1993 dodge cummins dosent like starting on hills
hey i have a 1993 dodge cummins 12v and it runs great and start cold half a crank and on the flat starts with half a crank... but on hills it likes if you give it abit of gas to fire up or it likes to crank alot to fire up any ideas i have a new lift pump and fuel tank and looks to be a new fuel line from the tank ? thanks for any info :tu:

So it just doesn't fire right away when on an incline? Does it matter uphill or downhill?

ya i just got the truck not long ago and i put the new lift pump in and the new tank but not the new fuel line. i guess i put newer intjetion lines on as well. so anything fuel like should be checked for leaking like line from tank to pump and the line from the filter to the injet pump and some times when your on hills going slow it likes to stall and then crank and crank but aslong as you give it a bit of gas it wont stall and will start great

Sounds like your calibrated return oriface is weak? Allowing fuel to leak from the pump case, and not getting enough fuel pressure to advance timing to start or stay running well.
|
and how would i go about fixing that lol ?
