04 gmc wont stay running?
I have a 04 GMC 5.3 that wont stay running. I gave a jump to my son the other day and the truck was not used for couple days. I went to start it and it wouldn't start so I got a jump. I went to take off and it just died. I restarted it without a jump but it wont stay running. acts as if its not getting gas. the alternator is charging. I charged the battery over night and its still doing the same thing.
