    it sounds like your fuel pump is leaking down overnight I would check the fuel pressure when you first start it in the morning

    Thats what we are thinking. But when i went to auto parts store that i trust he thought might be something else. Like leak in line
    Not seeing or smelling gas but wondering if a vacuum like would allow the gas to not be readily available on start up. Did have pressure test done on pump they said that was good thanks for advice

    have you tried cycling the key on and off 3 or 4 times when you first go to start it?

    Dont really hear it cycling but it is farther back and havent had any one do it while i listen
    I spray fluid right in carb/injector fires first time and stays runnin
    Questioning whether relay or something not sendin signal initially
