    Default Service engine soon and priming the engine

    My service engine light comes on intermittently. Also I have to prime the system the same. Mostly when I drive for a while and the outside temp is hot. Above 80. I have a edge juice on the truck no moniter. The condition was happening quite alot when hauling my camper using tow haul mode. Juice at zero. Thanks for any info or fixes.

    Remove the Edge and try again. Diagnostics does no good with it connected, and a little vehicle info might be helpful.

    If you have to prime the fuel filter to start, you have a fuel (air) leak. Change the fuel filter and/or verify it is installed correctly. In most cases, it's as simple as that.

    ok. I will give that a try. The truck is a 02 Sierra with a cold air intake and 4" exhuast other then that all stock. Changed the head gaskets in Feb 2010. It has been awhile since I changed the fuel filter though. Thanks

    It would be nice to know what DTC is being set.

    I was only running level 1. Stock on tow haul. Not sure what DTC is.

    DTC = Diagnostic Trouble Code: The code that will be present any time the SES lamp is lighted.
    As John said, it is helpful to know the code to aid in the diagnosis.

    The Edge level is not important. It must be removed to eliminate it as a cause. If it was, it wouldn't be the first time. However, if the condition and SES can be repeated, change/repair/remove only one thing at a time. If you change more than one, you won't know what was the cause.
