    I have a 2003 duramax.had it serviced in october. Since then, after every third day or so it will shut off 3 secs after start up. doesnt matter whether its hot or cold. all i have to do is prime the fuel filter and its good to go no problem. anyone else have this? I have talked to a few guys and they have never heard of this. its not a huge problem just a PITA. has anyone heard of this?

    Air in the system or fuel pump going out. I'd start there.

    Put a new fuel filter on it.

    Was the filter just replaced? If so I bet it's the WIF sensor. Slight crack just enough to lose prime.

    thanks ill try those things

    i had all the filters replaced, and they had to tighten the lines to the injectors off of the fuel pump. came loose 1 year after the injectors were replaced from the dealer.
