holley efi no spark
Im running The holley hp efi system. the car was running last night, warming up on the driveway. then it died. I cant get any spark. do the coils need to be grounded,,if not why am I not getting any spark ????? Ideas ???

The list of reasons could be endless.
Is this a new install ? Is it wired correctly ? Are you getting a stable rpm reading with the software when cranking ?
You dont mention what coils you are using ? Easiest answer there is ensure they are wired as per instructions

Coils are grounded via the harness. You should have a large ground that plugs into the ecu and runs straight to the battery. There is another ground (maybe 16 gauge) that should be grounded to the engine near the coils
