No Spark 87 2.8 Camaro

I have a 87 2.8 Vin S, I don't have any spark, here is want I’ve replace, the dist, the dist module, pickup coil, cap, rotor, coolant sensor, TPS and replace the pickup coil again, it was bad, I thought I had it repaired with the new pickup coil, but, still no spark. I replace the ign coil as well. Thanks for any help.

I have power going to the ign coil and the wires going from the coil to the module (2 wire harness) are both hot? The rotor turning. The times before I got it to run, it would run and all of a sudden it would turn off like someone turn the key off. I read somewhere that when you turn the key on, it sends power to the ign module? At this point I am thinking ign switch or the ECM??
Thanks for any help

Check the electronic spark control, it may be bad.
