2002 24v cummins, bone stock, 106k miles, reman-ed injection pump (dunno when, just bought the truck). Since yesterday the truck takes a long cranking time (bout 10 seconds) before it will start. in all my experiences, these things start on the second or third rotation of the motor. Haven't taken a look at it at all, just wondering if anybody has experienced this. btw, its about 40 degrees ambient temperature around here.

 

Do you have a fuel pressue gauge?

How does it run once it's started?

 

no guage on the truck, but I do have one I can hook to it. Runs great once it starts n warms up. I'm gonna start with the lift pump tomorrow. fuel filters new as of 1k miles and I know my diesel's good

 

Does it do it every start, just every cold start, or just on random? My truck sometimes gives me a hard start when cold but its few and far between....I couldn't figure it out neither could dodge...

Check and make sure your batteries are giving you a good cold amp. Just a shot in the dark, my uncle had a problem where the battery connected to the starter wasn't holdin enough amps in cold weather (it would turn over but had hard starts) and it was tryin to pull amps from the aux bat...swapped um and fixed the problem....

 

FIXED IT! Don't fuel up at ARCO! bottle of cetane boost and topped it off with 76 n tonight when it was cold started like normal.

 

oh god, arco gas is always garbage around here, i cant imagine what thier diesel is like.
