My car is stuck on. It has a vacuum leak and we have been popping the hood to get it started. No the hood latch must have gone bad because it wont pop open and the car is stuck on. How do I shut it off?

Vacuum has nothing to do with it not starting, that's an electrical issue.

Remove the drivers side knee panel.
Look for a brown vacuum line coming from the keyswitch.
Detach it and either use a mityvac or suck on the tube to shut it off.

It's not pretty, but it will work until you can fix the hood cable.

Hopefully the shutoff valve isn't bad, then you'd be in real trouble.

You say you have a vacuum leak...unless it was a really big leak, the car would still probably shut off with the key. I don't know if the shutoff vacuum is drawn off of the accessory vacuum system or the line going to the brake booster on your car. Mine comes off the brake booster line, and I would think one would have to have a really big leak somewhere to affect that. And then the brakes would probably be pretty bad. It would help to know what car you have.

If the shutoff valve is bad, you could climb under the car and disconnect the fuel lines and just wait for it to die. Make sure the return line stays hooked up. It could take a while to use up all that fuel, but it will eventually kill it. Starting it up would prove to me a pain in the butt the next time however

It is still running. The vac leak must be under the hood. Ho w do I release the latch. It is an 84 300D.

On our 300D the hood "sticks" try having someone pull up on the hood when you pull the release lever, I bet it will pop up.
