64 Belvedere 400ci, electronic ignition conversion, Comp Cam, ran 2 months ago when backed into the garage. I did some rewiring following the schematics for the car and the ignition conversion. Put a balast resistor back on and a mopar voltage regulator. All voltages check out ok. 8 volts at coil when key on, 12+ when cranking. Brand new Holley 650 DP out of the box, New plugs, Distibutor not disturbed. Now I can't get the car to run. It turns over and fires on a cylinder or 2 then dies and belches flames out the carb. Tried the previous running carb and nothing. No change. 2 sets of plugs, 3 balast resistors, No ideas. I'm completely stumped. Everything has been triple checked.
 
Sounds like 180 off on the distributer.Must of had to disturb it some to to convert it?
 
Nope. The car already had the electronic ignition in it. I just replaced the harness from the orange box out. Never touched the dizzy except to plug it in. The car had a GM alternator, and the balast resistor and regulator had been removed when I bought it. The ignition start and run wires had also been joined together. The car was burning out coils including a brand new MSD blaster that I put on it. It is all back to Chrysler specs. That's the weird part. The Dizzy was never moved. Could a change in Voltage to the dizzy affect the timing?
 
Yep. They weren't disturbed from when the car was shut off in May. That's the frustrating part. The car ran fine with a messy fire hazard of an engine wiring harness, but now that it's been cleaned up or replaced with new stock and had everything tested the damn car won't run. Gonna rest the initial timing for start up and work from there and see what happens.
 
Ok so Everything checks out to the distributor end of the coil wire. Lots of bright blue spark until its plugged into the distributor cap. Then nothing. 3 differnet caps, 2 rotor buttons made no difference. Any ideas?

What about the coil cable to the distributor ?
 
That's next. Gotta be it. Everything else has been changed at least once. We were going to try that, then I goofed and shorted the trigger wires to the starter and they burned up..literally. Gotta replace a couple of wires before trying again.

Sounds like the 2 wires to the distributor are reversed. If the wires to the distributor are reversed the timing will be about 35 degrees to much advanced and you will have those exact symptoms. If you just retard the timing with the distributor, the rotor phasing is then all screwed up so don't do that. Try to fire the engine with someone holding the timing light watching the timing, if the light shows no timing marks at all or way advanced, switch the wires to the distributor.
 
Those wires come from the factory harness. into the factory connector for the distributor. They shouldn't be backwards I wouldn't think but it's something I'll check. I'm open to all suggestions. Thanks.
