Hope someone can help me. I have a '87 MAF on a 383 I built and have it in a '41 Chevy coupe.Just about done with this project after 2 years of doing a frame off. Her's my problem(s). With the timing bypass wire disconnected, car will start and run. Timing set to 6*. When I connect the bypass wire, car won't start. Timing stays at 6* while cranking, so it's not being retarded by the ECM. It wants to start, and does momentarily, but as soon as you let go of the key it quits. There is no solonoid or resistor in the system.(like the old ones that wouldn't start if you had a bad resistor)
Anyone have any ideas? I seem to remember seeing something like this on this thread a while ago, but can't find it now. Would really like to get this finished and on the road this summer. Would a bad or wrong CTS cause this?
