5.7 vortec has like a dead spot in gas pedal. no power really bad going up hill. new gas pump, tps
How about a year and a model. Mileage and recent maintenance would help. What was the rationale for replacing the fuel pump and TPS?
2000 3500 , the garage said low pressure.
And did you start with a fuel filter before the fuel pump? After putting the new pump in how is the pressure? Was there a known problem with the tps or was it a guess? If there was a known problem did anyone check the wiring for the tps? If it has a MAF sensor, clean it.
