I have 2002 2500 I just had a new injector pump and fuel pump put on.
It starts good when the motor is cold an runs like nothing is wrong with it until I kill and try to start again. It's acting like its not getting any fuel. And had fuel pressure check at idle steady 12-13psi. Any suggestion on what could be the problem would be much appreciated

Usually a hard start while engine is warm can be a sign of a weak injection pump. Assuming you have no air leaks. Are you getting any codes or check engine light?

 

No codes are coming up and check light is not coming on

 

AWO, when it is warm and you know it will be a hard start, pour a half gallon or so of ice cold water over the VP44 and then see if she starts right up.

All Injector pump rebuilds aren't the same quality, where did you get the pump from?

 

I ordered the pump from thoroughbred.com
