I retested with the connector attached and got what I think is a good result..maybe.

The Crank test yielded a perfect blinking light from the LED.

The Cam Sensor test yielded a blinking light, but it was faster and irregular. At first I thought this was the culprit, but now I think it may be that the LED can't keep up with the high frequency signal. Anyone concur? Or should I go on with dizzy swap?

Despite FE's excellent description of how to swap out the dizzy, I'm still hesitant. If the sensor test was definitive then I'd already be tearing into it. But having never done it I'm sure I'll find a way to screw it up. Then I'm troubleshooting 2 problems at once.

Does anyone have any input here?

Is it possible that ignition and fuel system are not the problem? What other system could I check? I'm at the end of the road here. After dizzy swap I'm out of ideas.

Hell everything is testing fine. Maybe the thing is fine. Maybe its my imagination Maybe I should stop being so picky and just push it to work and back...

I'm soooo close to putting this f*cker up for sale. So close.
