On my way home from work tonight my truck shut down. Shortly before that happened, I had to click the ignition a couple of times to get the glow plug relay to come on. That is the only symptom before the PCM shut down. I keep a new relay in the truck since it has done this occasionally over the last couple of months, especially when it is -20 F like this afternoon, so I was ready to fix that if need be. I had the truck plugged in at work all day and it fired right up once the relay kicked in. Drove about 2 miles down the mountain and she just shut down. Tach dropped to zero like the CMP sensor went out. I didn't have my diagnostic tool with me because it is too cold to keep it in the truck this time of year. Usually I can reset the computer if the CMP sensor goes out and atleast get home. Had my wife bring it from home, plugged it in and got a No Responce message from my computer. Never encountered this one before. My guess is that something major went wrong with my PCM (or maybe a fuse?). No warning nothing, the truck has been running great even in this fridged arctic air that has recently moved in. Took me three hours to tow her home and get her back into some heat. If I had been out of cell phone range I could have died out there. I was pretty frozen when I finally got home. Any suggestions on where to start? Does the PCM have a fuse that could have failed that I'm missing somewhere? Any help sure would be appreciated. Not sure where to start.

Rest in peace, Todd, we will meet again.
what is a super moderator??? you are the first i have seen.......
the fuse for the obd2 port is the same as the cig lighter. check that.
i agree sounds like you have a fuel heater problem, easy fix
or a bad cps, or possible fried pcm too.

I agree, it is a shorted fuel heater. Can it be replaced or does the whole unit need to be replaced? Can I just disconnect it and go without? It is the middle red/green wire I am guessing.
