Re: COPO Chevelle start/run problems
Is the ignition key switch in the column the original or a new one? (the new ones are notorious for being faulty - like the one i got that had no accessory position).
If this was a mopar, the culprit would be a burned out ballast resistor on the firewall. Does your wiring harness have a ballast wire or a firewall mounted resistor? The ballast wire could have broken at the terminal connection to the coil.

Re: COPO Chevelle start/run problems
In my youth (16ish) my 66 chevy II had some extra wire in the firewall gutter. so being the "smart guy" [img]<<GRAEMLIN_URL>>/crazy.gif[/img] I shortened it up to a respectable length so it was not doubled up in that gutter. Result was same problem "would start but not run".. Installed ballast resistor with some advice from experienced mech, and learned something about automotive electrics. [img]<<GRAEMLIN_URL>>/scholar.gif[/img] Sounds like Steve is pointing in the right direction. Dicky [img]<<GRAEMLIN_URL>>/flag.gif[/img]

Re: COPO Chevelle start/run problems
That happened to my early corvette. Replaced the ignition switch and it was solved. Maybe your wires at the switch are loose?
