Need help with no spark

To get started, make a few tests..........

With everything hooked up "normal" turn key to run

Measure power on both sides of ballast. "Key" side should be "same as battery" and coil side should be somewhat lower perhaps 8V

Measure power at coil NEG. Should be quite low, 1V or so

Wiggle and work the dist. connector in/ out several times

Make CERTAIN and I mean CERTAIN that the ECU is grounded.

Hook the disconnected distributor connector..........the dist end....to your voltmeter on low volts AC. That's right, AC. Crank the engine. It should produce about 1V AC

Remove cap and examine internally for junk, rust debri, or strike damage to reluctor

Get a brass feeler and measure reluctor to pickup gap, .008". That's inches, not metric

Turn the key to run. Hold the coil HT wire near ground. Separate the distributor connector, and take up the vehicle side (not the dist end). "Tap" the bare connector terminal to ground. You should get one spark "snap" each time

Disconnect "everything" to coil except coil + and NEG wires, unhook tach, radio condenser
