Ignition/ pickup coil issues

I bet you are on the wrong track. Access the coil+ with a meter and see what you have with key in "run." Should be anywhere from 8--10V. Then crank it and WHILE cranking read the meter. Should have AT LEAST 10.5 or more. This voltage should be nearly same as battery voltage when cranking

The "run" (IGN1) CIRCUIT is ONLY HOT in "run." It goes dead in "crank."

The "bypass" circuit (IGN2) is usually brown, comes direct from the ignition switch, and connects to the coil+ side of the coil

Check/ clean/ replace the distributor connector, they are troublesome. Make CERTAIN the ECU has a good ground. Scrape the bolt holes and firewall, and use star lock washers.

Do the "in/out" on all the connectors several times to "feel" for tight and to scrub them clean.

Another test is to turn the key to "run" and disconnect the distributor. Take hold of the engine side of the connector (not the distributor) and tap the exposed terminal on ground. Each time it should make one hot "snap" spark. Test this with a WIRE coil wire, NOT a resistive one. Even low voltage wire will work, "rigged" to some sort of test gap. Spark should jump at least 3/8 or more usual, 1/2" nice and hot and blue
