2003 3500 5.9 cummins ?fuel problems?
Hi all! New to this site.............I have an 03 3500 with a 5.9 cummins.
I had some trouble with the factory lift pump a couple months back, and (foolishly?) replaced it with a dodge in-tank pump.
I have not been able to get the truck to run properly since. Most recently, I replaced the fuel control actuator. This did not seem to help at all.
The truck starts only when plugged in and usually needs a charger hooked up, as it cranks a long time before finally starting (40 seconds). The last time I drove it........it would only get up to about 50mph, and I believe it was smoking with the pedal to the floor.
I am thinking it is a fuel problem.........but not sure where to look next? Anyone with similar experience or knowledge on this?
