probably ran the fuel lines dry, undo the black bleed screw that's on top of the filter housing a bit and press down on the primer abut a million times till fuel starts to come out the primer then shut it finger tight. then keep priming it till its hard, and start the truck.

 

oh ya forgot to mention that carck the lines it makes it tons easyer

 

black bleed screw is in the center of the pic. it can strip very easily, best way to keep that from happening is just to tighten it finger tight.



its best if you use a the blunt end of a screw driver instead if your thumb to prime it, it takes a long time.

 

damn i wish our cummins had one of those cracking the injectors suck

 

thats pre injector pump. no cracking lines on a CR

 

ya it makes it a pain in the *** when its cold outside

 

Duramax doesn't run a lift pump. The CP3 draws fuel from the tank. Probably loosen the feed line on the CP3 and run the hand primer till fuel shows up.

 

thats whats the bleed screw is for, no need to loosen lines it might die the first start but after that itl turn right on.

i added a lift pump so when i change the FF i just turn the LP on and wait for the fuel to come flying out the bleed. no priming for me.

 

well thanks to all ya'll but i just went over to walmart this mornin and stood in the parkin lot and pressed on the primer forever.(it was cold and i was still tired.) But atleast it works now. after i pumped it forever i got in and yelled at it to work and right after i did sucker started right up i definately ain't gonna let that happen again.

BTW i looked at those pictures from your fuel filter deal thread to know what to do. i like pictures more than a bunch of words...

 

sometimes ya got to talk dirty to em and then they work...im not sure why that happens but it usually works nine times out of ten
