car starts when i turn switch to on position

Post by methos76 » Fri May 17, 2019 6:28 pm

can anyone help I went out and started my 66 t-bird was sitting idling, I was in the middle of putting down the passenger window when the starter engaged and wouldn't disengage until I shut switch off. now when I turn the switch on the car cranks and starts but the starter is still engaged, I beat on the fuse box and turned the switch back on and it was alright for about 3 seconds then it starts cranking on its own. ive replaced the solenoid but same thing. any clues

Replace the ignition switch.
My issue was similar in that i would start the car but the starter motor would keep spinning while the engine was running and when i switched it off. Had to disconnect the battery each time.
I did replace the starter solenoid three times before i figured out it was the ignition switch.

thank you I will check it out. I don't have to try to start it, all I have to do is turn the switch to the on position not the start position and it starts cranking

You could have the Start and Ignition wires reversed on the solinoid.

the wires have been hooked up the way they are for the last year and today is the first time its ever done that, ive been told its the switch and ive been told it sounds like it lost a ground so I have some checking to do

I don't know how losing a ground would cause that. More likely just a wonky switch.

It's pretty simple, but there are a couple of tricks to know. I believe the procedure is outlined in the manual. If you don't have one (yet), this video will give you the basics: https://www.youtube.com/watch?v=tCMLzQaiUB0
