I have an '87 GTA 350 TPI. I disconnected the Electronic Spark Control Module (Don't ask me why, crazy idea) and when I turned the key it had a split-second of cranking and turning over then went dead - no noise, but still had full power to everything. I have full power to all accessories, hatch, gauges, radio. I hear the fuel pump click on when the ignition switch is turned to on-start but other that that nothing, no sound or activity. I am showing good voltage at battery and on gauge. Now I'm stuck in driveway since car wont crank. I have had some insights based on another post I have but I am posting this since it is more specific; perhaps new thoughts? Please help if you can. Thanks!

Update:
I tested all my fusable links to make sure they had voltage on both side of link for each one. I then investigated the purple wire going to the starter. I noted it had "0" voltage and imagined that the when you turn the key it drops 12 volts on it to start starter. So I tested my theory by tapping into the purple wire and then touching it to the 12-volt post of battery (with the key turned to on of course) and BOOM it cranked over without a hitch! So now I must investigate why when I turn the key it doesnt drop 12 volts onto the purple wire. Any ideas? Thanks!
