Hi Everyone, I would really appreciate pointers on troubleshooting my hardworking old friend 92 Yukon.

Running fine, stopped in the yard. Next day won't start. Cranks fine, but not even a cough. Smell fuel at exhaust. Direct connect ignition coil to test sparkplug: No Spark.

Replaced ignition coil on a guess; it looked 1992 old. No fix; no spark.

Distributor replaced 3 months ago; has been running well.

Where can I check/probe:
* 12V to ignition system
* Distributor module?

Any ideas and suggestion Very Appreciated! Winter coming; need to get more firewood in...

Regards, Terry King
