No spark to coil,replaced coil still no spark.fuses and relays good.

IF you have an auto repair savvy friend - get some hands-on help with this one. Don’t keep putting on parts in hopes of getting lucky. Here is a couple links for troubleshooting the ignition system: http://easyautodiagnostics.com/gm/4.3L-5.0L-5.7L/how-to-test-the-icm-1 How To Test A Misfire / No Spark-No Start Condition (4.3L, 5.0L, 5.7L 96-04) This system is fairly easy to test. Good luck with it!

Don’t really have the pick up coil in this distributor .. Got a hall effects switch .. They don’t give much trouble at all .. Shaft bushings sure can be worn out though .. That usually makes em run real rough.
