    2004 virage I 800 runs good, then won't start after warm

    My 2004 virage I 800 twin starts, goes perfect, then after I turn off the ski, it won't fire back up!
    cranks over good, plenty of voltage, won't fire up. After it cools for 1/2 hour, then runs fine until I shut it off again, then same wont fire up. DFI EMM 4 hours ago. New TPS 2 hours ago.
    any ideas before I go buzzerk & start replacing things?

    Bypass the LR-503 Start/Stop module for testing.

    If still no warm restart, check voltage on White/Red wires when cranking. All injectors plugged in, should measure over 20 volts DC between White/Red and engine ground.

    My LR503 is toast~ anyone know where I can get a 4010906 ?
    Thanks K447 for the diagnosis lead, do you have a direct link where I can donate to the cancer "ride for dad" fund? I did see others have a link.

    The 4010906 isn't available. I just tried to get one for a customer.

    Ok, now I'm quite frustrated. Bypassed the stop/start ~ ran great, thought it was the problem, then it died idling. Cranking, but No start. possible exhaust water temp sensor? or is my 6 hour rebuilt EMM toasted?

    All you can do is go through the diagnostics afresh.

    Don't assume anything that tested good or was eliminated as a possible problem cause is still good.

    Injector voltage check, unplug TPS, and so on...
