you must have a short in which the starter is connected directly to the battery in 1 way or another
Stuck relay or the starter is wired incorrectly.
Had same problem with My 91 Lumina APV. Changed Starter Relay. Haven't had any problems sence.
must install a cut off relay in the system
your batterie, the pos. cable run to a relay then to the starter. its called a starter relay its usually an the same side as the batt. on the fender, follow your batt. cables
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.
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.
Relay is stuck.
If you mean that the starter keeps spinning after the vehicle starts), the solenoid/relay switch is not releasing. In the START position, the relay spins the starter to start the engine and should release when the key is moved from START to RUN. Probably needs to be cleaned or replaced.
That is a tell tell sign that your problem is eletrical. Mabey a bad relay
A fuel pump relay provides power to turn on fuel pump. A relay allows small current to control high current- example- a starter relay-- If you didnt have a starter relay- the big thick starter wires would have to run to the ignition switch, and then back to the starter. with a relay- you only have little tiny wires running to the ignition switch... when you turn the ignition switch on, a little bit of current goes through the tiny wires to the relay- which powers a coil- which then makes the contacts inside the relay connect- which then allows the high current to run through the big wires to the starter. kinda simple- but can be confusing. carmine C-
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.
might be starter relay, or the crank circuitry from the switch or to the starter from the relay. I would trace back from the starter to the starter relay back through the neutral safety switch to the ignition switch.
