    2003 VY Executive Manual
    Hey guys, I have a 2003 VY executive converted to manual. I bought it converted. Pretty sure it still has the auto ecu and loom as gauge cluster shows it in park. I put another motor in it and now it won’t start.
    Has no spark, replaced cam angle sensor, crank angle sensor, oil pressure sensor, coil packs and leads. Don’t know what else to try
    Does anyone know what to do to get it running?

    Welcome to the forum.

    Have you removed the PCM?

    PCM/ECU is located in the passenger side kick panel,

    Was it running before you swapped the motor?

    You haven't mentioned swapping the dfi.

    Yeah, it was running, tried disconnecting the ECU and plugging it back in with no luck.

    Where did you get the crank angle sensor from (if from eBay) try swapping it with the one off the old motor.

    It was running before we swapped the motor over. We swapped the DFI over as well and still nothing.

    Swapped every fuse and relay for new ones. I got the crank angle sensor from Metro Auto Spares, so it’s a good one.

    You said you had no spark, did you remove a plug lead and got a old plug and leant it on the engine and cranked it to see if the plug is sparking? Have you tested power to the injectors when key is on? Have you tried start ya bastard in the throttle body while turning over to see if it will fire?
