New owner of a 97 Blazer with 130K on the mileage, got from a family member w/c he bought new. Bear with me on describing the issue, the whole starter was replaced 5 months ago now I have this weird starter issues, the truck starts basically ok but when the engine starts running you could hear this like backfiring sound on the starter area, checked on the engine itself the engine purring like a cat no misfiring or rough idle, when you turn off the ignition you could hear this loud whining or dynamosound on the starter itself w/c itstogauge it1 to 10 it's 7. It doesn't stop until you remove the battery connection and smells like burned thing after, when you start it again it starts normally but then again the whining sound and misfiring like sound.Any advice would be greatly appreciated. Thanks in advance!

 

Since you did not replace the starter yourself take it back to the person/shop who did. It might not be properly adjusted/shimmed, causing the starter drive to not compeletly disengage from the flywheel/flexplate. If this goes on for a long time then you will have to drop the tranny and replace the flywheel/flexplate and get new starter since the starter drive gear would be destroyed by excessive RPM's...

 

I think that's the logical thing to do bring it back. Just for curiosity if the starter then wasn't properly adjusted or shimmed would it be the problem existed sooner? This just happened yesterday so when we heard the sound parked the truck and didn't use it so not to cause more damage.
