Thread: Hot Starting Problems

  1. #11


    OK well I did a little test of my own. What I did was started the car for roughly about two minutes, shut the car off, waited about five minutes then tried to start the car again and nothing. It didn't even try to start. Now could it still be the After Start Enrichment? Where do I check from here?

    Not if it didn't even try to start.

    Use a timing light to ensure there's spark (& fuel) when trying to start.

    Also, ensure all the fuel injectors are operating. You can use an injector noid light (LINK), an injector probe (LINK), or even
    a long screwdriver used as a stethoscope (placed between an injector and your ear, listening to each working injector).
    Other less definitive methods for MPFI applications, include infrared temp gun readings on header primary pipes,
    or a wet rag on header primary pipes. However you do it doesn't matter, just confirm combustion on all cylinders.
