70 GTX won't start after conversion #670735 04/15/10 04:13 PM 04/15/10 04:13 PM

I know there are no issues with the engine wiring harness and the control module, ballast resister, and coil are new but it appears there is no spark from the coil. The distributor was changed to a Mallory unilite from the old points distributor. I had to put a mopar 2 prong connector on it for the wiring harness to plug in and the third wire from the unilite was grounded to the block. I did have to replace the wires under the dash that run from the bulkhead to the ammeter. The dash is out but I have hooked all the power wires together. Can anyone give me some suggestions on where to look and tell me what I can check with a meter? Thanks, Todd

The mallory unilite distributor that I put in the car for the conversion came with the car in a box and is used but nice looking. I have not heard a motor run with this distributor. Is there a way to test a Unilite distributor to see if it's good?

So I guess my two options are to modify the new wiring harness (I don't want to do this to a new engine harness) or use a different distributor with a magnetic pick-up. Does this info sound accurate? Can anyone recommend a good distributor that uses a magnetic pick-up for a performance engine? Thanks, Todd

The MP (Mallory) ones, the easily adjustable mech adv feature is nice. No opinion on their quality (havent seen/used one). Might see what FBO has to offer live every 24 hour block of time like it's your last day on earth
