1984 Auto No Spark
I've replaced the ignition control module but it didn't fix the no spark issue. I'm also not sure if the injectors are firing. Fuel pump is definitely working if there's any questions you have then I'd love to answer them.

Alright I think I found it. There are 5 wires that I found are cut under the car and they all seem to be part of the ignition system. They are pink with black stripe, solid pink, solid blue, tan with black and maybe solid tan.

When I replaced the coil and ICM on my '84 with Pertronix Flame Thrower parts the coil had white, black and red wires, no yellow. Perhaps you have the D3000 coil which has the yellow wire. The D3001 is the correct white wire model for the '84

Summit Racing site says they both work but Zip say the yellow wire version is for 75-81 only.

Im still having a no spark issue. I've replaced the distributor, ignition control module, and the ignition coil but still no spark. could it be an ECU issue or a wiring issue and is there anything I can do to test for either?
