I want to thank everyone agin from deisel bombers who took their time to help me agin! I found out that my fuel filter housing was bad by pumping the filter houseing 3 times ONLY,
pumping it more than that can cause damage. I noticed fuel coming out of the top of my filter houseing. I found Dmaxwrench.com on the internet and was able to get a life time on a filter houseing for a price. $275.00 for the houseing $250.00 deposit for the old one, I was paid back quickly, and $80.00 overnight shipping. One problem though I tried to get the filter installed correctly but I'm not as strong as I use to be. At first I still had the problem but I found an old style oil filter wrench worked and 1/4 inch ONLY did the trick.
I hope this helps someone the problem was killing me.

 

What were the initial problems you were having with your truck? I'm having some intermitten crank but no-start problems and code p0090. The code is for the fuel pressure reg circuit. I replaced the fpr but still have a problem.
Thanks!

 

I had some hard to start problems, my truck would always start on the fith crank. Then one day my truck died and would not restart, I had it towed home and the next day it started and ran for one more day, that was it. I got some good advise from deisel bombers but I needed a fast fix. I went online and paid one of those master mechanics and was told:

FIRST A WARNING no more than three pumps or you can damage your truck.

Pump the pump on top of your fuel pump three times and listen for a leak, mine was on top of my fuel filt houseing deisel was leaking. I guess its like the fuel injecters gm never got it right they just wanted to get the trucks into production. I hope this helps if I can answer anymore questions just let me know.
