1989 GMC C2500 Sierra 5.7L Hard start
Posted to GM Driveability on 6/27/2016 12 Replies

This truck will start OK when cold, however once its warm it has a long crank time and then it runs like it was flooded before it clears up. If you start it warm and push the throttle down just a small amount it will fire right away. I don't see anything wrong...
