Yeah, same car again. '75 duster with '76 400 big block, 727 auto trans, older 8.75" rear. Thought I just about had it in running order but it has recently developed a problem with either the fuel system or ignition system i think and will not stay running. It started probably a few months ago, only did it once in a while back then, now does it every time I try to start it. The car will fire up and run good for a few minutes then starts misfiring real bad then dies. Hard to start after that but will start then dies again. I suspected the fuel system at first, so I wrapped the fuel lines to make sure they weren't getting hot causing a vapor lock situation. Also pulled the fuel line off the carb when she quit and liquid fuel came out. Pump has good pressure, fuel filter is clean. The distributor is new as of a year ago, and I replaced the coil and the ballast resistor and the plugs and wires since the problem started and it hasn't helped. The battery is new within the last year as well. The engine has two ground straps, so I assume that is not the problem. The ignition control module is not stock; it is an ancient GP Sorenson module on the driver's side fender. I traced the wires to figure out where eveything is going and checked for continuity through the module, the hot and ground wires to the coil, the hot and ground wires to the pickup coil, and through the coil itself. Everything checks out, but the problem persists. I am out of ideas; can someone help me?
