Turn the key and nothing - Page 3

The battery was disconnected overnight, no luck, tried 3 different keys, no luck. It's at a friends shop now, he has another guy that is good with Chryslers looking at it. Everyone is perplexed because of how sudden the issue was. No problems leading up to the issue.

Apparently there is a receiver for the "chipped" key in the steering column. If it needed to relearn for any reason and I interupted the process this may be the result, a dead vehicle. Does anyone know how to force it to relearn? This is a stab in the dark, I have a really good tech on it and he is lost right now. He doesn't know the relearn sequence but is searching for it. He ordered and is waiting for a special "key" for his computer so he can look at the van computer components in detail.

Now they are leaning toward replacing the PCM and/or BCM, I thought I was told the car would crank over even if the PCM was bad or burned out, am I wrong? The guy has roughly 8 hours of time invested and is no further ahead as far as diagnostics go. Is it possible for a PCM to go that quickly without any indication? Would the car still crank over if the PCM is bad?

Totally Frustrated

I explained to you in post #24 how to try and start the van did you try it?

I didn't read all post but with the security concern,with that van if thats the problem it would of started and died a few times before the no crank,so thats not whats wrong unless it did that.So here we go!1. Verify the Crankshaft Position Sensor (CKP), Camshaft Position Sensor (CMP) or their wiring is not shorted to ground.

2. Verify the Manifold Absolute Pressure Sensor (MAP), Throttle Position Sensor (TPS), A/C Pressure Sensor or their wiring is not shorted to ground.

3. Test the power supplies at pin 20 on the C1 connector. Pin 46 on the C2 connector.

4. Test the ground supplies at pin 10 on the C1 connector. Pin 50 on the C2 connector.

5. If the powers and grounds are normal and the sensor or their wiring is not shorted to ground, replace the PCM.Good Luck

Dealer only to set up the new PCM,they are a big problem!

I think I read in one of your post that you did not have a ground to the starter relay, looks more and more like the PCM and a bad pcm WILL CAUSE a no crank.

Yes, I could get the car to crank over but it wouldn't start.

I found a PCM rebuilder online, they guarantee the PCM they send you for 1 year and guarantee all the newest updates. What they need to program is mileage, VIN, Part # of current PCM if possible. Anybody have any luck with these companies? Less than $300 shipped via 2 day express shipping. Would the PCM fail overnight?

Did you do exactly like I told you. Key in run position and jump it at the relay. If the pcm is good and getting power from the switch and you jump the relay it should start. If the signal is not right from the TRS the computer does not know it is in park or neutral. Also a PCM is warrantied for 8 yrs or 80 thousand miles. It is less tha 8yrs old. How many miles on it?

zukdj · 02-29-2008, 05:15 AM

Yes, I did exactly what you said, it would turn over but not start. The van is a 2002 with 90,000 mles on it.

Ordering a new computer tomorrow, hope this is the problem.

Read this. It gets to the PCM towards the end: http://www.automotiveforums.com/vbul...d.php?t=887164

Sounds familiar but I'm buying the rebuilt PCM, my BCM is fine. I have the factory anti-theft in the van, the computer rebuild company (SOLO) told me they would make sure it was programmed to original specs and options via the VIN number. In order to purchase from them I have to provide them the VIN#, mileage, and part number of the one in the van currently. I've check out everything else and it all points back to the PCM.

$285 for the PCM, next day delivery. I'll let everyone know if it resolves the problem tomorrow evening. Wish me luck, lots of it!
