i have a 96 lumina sdn, 3.1l. car was running good till one day it started to run really ruff. i was able to get off the road and the car hasnt started since. i have no spark to the plugs. i have already replaced the crank sensor behind the harmonic balancer and i still have no spark. i have tried the module and coils in another vehical and it starts right up. any help would be appreciated.
