COPO Chevelle start/run problems

[Keith Tedford]

When our '69 el Camino did that, in our case, the cure was to replace the ignition switch down near the firewall on top of the steering column. The old wiring could be the problem too and you can give it a good check when you have things apart. Changing out the switch isn't that much of a job. A whole new harness is good fire insurance in these old cars.
