HELP! Was idling then just quit!!
:scare2: 2004 duramax....Cranks fine... was just sitting there running then it was like someone shut off the key. Im sure i can fix it if i can get some hints on where to start. not sure how to tell if its an LB7 or not. Thanks in advance!
---AutoMerged DoublePost--- I know im a newbie guys... gotta start somewhere!! Help a "brotha" out please...... |
Does it start back up fine? Is the priming pump hard to push after it stops? The vin tells you which motor the 8th digit 1=LB7 or 2=LLY.

Def check the underhood fuse box for any blown ones. Can't remember what fuse we used for his kill switch for his emergency shutoff but with that fuse out the truck will only crank and not run.

my 2001 was having the same problems and i couldn't figure it out to save my life it turned out that my return lines were shot my fuel rail pressure was only at 1400 i believe it is supposed to be at 4000. but anyway it was the return and once i got that fixed it ran great. but was your truck going into limp mode before or were any dtcs showing up?

It had lost its prime... kinda like me :-) pumped it a few times and lit right off... no problems since.

Is it still good? Seems kinda funny it did that must be a leak somewhere guess youll know if it does that again..
