Default Faulty starter solenoid??

So the starter (or solenoid)in my wifes car has been funky since i purchased it (about 3 months ago). It would just click and eventually turn the engine over. Just yesterday i replaced the spark plugs. It seemed to start a lot quicker (withing about a second of the engine turning over)with the new Bosch Platinum plugs. I think thisis where the issue has comefrom. The car is a 1997, all origional starter parts. After replacing the plugs, i started it up,and it made a horrible noise. It was not the pistons hitting theplugs, but it was the starter stillturning after the engine was running! and the starter kept turning even with the key in the off position and they key out! im guessing the starter solenoid has finally met its match and has gotten stuck and kept the starter engaged. i unhooked the battery as it was the only way to shut it all off. then i hooked it back up and the starter was cranking again! ***!!?? any ideas or similar assumptions??

Was there still power going to the starter when it was making the grinding sound? There are two possible reasons a starter will do this. The obvious problem is the solenoid, which keeps giving it power. Another problem could be the plunger, which can get stuck, keeping the bendix pinned up against the flywheel. Starter solenoids are cheap, can't hurt to replace it.

the starter still turning while the engine was runiing was the grinding noise. i took a half day from work to replace the solenoid ($80). hopefully that fixes the whole starter issue with the clicking as well as its need to turn on its own lol. if not ill just buy a new starter too ($120) but i feel pretty confident its the solenoid.

really hate to say this but it sounds like a bad spot or short on the commutator, it could be the solenoid- the contact may have gotten so pitted and burned from years of hundreds of amps running though it that it can no longer get a good connection, but i had a dakota with a bad starter and it needed a new starter, it would draw 200amps just clicking- the commutator was shorted.

good luck, i hope its the solenoid!

A bad comm wouldn't cause the starter to stay running or make a constant grinding noise after the engine starts... it would just fail to work.

The engaging pin in the solenoid is sticking. Once it's running, whack it (and/or the starter motor) with a rubber mallet, should cure it at least temporarily. If it sticks again, just replace it. If whacking it makes no difference it may be something else.

Well i took the starter out and made a trip to autozone. they did a bench test and "click". dead. didnt even turn, just clicked. so i just replaced the whole starter. $140, but now it starts right up every time. im pretty sure it was the solenoid, but i believe when it was turning by itself for 5 minutes while i was figuring out how to shut it off, prob burnt up the motor too lol. oh well. alll fixed and good to go now. thanks guys!

I know it can be just the solinoid but my experience (40+ years of fixing my own vehicles) leads me to just replace the entire thing the first time around. I have found that the cost is not all that much greater and I know that I've got a working system - barring getting a bad part that is...

I know the problem is fixed but for anyone else try to replace the contacts and plunger.

For less than $20.00 its a easy fix. Like said above, over the years and the 100's of Amps that pass thru them the contacts do wear out and the plungers can get stuck from all the dust and grime that can make its way inside.
