Ok guys I'm at my wits end with this thing. Long story short, buddy is getting divorced and selling his project but I told him I would at least get it running to net him some extra money. I should have listened when he said it was a lost cause Anyway it's a 73 road runner with the 440 and auto transmission. Everything in the ignition is new. 4 prong ignition control module, 2 prong resister ballist, voltage regulator, accel coil, distributer, cap, rotor, plugs, wires, and it has no spark or maybe every 4-5 seconds of cranking I'll get a faint glow on the spark tester light. Bypassed the whole car and ran a 12v wire to the register ballist positive end and still nothing. Ran direct ground to the back of the Igniton control module to the negative and still not vroom vroom. Coil is getting power, all wires have continuity, distributer was picking up the gear and sending a feed to the igniton module. I'm so stumped. I'm not good with old cars but I've been reading and testing threads on every forum site and I just cant get it to spark. Please send your thoughts. I want to try to get this running before he sells this ole girl for less than he deserves. I'm picking it up tomorrow (Jan 5th 2019) and bringing it to my garage to work on it more.
