Starter or something else
 

I have a 97 sable with 103k miles. I have replaced the alternator, battery, and ignition coil in the last year.

Just recently, I have encountered a problem where the starter makes a momentary scraping sound when I start the engine.

It does not do this all the time.

Could it be the starter on its way or something else like a relay not delivering all the voltage?

Thoughts? Thanks.
