I replaced coil & module on running rebuilt now no spark?

It did not start. Fuel pressure good & power lead and fuses are good.

I had replaced a known good coil & module combo with new AC Delco parts but had not started the engine since replacement. Now it does not start. No spark. I suppose the obvious answer to the no spark is replacing the combo again.

Any ideas?

Check the crank sensor

Thanks for the response. I replaced the coil/module a second time, and this time with a known good combo. Started right up so now I have either a bad coil or module or both. The first replacements were new AC Delco parts right out of the box.

There is or was a spark tester available from Casper's, I guess I will have to look that up. Maybe another chance to spend some money. Just what a turbo Buick owner needs right!?!
