Hi,

I have a 99 Dodge full size van AB, when I got it, it was missing an AC condenser which I got a new one and install it and fixed the AC now its working great.

But the vehicle has a problem since the beginning, when let it sit there idle for about 30 mins after it warms up the car just shuts off. So I went and bought a code scanner and let it died like usual and try to hook up the scanner but it saids NO LINK so the power going to the ODBII died.

Can anybody know where I can start with this problem?

Fuse is fine, the problem is the car just died when try to start it just crank, but won't start. But if you wait a while it starts up again and run a while and shuts off the same problem.

What else could it be?

One more thing I notice, that after the van turns off, when try to crank all the power going to the dashboard also died. All the meter stay at 0. All electrical just died.

Could it be the PCM? Please help.

Would check connections at the Power Distribution Center in engine compartment. also check for spark when won't start and fuel ie. spray carb cleaner see if it fires

Power Distribution Center is the first thing I check all the fuses and relays are ok. All getting power nothing burn. I think its some kind of electrical problem.

Do you have a wiring diagram from the PCM out?

Fuel relay still works fine all getting electricity.

Where can I check for spark?

Hi,

After all the testing, it seems that the ECM when it overheat it shuts off. The ECM sit right on top of the frame on top of the engine so it gets heat up real quick.

Is there a way to protect it? Is ECM suppose to do that when it overheat?
