i have a 2002 dodge 3500 cummins. when driving it and trying to accelerate there is no response as if the accelerator is not being used at all. i changed the throttle postioning sensor and this has improved a little but the problem is still there. my next guess would be supply pump to the injector pump. maybe a fuel supply problem?? had anybody had this trouble and if so would you be so kind as to help me.

Thanks

Post this is the Diesel in Distress forum. I might need to reset your TPS. Check codes and fuel pressure before and after the VP44 at idle and when you get on it.
