Car just quits

pudi · #1 01-27-2007, 01:04 PM

Hi everyone!
I started having problems with my vision again. This time car just quits during drive. If I try to start it up again it won't work. If I leave the car for an hour or so it will start up normally but wont be running for long. After 5 minutes or so it dies again. Any ideas? Thanx in advance to everyone!

UPDATE: Car quits when engine tempearture rises to normal. If I try to start it up for the first time after it quits it starts for about 2 seconds and then it quits. On another try it wont start not even for 2 sec. If I leave it to cool down then it will start again and work normaly until the temperature rises... any ideas?

one thought, just for a stab at it. Disconnect the wiring harness at your water temperature sensor. Try it at cold start condition, say when you get up in the morning. Unplug the harness the night before, and then try to start it in the a.m. Drive it around town, unplugged, until you think the engine is at operating temp. See what happens, re if the car dies again.

I'm not positive, but I recall the temp. sensor would trigger a "hot-run" condition if faulty or starting to go, and cause the car to stop running until the engine cooled a bit. At least you would eliminate one possible cause if it doesn't change anything unplugged.

Don't forget to plug the harness back onto the sensor after/or if you try this.

Thanks for helping! Well, here's what I have done. I disconnected the coolant sensor when the car was cold. Then I started the car and the fans began blowing immidietly and "check enine" light went on. I tried to drive but throttle almost didn't respond and I smelled gasoline. I gues the mixture wasn't right becouse of the unplugged sensor. So I turned the car off and connected the sensor back on. Then I started the car again and leave it for about 10min to heat up. After 10 mins, when the car was at the operating temperature and the fans should engage it died. Then I disconnected the sensor again to see if the car would start like when it was cold. But it didn't. With the senosor connected or not, the car would'n start once it's been heated to operating temperature. Any other ideas? Thanks!

UPDATE: I just read on AutoZone web site that you can read the fault code from your car without having it actually plugged to the computer. If you turn ignition key ON/OFF, ON/OFF, ON within 5 sec. the "check engine" light becomes to flash, indicating the fault code. Can someone verify that information? At the moment I'm not home where my car is therefore I cannot try it out myself. List of the meaning of fault codes is also available on the mentioned web page.

yeah, I believe it's a "default" reading, since Chrysler has had it for awhile. The only thing is to count carefully, and pay real close attention, sometimes the flashes blur together instead of separating as they flash each # of the codes.

Ok guys, now I know what seems to be the problem and I'm looking for the solution. The error code was "12", meaning: "Direct battery input to PCM was disconnected within the last 50 Key-on cycles". I searched the web and I found some information on what PCM is. It is Powertrain Controle Module (engine computer). But I do'n know what means that direct battery input was disconnected? Bad cable? Fauly computer? What should I do?

Thanks to anyone who will help!

1] Clean the ground strap, it goes from engine to some part of body, very wide strap.

2] Clean up battery and battery cable connections.

First things first.

Thanks for helping, Knifeblade_03. Situation has gone worse. Car won't start not even cold. The engine is cranking fine, but no start. I checked and cleaned battery conectors they seems to be OK. I also checked if there is a spark and it is. Now I have two questions... If engine has a spark and fuel it should start, right? So I'm guessing there is something wrong on the fuel system. Do you have any idea about how can I check if there is a fuel? Probbably you have to disconnect a fuel cable from some component. But wich component? And where it is located?

Knifeblade · #10 02-05-2007, 01:14 AM

Not really. Even if air, compression, spark and fuel are occuring, the PCM or one of it's related sensors may prevent the engine from starting. U state you got a code PCM, that states it's power was interrupted in some way. time to look at the crank or cam sensors, I suggest www.autozone.com as a way to surf for those issues. I know it isn't much help, but maybe it will lead you to the problem. I am thinking a bad sensor at this point.

BTW, just goto repair guides off that, find your year and make, LOL. I use it a lot, and the Dodge ref. is irrelevant.

I'm thinking of those two sensor too. I went through autozone repair guide and came to those two sensors as well. I'll get back when I replace them to let you know the results. Thanks!

Hello again...

Well, I'm still waiting for Fedex to deliver my sensors. I expect them some time next week. But meanwhile I was doing some engine checking and I found an interesting thing and don't know how to explain it. I found two straps connected to the engine, picture (http://uros.amis.net/car/engine_strap.JPG). Those straps are connected to the engine about 10cm above crank sensor. One of those straps goes to the car floor and it is attached to some metal underneath engine, picture: (http://uros.amis.net/car/strap1.JPG). And the second strap goes to the chasis on the passenger side BUT... it is teared apart, picture: (http://uros.amis.net/car/strap2.JPG).
So, what is the meaning of that strap and is it a big deal if it is broken? Could that be the ground of the car? Could this have some to do with my car not wanting to start? So many questions...

Thanks, BYE!

Those are chassis ground straps, engine to frame [chassis]. That one is broken shouldn't have any effect. That they may have rusty or poor mounting connections and have some effect, honestly

.

It's possible, though, that the lack of electrical discharge from engine to chassis may have some effect on the engine, but I really don't know. Wouldn't hurt to clean up the connection ends, but I don't see any need to replace the broken strap.

OH Man !
I have the same problem with my Eagle. Di you ever figure out what the problem was? Or anyone else know whats up ? I changed the coil pack,fuel pump,battery cables,and thermestat to no avail. Please email me at jd1526@ hotmail I need this car ASAP!
Thanks!

Hello everybody!

I'm glad to say that since today my car is finally back on the street! It took a long time to fix the problem but it's working fine now. The problem in my scenario was the CAM sensor! Camshaft position sensor was to deep in the housing physically touching the camshaft wich was slightly rubbing against the sensor and tearing off the magnet when running. That was slowly killing the sensor.
BUT when mechanic replaced the sensor car still wouldn't run normally but it needed to be disconnected from the battery for several hours as well. I guess the computer needed a reset too.

Thanks to Knifeblade_03 for helping me out!!! I apreciate it! I would buy you a beer but I'm too far away
