2003 dodge ram 3500 5.9 gas starts fine then runs like crap for about five minutes then runs great until you shut it off then it does the same thing if you try to go sooner it will just stall know it getting hard to start poured so gas in the trottle body it fired up with turning it over and over once started ran fine replaced plugs coil computer ign mod cad could it be fuel pump
started fine runs bad for five minutes then great turn it off runs bad for about the same
even worse stalling does its thing then runs great know its having problems starting had
to throw alittle gas in the trottle body started but not right away replaced in the last year
plugs ig mod coil cad mabe pump on its way out
Checking the fuel pressure would help determine if it was the pump.
I don,t think its the fuel pump because once it bstarts and goes through its thing you can drive it 3 hundred miles with out a hicup just dont shut it off its starts right away it just runs like crap for awhile thanks
