Thread: Help!

  1. #1

    Default Help!

    I have a 04 chevy 1500 p/u that will not run.
    Tested fuel pressure, have 62 psi and good spark. i also replaced the ignition switch and nothing changed also has a new battery and alternator.
    So what can i do now? No codes in computer.
    When you would crank the truck over the starter would just stop while holding the key in the crank position, then start cranking, then stop, then crank, etc....So I replaced the weak battery, now the cranking problem is gone but still wont run. checked for fuel preussure and spark, still wont run
    Please help!

    Welcome to the club!!!

    This sounds like a passlock problem, Is there any lights lit up on the dash?? Padlock lit up in yellow or anything else, Passlock will not throw a code either.
