Bad ignition switch. This is one of the problems experienced by many classic Mustang owners. The problem also has occured in reverse, ignition switch is on and the engine just simply dies. I usually keep a spare ignition switch (a used one which I know works to trobleshoot should the problem arise) and a new one to quickly replace the bad one since they are fairly inexpensive.
not turning on could be flat battery, bad igniton switch, bad safety switch, bad starter motor,bad stater solenoid
The signal for the starter originates from the key switch, I would start there.
Either the starter, starter relay or ignition switch are failing.
By passkey. If you are talking about a starter by-pass. It is not keyed, but a push button on & off switch. You must break the small wire at the starter relay, or solenoid, and wire the switch in series. After the car starts, you must release the push on/off switch, or you will keep turning the starter motor.
Sounds like the starter solenoid is stuck. Another possibility is the ignition key switch is not automatically returning from the start to run position. As the switches get older they seem to get stiff. Could be a weak spring in the switch or just gummed up lubricant. The easy test is to try turning the key counter clockwise after starting the engine and see if the starter motor stops running.
Not only would the safety switch keep the engine from starting up, the starter would make no attempt to crank the engine over.
Probably not a bad ignition switch, but more likely a bad starter solenoid. It takes a lot of current to get a starter to turn, to much to go through such a small switch like the ignition switch. The ignition switch actually controls a relay(solenoid) which can handle the needed current to get the starter going. On a lot of modern cars the solenoid is built into the starter unlike older cars and trucks where it was mounted on the firewall between the battery and the starter.
I had a 96 Stratus that would do that, and it turned out to be that the starter was bad.
it could most likely be ur ignition switch it cant be starter...
you need to have ignition switch checked,if switch is good then you need to replace starter motor. a bad ford starter will keep draawing power regardless of key being on or not
Sounds like the solenoid on top of the starter is bad. If the plunger return spring is broken, the starter stays engaged all the time.
I suspect the switch is bad.
