I was on my way to Texas for the weekend for a GNC race, just before I got on the interstate my truck went nuts. I had a 44' enclosed behind me (12,000 lbs) and was accelerating up a very very small hill, going about 30 MPH. All of a sudden the truck lost all it's power, engine light came on and it started knocking real bad. I shut the truck off got the trailer unhooked and drove it, it ran like new for 10 seconds then fell flat again. It has NO POWER, knocks worse than a ford and shifts hard. I was running my edge on level 2 when it happened but unplugged it after I unhooked my trailer. Any advice???

I'm hoping to get this fixed fast so I can get down to Texas in time for the race.

PLEASE HELP!!!

My truck did the same thing . I tsounded like a tractor .
for the fix look up John Deere in the search forum. It is caused by the wiring to the ecm if I remember correct

I think the TSB he may be referring to is the one that says the wire harness can wear through where it is attached to a bracket on the motor causing an injector to short out. I don't remember what bracket it is but, while standing in front of the truck it is on the left side of the engine right near the oil fill tube.

Update: I went to auto zone to run codes. It was something like "injector relay error cylinder #7" So you guys may be right about the wiring harness. I'm going to check that right now.

You guys are awesome!!! Diesel Place Rocks!!!!!

This happen to me in Ok. There is a fix for it. the wire on the injector connector is braking down. they have to put 90 degree ends on the # 7 & #2connectors. If you un plug the connector wiggle the wire & plug it back in it will probably run ok. had to do this 6 times to get home from Ok. Tell the dealer it is that and they have a fix for it.
