Re: 69 Engine won't turn Off With Tilt Column
Check that the ignition power wire (pink wire on GM controller) to the ECM is actually getting switched off when you turn off the key.
Using the battery cut off switch to kill the engine may not be a good idea unless that switch is also disconnecting the alternator. Disconnecting the battery while the alternator is still turning will cause voltages upwards of a 100V into the electrical system. It's better to pull the fuse for the fuel pump or ECM to kill the engine.
