Electronic Ignition Problems - Help!

Hello,

I have a 1983 F100 with a 302 and automatic transmission. Previous owner installed an electronic ignition. The problem I am having is that I am getting backfires and really no power. Mostly happens right after I start the truck. I think the backfire and no power is because the electronic ignition has a problem. I can get the truck to run fine if I shut it off, coast, and then re-start it.

I pulled the distributor cap and cleaned it. The only other thing that looks different is that the coil appears to be stock.

Any help would be greatly appreciated.

Thanks

Kevin

Brand

I am having trouble figuring out the make of the system. When I pulled the distributor cap I saw what is a round series of magnets. The other thing is that the base (right below the cap) has a square part that bulges out. I don't think it is a Petronix or MSD.

Your description sounds like you have the later-model stock TFI ignition, where the ignition module is bolted to the side of the distributor.

Does your distributor have a vacuum advance canister with a vacuum hose connected to it?
