Well, I said by my experience. But then again, I do recall both components being bad at once during my experience. The pinched wire being a second experience. So yes, you are correct as I'm thinking I have never seen that with just the coil going. That was my bad recollection, apologies. But if the Spark control is bad, No prime. So I suggest this fella check that out.

Remove the plenum and check the connector at the injector, (there's only one injector). There are two wires in the connector and it's known have issues with a poor connection. The connector is available at most auto parts stores and can be soldered on to the original harness with 60/40 lead/tin rosin core solder.

How does it go on a 93?

I also am dealing with a stubborn NO START. Have in new distributor, rotor, picked up new coil today, to try that......
