    69 BB Car won't crank

    I have a 69 corvette BB, 4 speed car. I took the dash and started to put the dash back in.. I had also had changed the vacuum power booster at the same time. After installing the dash pad, I was checking the lights on speedo/tach pad to see if everything was correct. I was curious and wanted to crank the motor but nothing!!!!. I


    I was curious, as i was under the dash, I saw a rod that was hanging all by itself as it looked like it was coming off the clutch pedal. Is the safety neutral switch the driver side dash? If so where is it? Does that rod get hooked to that switch? Is that why possibly the car is not cranking over?

    Your thoughts appreciated

    Mark, have you driven the car, does the clutch pedal have to be depressed before the car will fire? My 90 requires
    the clutch to be depressed. If you have a copy of the assembly manual it will show how it is attached. Good luck.

        Your car has a clutch safety switch which is connected to the clutch pedal via a lever. It's normally electrically open, and closes to permit starter operation when the clutch is depressed. You may be onto the problem with the loose rod.

          Mark, yes you are correct, when i changed my brake booster, It must of came off and didn't realize until now. I installed and it turned over to start.

          Thanks everybody
