If the distributor has points like the ones below under the distributor cap, the ECU or "ignition box" is worthless

Or if it has magnetic pickup (black cylinder) and reluctor (metal gear with arrow) under distributor cap, you have electronic ignition

I suspect you have electronic ignition and you are not getting spark.
Question 2
If you remove a spark plug wire from a spark plug, then put a screwdriver into the spark plug boot against the metal contact for the spark plug, then hold the screwdriver handle with a rubber glove such that the metal for the screwdriver is near a bolt head on the engine, then have an assistant turn over the engine with the key, do you see spark jumping from the screwdriver shaft to the bolt head?
If no spark
Question 3
At the ignition coil, with someone attempting to start the engine with the key, do you have 12.6 V at the positive terminal?
Add the ignition coil, with someone attempting to start the engine with the key, if you put your voltmeter in the Ohms reading position with one lead connected to ignition coil negative and the other connected to battery negative, does continuity turn off and on rapidly?
My guess is that the answer will be no. If so go on to question 4
Question 4 (3-parts) Only applies if you have electronic ignition, see question 1.
Do you have continuity from both wires of the 2-wire connector at the distributor to 2 of the ECU connector wires?
Do you have continuity from one of the ECU connector wires to coil negative?
With key in start position, do you have 12.6V at the last wire to the ECU connector (4-wires total)
If the answer to a question is No, you most likely have a wiring problem to fix.
If the answer to all 3 questions is Yes, I suspect a bad ECU (ignition b
