicle like a 2009 that it would look at ambient temp sensor, air temp sensor as well and if it saw the coolant temp sensor it would go into open loop. I would understand on an older vehicle acting up just on coolant temp sensor because it’s more of a primitive
@@OzMechanics right😏i did my ECT sensor on my 00' Buick a while back, car wouldn't idle or barley start. If that PCM don't know the temperature everything goes Whicky Wacky🥴
INTELLECTUAL Oz Mechanics My teacher Tutorial great video brilliant thank you very much helpful information video Take care and have a great Evening INTELLECTUAL Oz Mechanics From Nick Ayivor from London England UK 🇬🇧
Real nice work brother I have seen this issue before with the temp sensor not allowing the car to start I'm starting to think it's a Dodge thing... Awesome work thank you for sharing....
I had the same issue with my father's 2009 nitro. I changed the ect and replaced all 4 oxygen sensors then performed a throttle relearn on it and it's been doing fine for a couple months now
