I am confused. Tried to fire engine yesterday and I am not getting spark.
Harness was from 96 LT1, but I added wiring for cam/crank/coils from an 02 truck.
Wiring checks out, checked every single one, end-end.
Injectors/coils were swapped for firing order change.
Bank assignments changed for firing order change.
I have it wired per GM diagrams on cam/crank sensors.
A google search seems to indicate eficonnection says pins A&C should be swapped on both cam/crank sesnors.
Hoping this is my issue? But why would it be different/required?
