    Default hard to start/4.3 v6 chevy truck 2006

    Anyone have any idea's? When I go to start the truck, the motor will just spin and spin like its getting no spark or fire. If you keep on spinnin, it will finally start spittting and sputering till it finally starts up. Seems to be worst if I leave it sit for a day or two without running. But once it starts, it runs just fine. I have 90,000. miles on it I put new plugs, and air filter, but still problem exsist. Any help would be appreciated.
    Thanks Gbav1

    Sounds like you need to take a look at the fuel pressure regulator. Since if im correct the 4.3L hasnt changed much in the new trucks it is under the upper plenum, and can leak down.
