Thread: Holley HP EFI, no spark.

  1. #1

    Default Holley HP EFI, no spark.

    I hope someone on here can help. I have an LS6 that ran for about three minutes then shut off when I touched the throttle and won't restart. It's fueling, but no spark.
    I've reflashed the firmware to V6.
    Changed from sequential to batch fire and back again.
    Checked and rechecked grounds, connectors & fuses.
    Performed TPS Autoset.
    Cam & crank sensors are working.
    Should I have a live to the coil packs with the key in 'on' position? As I have nothing.
    Any advice or ideas would be much appreciated. Thanks, Will
