Sounds like the starter solenoid is sticking, could be faulty. You might have to pull it out and bench test it. First put a multimeter or test light on the starter solenoid wire (without it being connected to the starter) and check that it stops supplying power when you switch the key off to make sure you don't have any wiring issues.
yes, it happened to me, what it was, the solenoid of the starter motor got stucked at the closed position causing it to continue working even doe the ingnition key was removed. yes, it happened to me, what it was, the solenoid of the starter motor got stucked at the closed position causing it to continue working even doe the ingnition key was removed.
replace ignition switch
A 1986 Ford F150 starter won't stuff off when the key is turned off if the ignition switch is jammed. This will cause the start signal to be sent to the starter continuously.
It is probably caused by the ignition switch internals shifting (I had a similar problem before) and it turned out to be the ignition switch)
It sounds like the solenoid is stuck. does the car have an aftermarket remote starter? it could be malfunctioning. ive never seen a solenoid stick on one of these.
If there is complete silence when the key is turned, try tapping the solenoid on the starter with a hammer. Don't laugh. I have found this to be the solution in several cases. This is sure proof that the starter solenoid is the problem. You will want to install a new starter which comes with a new solenoid before you get stranded.
ignition or starter or both.
It could be starter, battery, keyswitch, neutral lockout switch or electrical connections.
If you mean the relay that controls the starter motor then it is fairly simple. There are 2 possible faults. 1) The relay is working, but is broken or burned out internally. You will hear a click from the engine bay when the key is turned but the starter motor will not do anything, not even engage. 2) The relay is broken. In this case nothing at all will happen when the key is turned.
Someone tells me this could be to do with the starter motor
Defective ignition switch, or bad starter.
The 1991 Ford Explorer should have a separate starter relay that sends power to the starter. It sounds like the relay has stuck and is sending power to the starter even after the vehicle is running.
