Car runs great, but wont turn off!

Hey fellas.

 

So, when I turn the key to shut the ignition off nothing happens. The key turns just fine, however the engine continues to run, I have to disconnect the battery to shut her off. Any ideas?

 

 

Cheers...

replace your ignition switch

check your dist. wiring if it is run to the alternator then power will continue even though the ignition is off.

If the starter solenoid is sticking (micro welding), then you likely have excessive current draw to the starter from either a bad starter, or bad cables so check those also.

On my 70 the pin that is in the picture came out and the car would not shut off.

I picked up a new ignition switch today, if that doesnt cure it I will take a look at the starter solenoid.

Did the swap over to the new ignition cylinder, now I have no power at all to anything. The battery has charge but the entire system is dead.

All fixed...Thanks guys!

What fixed it?.

Wow Rick- that is an interesting find and fix about that little pin that was preventing the car from shutting off. What is it's function? Was it providing sound ground path or something?

It is part of the ignition on a 70. As you turn the key on it ingages the ignition switch. When the pin came out the key turned off but the ignition was still on. I got lucky when i found this problem. The ignition is totally different on a 69. I hope this explained it.

Interesting. Sounds like a mechanical linkage that has to push and pull on a shaft or rod or something. Maybe "push to run" and "pull to off". If you get it in run, and the pin came out, then can't "pull" the ignition off. something like that.... 69's had ignition on the dash so wouldn't be anything like that. Must be a first design feature for this first "ignition on the tree" for mustangs. interesting.
