Truck Died
 

Headed to work this morning, made it about a mile and my truck died going through an s-curve. Coasted through the curves and pulled over. Tried to turn the truck over and it spun fast and strong, no fire. I noticed that the tachometer was not moving. Pulled my spare out of the glove box (recently removed black CPS that was working when removed) and I swapped it out. Still no movement from the PCM. I tried turning my gauge on but the switch was already on (LIGHT BULB!!). My gauge is grounded by the PCM...or suppose to be. Pulled fuse cover off and #30 fuse was good. Popped the hood and #24fuse?? (20amp) was blown. I ddin't have any of the big fuses so I replaced it with my radio fuse. Got power to my gauge now and tachometer registers during cranking but it still will not start. I check cranking duty cycle (40-38%) and ICP (+3k psi). I tried pulling ICP, running out of ideas at the time, and tried starting with no luck. I thought when I swapped the fuse I would more than likely blow it again. Got a tow home from my neighbor. I tried focussing on brake lights and not brain storming what the cause could be. I can hear the fuel pump humming. I'm thinking IDM fuse....a relay?? Any suggestions where to start? I am also going to check fuel bowl heater as well. Do I just check for continuity between the element and bowl?

Man this forum has slowed down....

Checked the fuses again and all under-dash fuses were good. 26/PCM and 24/keylesd entry fuses were blown in the under-hood fuse box. Going to get more fuses today and going to check fuel bowl and relays.

Yeah, it really has. Might want to give one of the larger forums a try.

Usually if I have a serious problem, I post here and TDS to get all input I can. Currently have can 8pg thread going at TDS now. Really hope I find a solution this week so 1: I can get my truck back up and running. A sitting truck is not good. And 2: is like to be able to post what the fix is for anyone else that may have a problem like this.

Got a call from Swamp's Diesel. IDM and PCM tested good

Where to go from here? Pull harness(es) where I can go over it in the open?

Send my IDM and PCM from Swamp's to my dad (live's in North Alabama) and have him stick it in his truck, I don't think it would help but just wanting input?

What relays and fuses MUST be good for the truck to start? Only ones I can think of are #30 under the dash, #24 under the hood, and the IDM relay under the hood.

Where are the fusible links?

Here's the link to TDS thread. It's the main thread I'm keeping up to date.
