Question about 1990 Ford Mustang
Try starting fluid. Gas is probably bad and needs to be drained. The engine will fire or run briefly with starting fluid verifying a fuel problem.

need to change rotor and cap , and might as well change wires and spark plugs if its due for a tuneup! yeah have your ignition control module check if it doesn't start after replacing every thing else.

disconnecting the battery on an alternator is a no no. that was how they used to ck generators but an alternator can be damaged with no load in the circuit. Try changing out your MAF sensor. 1st sensor coming out of the air cleaner. good luck.

Was looking at posts and other sites. I take it that some relays are even under seats. Anyway, Apparently the ECU relay and the ECC relay are linked. When properly operating the ECC brain sends a signal to the ECC relay and the ground wire is tan/green. The brain can be throwing the signal and the relay terminals are not receiving the signals, so the relays cannot switch.
Although you have replaced some relays, you need to check your plugins for these 2 relays.
