I have an 07 5.9 cummins and when I am into the throttle the engines cuts on and off like someone is flicking a switch. it starts around 2500 to 3000 rpms. I changed the fuel filter and no difference? Thanks for any help on this.
No, I dont have a gauge. I went to start it today and the engine died like it was running out of fuel. I got these codes P0513-invalid key shim, p0234 - Turbocharger overboost, p2509 ECM/PCM Power input signal intermittent, and p0251 - injection pump fuel valve feedback. Got no clue what is going on now.
Figured out that the key fob has a microchip in it. I used a copied key and after you start the truck it senses no microchip and kills the engine. The truck still cuts out when I am getting on the throttle though. I will look at the FCA. Thanks Wildbill!
i'm really interested in what you find out my 07 5.9 just started doing the exact same thing on the way home from terre haute except i have no codes and i just replaced the injectors today and that did not fix it
I had this happen to me but all the lights came on like I was trying to start the truck. I have read where it has happened like you are saying. I turned the key on for 10min then off for 10min the back on for 10min and that seemed to work for a while. The stealership offered to reprogram my keys for free after that so I don't know if that will really fix it, but worth a try. It is a simple fix. I had no codes for a long time then the skim key code was present. Let me know if you try it...
