For any reason, did you remove the spark plug wires and have them mixed up? Chances are you would have fried a fuse before you would fry the ECM.

Firing order is correct, I didn't remove anything, was changing thermostat and housing, alternator arked on filter box which was still sitting in the carb, there is a sensor on the carb just don't know what it's called. Idk if I messed something up in carb maybe? Car was running perfect before that cause I moved it out of the drive way under the tree to work on it. 😑😑

That's an electronic solenoid and will still run EVEN if you unplug it. Do you have a good and hot spark? Blue ark? If its yellowish it may be too weak to fire.

Check the fuseable links by the starter. Maybe.

OTHERWISE...

From my experince; fuel, air, spark - still not firing = Bad ground. When it happened to me it was the little wire off the negative terminal to the fender. Spark was there, but not strong enough. Didn't even cough until I found that was not connected. Fired right up after.

Gonna replace coil when I source a new one, replaced cap rotor plugs wires and it fires hard just won't start. It turns and sounds like it wants to start but just won't.
