going down interstate.... then BAM!
First off - I'm driving down the interstate 70mph and all of the sudden I lose tension on the pedal. I initially thought the truck had died... but when I started to slow down I realized that I could still run about 30mph. I would give it more gas and get no response. If I kept the pedal steady, I could keep it at 30mph. It sounded rough, but not jumping around.. just sounded like an old tractor. I thought it may be the fuel filter - so I changed it. This did not help. When I let the truck sit for a few minutes, It will start fine and run fine for a few seconds.. long enough to get up to speed, then fall on its face again. I just had injectors installed 2 weeks ago, since then I installed a diablosport predator on 65hp setting - and adjusted the tire size to my size. 285x75x16. No issues before this happened. No warning at all.... Please help.
thanks! |
Try taking the predator off of the truck and see what it does.

took predator off - still same thing..
found these codes.. Fault 1 of 3 - P0204 Injector Circuit Malfunction Cylinder 4 Fault 2 of 3 - P0380 Glow plug/heater circuit malfunction Fault 3 of 3 - P1261 Unknown Fault. |
It almost sounds like you lost an injector. I don't know a lot about the duramax though.

He just got done installing factory BOSCH reman injectors, so I doubt they are the problem.
Any other ideas? |
moved here for better exposure

it sounds like to me that your wiring harness for your injectors might have gotten pinched inbetween a valve cover when they were putting it back together. sometning is grounding out if its throwing codes for your injectors that were just replaced

Exactly what I am thinking. :scare2:
|
i would take it back where it was done at and have them fix it for free if thats the case. i would do some checking to see if its something obvious. but i would check connectors to the injector wiring harness if there is one. then check around where it goes into the valve cover and see if its smashed. i would bet its probably one of the wires under the valve cover, its a 2 piece valve cover and when they were putting the top piece of the valve cover on ill bet a #4 injector wire was in between them and pinched it. or mabye the nut holding the wire to the injector is loose. there is alot of stuff to check and its a pain the :moon: to get the valve covers off but it has to be something when they replaced the injectors. im not sure which side of the motor has inj.#4 but start on that side

any news?
