I just bought a 97 F250. I knew is didn't run when I bought it, but the price was good to pass up. The previous owner said that all it needed was an IDM because of water intrusion. He showed me the inside of the IDM, and I could see all the corrosion. I installed a rebuilt IDM, and still crank no start. My question is can a bad PCM also cause a crank no start. When I turn the key on, I have no CHECK ENGINE LIGHT. However, when I ground pin 2 from the PCM connector, it lights up, so I know the bulb is good. I checked power and grounds to the PCM, and they are all present, so I am suspecting a bad PCM since the CHECK ENGINE light does not come on with the key on. I also have power and ground to the IDM as well. Using a scanner, when I ran the injector buzz test with the "new" IDM and I got the following codes:
P1293 - High Side Bank No. 1 (Right) Open
P1294 - High Side Bank No. 2 (Left) Open
P1274 - Cylinder 4 - High To Low Side Open Detected
When I pulled codes from the PCM I get a P0603 - PCM Keep Alive Memory Test Error
Can a bad PCM cause the IDM codes? Can a bad PCM also cause a crank no start? Do I have a bad PCM?
I am a professional mechanic, but I don't work on many diesels. That's why I bought one.
Thanks for all your help in advance.
