Re: Starter or ignition switch
It's either your ignition switch or ignition switch wiring, lines for the starter relay is short circuited at some point and it keeps the starter running, ALSO it might be a stuck starter relay, so it helps changing the starter relay first and then if the problem still exists have the ignition wiring and ignition switch checked.
Hope it helps and comment if you need more advice.

Sounds like the starter solenoid went out. Watch this video to figure out where the starter is. Take off the battery terminals and take a hammer and hit the starter a few times (not too hard). Sometimes this fixes the problems (parts get stuck once they start getting old). If this doesn't fix it, you'll need to replace the starter.
Change the actual ignition switch? Test light at starter signal wire while someone turns key to see if you have power at signal wire. Check all your grounds after that. Still nothing take steering column apart and change ignition switch .
COULD BE FAULTY STARTER SOLENOID OR STARTER. CHECK THEFT DETERRENT RELAY.SCAN WITH CODE SCANNER FOR THEFT SECURITY TROUBLE CODES.IF ALL IS GOOD.SHIFT TRANSMISSION IN NEUTRAL SEE IF IT WILL CRANK.FAULTY NEUTRAL SWITCH WILL CAUSE NO START PROBLEMS.
Hi, this is what you should do when your car won't start. Diagnosing a no-start condition requires a logical approach to figuring out what might be preventing your car from starting. First, if the engine won't even crank over when you turn the ignition to START, your car obviously won't start. When you turn the ignition key to start your car, voltage from the battery flows through the ignition switch to the Park/Neutral safety switch and/or brake pedal or clutch pedal safety switch (you have to push the pedal down before the circuit will complete) to the starter relay or solenoid. When the relay or solenoid is energized by voltage from the ignition switch circuit, it closes a contact that routes more power from the battery directly to the starter to crank the engine. The starter motor spins, pushes the starter drive gear to engage the flywheel and cranks the engine.
If the engine fails to crank, there is a fault in one of the components in the battery/ignition/starter circuit. Check it out.....
Low battery (Check battery voltage, recharge if low, or jump start with another vehicle or battery charger).
Loose or corroded battery cables (Inspect, clean and tighten BOTH ends of BOTH battery cables).
Bad starter relay wiring connections or ground connection (Inspect, clean, tighten wiring connections).
Bad starter relay/solenoid (Check for voltage at relay, if relay has voltage but there is no "click" when key is turned to start, replace relay).
Bad starter (Jump battery voltage direct to starter to see if it spins, or remove starter and have it bench tested at auto parts store).
Damaged starter drive or teeth on flywheel (Remove starter and inspect drive gear and flywheel teeth, replace damaged parts if necessary).
Bad ignition switch (Check to see if voltage reaches starter relay/solenoid when turn to start. If not, check for open P/N switch and brake or clutch pedal switch. Replace ignition switch if defective).
Open P/N safety switch, or open Brake Pedal Safety Switch (automatic transmission) or open Clutch Pedal Switch (manual transmission). Bypass switch with jumper wire to see if engine cranks, or use test light or voltmeter to check for voltage passing through switch when ignition is turned to start.
Engine seized due to bearing failure or internal damage (Use socket and long handle to see if engine can be turned by hand, if not engine is locked up).
Engine hydrolocked due to coolant leak from leaky head gasket (Use socket and wrench to see if engine rotates, remove spark plugs and see if coolant comes out or engine can not be cranked with plugs out).
no fuse for starter. starter gets permanent battery voltage on large terminal[8mm stud] on starter solenoid. activated by voltage to small terminal on solenoid via ignition switch.check if starter gets voltage on small terminal when ignition in cranking position. if not fault with ignition switch or wiring. if yes fault with starter. also check that starter has good earth connection with battery
The ignition switch can be just an SPST toggle switch that connects power from the battery side of the starter solenoid to the battery side of the ignition resistor. The starter switch is just a normally-open single-pole push-button. The starter solenoid usually has two small terminals and two large terminals. Wire one small terminal to the battery side of the solenoid and the other small terminal to the starter switch. The other side of the starter switch goes to a good grounding point. This allows the starter to be operated at any time whether the ignition is on or not. Remove a battery terminal to prevent kids from starting the car or turning the ignition on and running the battery down. Hope this helps!
this is hard to do, i dont have the year,model or engine. but i can give you a few things to check, the first most common is the cable going to starter, the connection at starter from this cable rots inside that terminal, it starts when ever it wants, next is the starter it self,when it doesnt start have someone hold the key in crank, while you test both wires at starter, this you condem or pass the starter, and the last would be the neutral saftey switch if theres no power to small wire on starter with key in crank then check the neutral safty switch. hope this helps,
make sure you have power to the b+ terminal of starter. Also make sure you got power to the ignition terminal on starter with key in the crank possition. With key in the crank possition check that power is being tranfered from solenoid to motor. If all these check ok replace starter. If no power in the ign(small gage wire on starter) possible ignition switch or p/n safety switch. If no powere on B+ check battery, battery cablem fusible link.
The problem is either the starter solinoid (located on fender near battery) or you are not getting power to the "s" terminal on the starter solinoid from the ignition switch. If you follow the positive battery cable from the battery you'll follow it to the solinoid. Remove the small wire from the terminal marked "s" on the solinoid and using a screwdriver jump from "s" terminal (not the wire) to where positive battery cable connects to solinoid. (with battery connected). If starter doesn't do anything the solinoid is bad. If starter cranks then you are not getting voltage from ignition switch through "s" terminal wire.
