93 STS - Starter stays ON continuosly...


Recommended Posts

Hi gents. Just replaced my starter in my 93 STS. Wasn't too hard. Just time consuming. Cleaned all the gunk out of everything under there including the spacer plates. Thorough job. Was pretty proud of my work. Clean as a whistle. 17 years of gunk removed.

I put a new battery in. Cranked it up and the motor was turning over, but not firing. Minor triumph. Has sat for quite some time, so I figured it was a fuel problem. I cranked it about 7 times hoping to get some fuel up the motor. It just wouldn't fire. BUT at the very end, the starter just stayed ON! I could hear it spinning. Not good. I unhooked the batt.

Why is this? Anyone seen a stuck ON starter before?? Remedy? Thank you in advance.

Something is odd with that, the solenoid engages the starter drive into the flywheel, the solenoid also acts as a switch at maximum starter drive throw, so what you are describing seems impossible,

Are you sure the starter motor is spinning but not turning the engine?

I have never seen this happen

I am fairly sure it's just the starter motor spinning. It's a quiet whine that doesn't sound like when I was turning the key and cranking the motor.

I guess the starter failed/heated up/ melted something with the constant cranking when I first started it up?

Looks like I will take it apart again and take the starter back for testing and possibly another one. :-(

It sounds like the solenoid is shot. Return that POS starter to Checker, get your money back and then buy an AC Delco starter. The AC Delco is the OEM replacement for your car. Check gmotors.com for discounts on OEM parts. The problem with "lifetime" parts from the huge auto parts stores is that you will be replacing them for the rest of your lifetime...

I think we need to register your QUOTE Kevin, it reminds me of this quote from a rather famous philosopher

A good decision is based on knowledge and not on numbers.
