ok a buddy of mine has a 2001 dodge 1500 pick up with a 5.9l in it, and for a while now when you go to start it it cranks and cranks and cranks, probably 15 to 20 times and then it stumbles to a start, he's put 2 or 3 different pumps in it, and he has replaced some other things too, but i could not tell you exactly what has been replaced. now when it runs its like 60lbs of fuel pressure or so (i dont remember exactly) but then when you shut it off the fuel pressure does gradualy drop like 20lbs. just wondering if anyone has any ideas because he cant figure it out.
