Thanks LR! I agree...I think! What confuses me is the fact that I have control voltage going into the PT, yet nothing coming out of the coil secondary. I thought the pulsing control voltage (5v--open--5V--open...etc) was what made the coil set the spark in motion. If I'm getting pulsing 5V at the PT, and the PT is known good, shouldn't the coil be putting something out? I put a spark plug checker inline between the coil secondary and the dizzy center input and saw nothing. Confused. Is there a second event that occurs at the PT that could be absent and thus keeping the coil from doing its job?

Also, I have already swapped in Hazy's known good complete dizzy and am seeing no change. It (like the old one) passes all the troubleshooting tests. So there IS signal coming from the dizzy sensors, but the DASH TACH (and thus ECU?)is not seeing anything.

I'm going to go check the ignition switch per Dave's tip (Thanks Dave!). I'll report back.

So at this point it is looking like its either the ignition switch or a bad connector or wire somewhere between the dizzy sensors and the ecu. That sound reasonable? I think we've tested all the individual ignition components at this point.

Well...we haven't formally tested the Control Relay, though I visually inspected it (it was pristine inside) and I can hear it clicking when I turn the ignition.

Sorry for rambling. I'm recapping for my own benefit and also in hopes someone will see something in all that...

Thanks again. Off to the driveway.
