'86 Corvette, no spark condition. What to check?

Car has run fine for 3 years. Got up one morning and it wouldn't start. I replaced cap, rotor, plugs (wires are only 6 mo. old), no go. Bought a spark plug tester and I'm not getting spark.

Replaced the ignition coil. Still no spark. Took the cap off again, and took out the ignition control module and the guy at Autozone ran it through their tester about 10 times and it passed every time.

I have 13.2 V at the batt term on the distributor cap... I'm at a loss what else to check. Help!

    It is probably the magnetic pick-up inside the distributor . If you don't know what you are doing , replace the whole distributor . Really is a lot easier as you have to take the dist. a part . The pick-up is under the plate the control module bolts to . Shaft and all pieces have to come out .

    With the distributer cap removed and safely put to one side crank the motor over for a brief second or two and see if the distributor rotor turns-it may be possible that the drive gear may have sheared or there may be a mechanical breakage within the distributor preventing it from rotating.

    change the plugs and the plug wires

    try testing if you have power at the ignition switch itself.
