Recently my truck blew a hole in my upper radiator and started throwing coolant out the truck while driving under the hood. Ever since then my truck been acting up electrical wise. Got stranded on the highway several mechanics looked into it and 1 said it was lift pump but put a new one and still the same problem. Put a new alternator and voltage regulator and still same problem. Pulled the ecm and took it to get checked and also not the problem what else could it be. The truck feels like it gets no power or fuel when I press the gas pedal I have a 01 dodge 2500 24v 6spd 4x4

 

Try doing a APPS reset.

APPS Reset Procedure

This procedure has shown to help 24 valve ISB engines. It is basically teaching the fly by wire accelerator on these trucks to reread the position of the pedal and it's limits. Most complaints this will help with is poor acceleration, improper shifting, bucking in 5 and 6 speeds. Has been known to increase fuel mileage in some instances.

1. Set parking brake
2. Disconnect negative battery cables on both batteries
3. Turn ignition key to run(to drain any remaining capacitors)
4. Let truck sit for 30 minutes( this is the recommended minimum)
5. Return ignition to OFF position
6. Reconnect both batteries and secure, not a timed event
7. Turn key to run position(not start) and depress accelerator pedal slowly all the way to the floor
8. Allow pedal to return to top position slowly
9. Turn ignition switch OFF
10.Release parking brake
