Electrical problem
1985 GMC S15 6 cyl Two Wheel Drive Automatic

No spark from coil. How do I test the coil and where does the power come from?

Get a repair manual and check the primary and secondary windings resistances with a DVOM. The power comes from the ignition switch

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it
