Engine shuts off when it reaches operating temperature, is the timing or PCM?

I had to replace the timing belt cover on my van listed above. After I put everything back together it would not run properly. The mechanic said the PCM went out and I replaced it and the Cam sensor. It'll start but as soon as it gets up to running temperature it shuts off. It sounds good when it's idling.

Ronnie,

What you describe sounds like an issue with the crankshaft position sensor. When they start to fail, heat adversely affects them.

Take a look through this link and let me know if it mirrors what you experience:

Also, I am assuming that it runs normally before this started. Is that correct?

Let me know.

It runs normally before it heats up. I just replaced the cam sensor.

Ronnie,

It is possible. If the vehicle has a tachometer, see if it jumps around when it starts running oddly. If the sensor is the issue, the engine will be losing the RPM signal from it, or at least it will be erratic.

Or, if you have a live data scanner, see if the signal jumps around.

Let me know.

Sounds good. I'm interested in knowing if that is the issue. Chances are it is something simple.

Take care and I'll watch for your reply.

Replaced the cam sensor for the second time and it runs just great. I really appreciate your help. One more question, I have a hole in my air conditioner condenser can I just replace the condenser or do I have to replace dryer and all that too?

Hi,

Ronnie, first, I'm glad to hear it is running properly. That's good news. As far as the AC question, could you possibly copy that question to a new thread? We try to keep the topics specific to one issue, so it is more helpful to others. I hope you understand.

Here is the link to start:

As far as your new question, there are variables and PAG oil will need to be added to the new condenser. I will watch for your new post.

Take care,

Joe
