I had gotten a Petronix electronic ignition module (1847V). Prior to installing it, the car had been running great with the points (I know, should have left well enough alone). I installed it per the instructions and cranked the motor over but nothing. I checked all my connections and cranked it over again and nothing. So I removed it and put the points back on.

When I go to start it, it seems that only 2 of the cylinders are firing. It was definitely idling low. My CHT gauge never really moved (it's on #3) so I suspect that 3 and possibly 4 are not firing. I drove it about 1/4 mile and no power.

Could I have flooded 3 and 4 when I had the Petronix unit on? I'm going to let the car sit overnight and try it again in the morning. Could I have damaged something with the Petronix unit?

Major mystery ...

I will start by saying that changing components will change the timing. It is feasible that the Petronix threw the timing off far enough that the engine wouldn't start. There is nothing to guarantee that when you slipped the magnet over the point cam that the magnets lined up with the sensor in the same manner that the points were aligned for firing (my conjecture).

If this were true, the engine started and ran, alebit badly, you could have filled the cylinders with enough fuel to drown out the fire. I would think if all things were correct they should have cleared themselves.

Since the L-Jet takes the signal from the points/coil circuit for firing of the injectors I also wonder if the P unit did something to the brain if the P unit was defective out of the box

All this says is that I really have no answer, but I would check the timing of the engine for sure.
