New:FI pump,trans. pump, htr. relays, still no start below 50
Hard start in the mornings, starts no problem with plug-in, or ether. But never starts fast hot or cold. with plug or ether it still takes a lot of turnovers to start. new batteries. Will not start without ether or plug below 50-60 degrees. New transfer pump, new fuel injection pump, new heater relays, and mechanic says pressures and heater is okay. mechanic is scratching his head looking for ideas.
2003 2500 5.9L Four-door, four inch open exhaust, runs strong (when it starts)
some of my thoughts from reading this thread are: rail pressure relief valve, return flow of the injectors??? could these be right?? any comments or help would be appriciated.

I know this sounds dumb but I gotta ask clogged air filter??
if not sounds like you need a scan tool to see what everything is doing or not doing.....
how does he know the pressures are ok?? is he using a scan tool?? or do you have a fuel pressure gauge??

two new air filters with no change exept when i didnt get filter in good and it blocked the air flow and shut down at about 2500 to 3000 rpm.
i will ask mech about scan tool,i believe he has a snap-on code scan
