Corvette won't shut off! HELP
I have been working on this 1969 350cc and today we advanced the timing a little, the car eventually stalled and when it did it kept turning slowly as if it was diesling, but without much noise. We shut off the ignition and it kept doing it, and then when it stopped there was no power. We disconnected the battery (terminals were hot) and reconnected it and now we have power again, but it won't shut off with the key any more. We disconnected the steering column harness and it still has power when we re-connect the battery cables. I am assuming there is a relay of some sorts (maybe on the solenoid?) and this has gone bad. I would appreciate any help anyone has to offer. Thanks!! :confused: :confused: :confused:

Run on: too low of octane / motor is very hot / spark plug is too hot / timing is too far advanced / timing is wrong due to improper cam installation / timing is wrong due to timing chain jumping teeth / idle speed is too high. Take your pick. I can probably think of more.

Re: Corvette won't shut off! HELP (63Banshee)
I'm sure it probably from the timing, but what caused the power to stay on even with the key off? Was this related or was it just a coincedence? And what could cause this? Thanks!! :confused: :confused: :confused:

Re: Corvette won't shut off! HELP (JoeMacgruder)
I've seen this happen from a sticking starter solenoid keeping the starter connected to the battery, and thus keeping power going to the ignition. It sometimes reveals itself when setting the timing too advanced cause it will result in a larger kick back when starting and more prone to lock in place.
Replace the starter, it may just be the solenoid, but if the solenoid locked up then the starter was connected spinning along with the flywheel while the engine was running...kind of causes sever wear in the starter itself.

Joe... we are all just pyssin in the wind unless we know if your engine kept running due to the ignition not shutting off, or if it was "dieseling" or experiencing "run-on".
They are two entirely different problems... that is why the first posts listed a bunch of possible causes.
Was the starter engaged while the engine was running?
Was the engine actually "running", or was it just "kicking over" and sputtering?
The problem cannot be diagnosed properly unless you first determine which condition exists.

Tom.. The starter was not engaged when the engine was running (not at least that I could hear). The engine was actually running and then began to die when the problem began. The engine didn't sound like it was diesling as much as it was being pushed by a high compression. And I attempted to shut it off by turning off the ignition at the key, but the key wouldn't shut it off at that point. Now the key doesn't work at all electrically, the car has full power whether the key is on or off.
