3 starters installed on Daewoo Lanos all turn but motor doesn't crank?

Answer 1

starters turn but doesnt crank? If the starters are turning and engaging they will at leat be turning the flywheel, unless there is tooth damage. try to rock the vehicle in gear to test. look at bottom pulley (where the belts are) to see if crank is turning, both when starter is turned and when rocked in gear, this will at least tell you that the flywheel is attached to the crankshaft, and if it turns off the starter motor it also shows the starter motor is working correctly. If this is turning via the starter motor the next thing i would check it the timing/cam belt. behind the plastic cover behind all the belts, especially if the engine is turning fast, wirring and not making the usual chug chug chug starter noise!
