1994 Lumina APV mini-van, 3.8 L, cranks but won't start. No spark.

Engine ran OK until I replaced the lower intake manifold gasket, plenum gasket, and valve cover gaskets. I also replaced the radiator. From that point on, engine has had no spark.

The Ignition Control Module checks out OK. I replaced the Crankshaft Position Sensor too. Injector harness plugs show voltage across terminals on a voltmeter, but will not light a 12 volt test light. (I don't have a noid light).

I checked the fuses in the glovebox, they're all good. I suspect there are other fuses elsewhere, but I don't know where they're located.

Any ideas?

Thanks,
Tom

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