Re: Having problems starting after replacing starter solenoid

Even if the switch has been bypassed, the jumper or splice that was used to bypass it might have come unhooked. Look under the dash near the steering column for two 12ga purple wires that go to the safety switch (or have been spliced together). One of the wires might be yellow instead of purple ... GM changed some of the color codes during '78.

If that switch (or the bypass) is good, but you still don't have power on those wires in the "start" position, it could be a bad ignition switch.
Wow thanks for the info! Ill take a look at the solenoid wire first to see if thats ok. My father believes its the clutch safety switch, and you said that can be found under the dash right? or is it just the wires that go to the clutch safety switch?
