CO Springs aka where HELL froze over!
so my truck wont start.... it started doing this a few days ago... i would turn the key, hear the starter spinning.... but thats it... its like the gears arnt touching inside... so i get under it give it a few love taps then BAM! it works.... started doing it bad yesterday like every time i started the truck i had to get under and do it. After paying more attention under the truck i notice one of the starter bolts is backed out... yet it is completely tightened on... so back it out add a few washers and im thinking this will solve my problem... it did tell today... its back to spinning again and i tried tapping starter and still nothing...wtf is going on!!! btw the starter looks brand new ( i just got the truck last week)
 
If it's spinning without engaging it's either not installed correctly or the solenoid is not pushing the throw-out well enough.

Does this happen more often when the engine is hot?
 
no its pretty much all the time... i wouldn't doubt its installed wrong the guy i got the truck from is a hack. I'm finding more and more ghetto **** on this truck all the time...and its sad to say the guy i got it from is an army mechanic to lol.
 
if its spinning,the starter sound like the solenoid is stuck.pull the starter and check the wiring and see what he did.
 
I had the pin that holds the fork to engage the starter drive back out on mine....cheapo re-man I guess. I pulled the starter and took it apart, replaced the drive, secured the pin, good to go.
 
You could also have a flaky starter drive (sometimes called a bendix). It is a one-way clutch that prevents the engine from spinning the starter when it starts. When they go bad they slip both ways instead of just one but will still catch from time to time.
If the gear is throwing out into the flywheel and your starter is spinning but the engine is not, the starter drive is the culprit. Less that $13 fro O’Reallys.

I've had the 2 bolts holding the solenoid to the starter nose loosen and or fall out and cause this also....starter drives often crap out on GM starters and fail to engauge when its below freezing out too,in my experience--more than one truck I had the starter drive was like a thermometer--anything under 30 degrees and it refused to engauge until you trird starting it a dozen or more times...worked fine in warmer weather!..I had to replace them before I got fired for being late for work too many times...
 
Least you dont have my problem. Went out last week to fire up K20, hit the starter and it spun, just didnt kick the motor over. Wtf, crawl under hammer in hand, and the starter is dangling by the positive cable....WTF?!?!? Get to lookin, both starter bolts are on the ground, sans threads, they are still up in the block snapped off......I am dreading removing them.......
 
They actually come out pretty easy. Dont know for sure but, do you have shims in? They tend to let the bolts get loose. Then the starter flops around a little and eventually breaks the bolts. My 6.2 broke the bolts at work on me. I was able to push on the bolts with a finger and spin them out. If not find a left hand drill bit and they will catch and spin right out.
 
On the start of this thread. If the bendix gets oily it wont let the oneway inside it catch. I'd by a new starter. They're cheap. And if one part of it went bad, chances are the rest isnt far behind.
