Re: motor wont turn over

Is it seized?
Remove the spark plugs and try to rotate the flywheel by hand, will it rotate?

Re: motor wont turn over

its not seized cause i could turn flywheel by hand starter is not engaging to turn motor.i put another bendix from another starter and a second hand starter solinoid.im wondering if wires or right.

Re: motor wont turn over

does the starter do ant thing when you turn the key.....try to turn at all..if not check your in line fuse see if its blown....its goes to the solenoid.....if good clean all the connections....from battery to starter....

try jumping the starter....hook jumpers to the pos stud and engine ground and then to battery...see if it spins....

from solinoid to wire harness?
