I have tried 4 differnt pmd's. 2 different computers. checked every fuse. it cranks over and acts like it wants to start every so often and i have fuel from the t-valve but it will not start. It ran fine last night when I parked it this morning I went out and it just cranked

 

i finally found the issue, when the shop fixed my exhaust they broke a ground strap, it must have been grounding out on the exhaust yesterday for it to have started.

 

So that must not have been the problem, this morning it is doing the same thing. After I got it started yesterday I drove it all over the place leaving it for hours at a time and when I came back it fired right up. This morning I have the same thing, crank crank crank and white smoke out of the tail pipe but no fire. I checked the ground I fixed, its still good. So what could it be? I tested the wires going to the glow plugs and they have power.

 

sorry we could not help or were late to the ball game, have fun with the running truck!
