I have an 89 k3500 454 tbi not getting fire to plugs. have fire to and from coil, aldo has new coil ignition module ingnition switch distributor cap rotor button distibutor and starter. but no fire to plugs

Pulled this out of a dark spot in my mind... check that the coil mount screws have not pushed through to the inside of the cap causing an internal short, pulling spark to ground. if distributor is new pickup coil should be ok but check for broken wires there just in case. Also if you have a tach, disconnect it from distributor. If internally shorted it won't get spark.

Check the resistance of the pick-up coil in the distributor. Reading should be between 800 to 1200 ohms. Disconnect the two wire connection at the distributor control module to measure the resistance.
Let me know.
Regards,
