Good Morning. Since it was cheaper to go buy a sensor($10) than find a scanner I ran the truck until it stalled (about an hour run time) then replaced sensor. That didnt work. Ok, so I am looking at the wiring diagram you included( thanks) I am inclinded to think the PCM itself may be the culprit. Do you have an image of the PCM connector and can you point out the connectors (with voltage values) so I can do some checking(DVHM) once I pull out the PCM?
I am back with the information you requested. Below I will post the Basic ECM power and grounds. Next will be the ECM pin outs. Since its a larger amount of information I have it as a Portable document file (PDF) To read it you will need to download and install Adobe Reader, you can get it at the link below

After that is installed please go to the below link to download the PDF I have created.

Follow the below pic to see what to click to download it; Let me know how I can help further and again my apologies on the delay.
Can you send this information directly to my email address as I'm not comfortable with signing up for some account I will probibly forget about and have to find a way to cancel and get money back when they automatically take it from my account.
