GM Coil and Module Help Required

Despite what post #6 says, your problem is probably listed in post #5. Reversed p/up leads does NOT result in no spark. The signal [ for spark ] is generated as the reluctor passes the trailing edge of the pole piece. When the p/up wires are reversed, it fires on the leading edge. The difference is usually about 30 crank degrees. However, the rotor-to-segment relationship has changed such that you can get crossfire in the cap. Result can be backfiring, engine kicking back, but it still produces a spark.
