94 no spark.
 

i have a 1994 lt1 and I'm not getting any spark to the optispark distributor. The ignition coil has been tested and checked out. I've heard it could be the crankshaft sensor?? any thoughts?

Your car does not have a crank sensor. That job is done by the optispark. If the coil is good, check the ignition module, if the module tests good, check all wiring & connectors beteween opti, ignition module, coil & PCM. If all is good, it may be opti time.

^^^ agree. how old is the opti?
