I think the PCM needs to be replaced agian I really need help Thank you for your time. Bill Lewis
Bill, please list the model of your truck and what engine it has (specify gas or diesel if you have a 5.9L). Also list all of the symptoms and all repairs done to correct the problem, and what the results of these efforts were.
We can't tell much from your question. It sounds like you replaced a fuel pump and PCM and you want to change the PCM again or maybe the alternator, but we don't know why. Do you have a fuel problem or a charging system problem or both? Does the truck run? Is the battery voltage low? Is the check engine light on? Is the fuel pressure low? What PCM pin got burned?
Ok sorry
318 auto it would not start one day it was like it had no gas primed the carb it would run so I put a new fuel pump on that was not the problem primed the carb again it would run no gauges would work drove to autozone they gave me a code I dont know what it was but they could not find it in the computer the dealership told me they could not help me without seeing the truck for a fee the pcm had a burnt pin so I bought a new pcm and replaced the pin on the wire it started up for about for a short while and I mean short. the pin was burnt again this wire goes to the injectors the alternator fuse box and the fuel pump I had the alternator checked out it was bad I have not replaced it yet and my truck is still apart My question is do you think the alternator could be what is blowing out my PCM
Well no wonder it won't run... someone ripped your fuel injection out and stuck a carburetor on the manifold.
I was wondering about that, Tom...
I must have one of those adkins 99 rams...no carbs....
OTOH, I'd rather be blown that injected...

Anything is possible. How many expensive parts are you willing to replace before you have it looked at by a professional? I know they are expensive but you may save yourself some money in the long run by having someone with the right test equipment go over the charging system.
