hi all I need a little help a good friend of mine has 02 cummins that the power shop says needs a new pump he started the truck one morning to go to work and it ran for little bit and died so he took it to the power shop and they started with the chip said it had a bad connection but after fixing that it would not start so they checked the codes and they found nothing looked at the chip and ever thing looked good tried to start the truck and it started checked the codes and the pump code came up but the truck has never ran better



the chip is a dr diesel
thanks for the help

 

I'm not real sure what you're asking here.
what code came up the first time?
what fuel pressure does it have?
