i have a 99 k2500 and over the last 3 months i put 5 starters, 2 flex platesand a distributor drive gears in it. everytime it gets cold outside, the truck doesnt want to start. i have also replaced a battery and the ground cable to the starter and the body. when you go to start it, it trys to start then the flexplate and the starter bind and make loud horriable noises. can someone help me out?? i have put almost 2000 into this please help!!!!

 

You might be missing the appropriate shims for the starter.

 

i had someone shim it out and it ran for a week or 2 then wouldnt start again. and it sounds just like it did before.

 

It sounds like you may have a wonky starter.
