Hello my name is Tyrus I have a 2005 lly duramax deleted and what not no lift pump and I’m having trouble getting her down the road. Just did head gaskets a week ago been running great since then but now it seems it won’t hold a prime. Can pump it up and get it started runs for about a minute then dies pump it up start it runs same thing. I’m fairly new to diesels so looking for any help I can get but I’m thinking maybe fuel filter housing or something of the sort?
