I thought of than and had wrangled that issue on a few vehicles. I applied some Stabilant 22 to the pins in the PCM, then cycled the plug in and out a few times. Didn't help. That stuff is amazing stuff. It's made for the airline industry to combat fretting. It's expensive, but works amazing.

Jon messaged this morning to send the PCM in. I'm go to try FedEx's 2 day. Hopefully it will be more quick than USPS's up to 5 day national delay?

Jon tested the PCM and it tested fine and started his truck ok. While the PCM was gone. I started checking the grounds. I haven't given that any thought since my truck is a New Mexico truck with zero rust. The first ground I checked was the PCM ground. The paint on the fender was not removed and the head of the small bolt had paint on it. So the ground lug was sandwiched between paint. I fixed that and after installing the PCM, it's been starting and running fine.

I would recommend everyone to check their grounds when they have time.

Thanks for the replies and hopefully this will help other
