Why will the starter only click.

The purple wire goes to the starter so far its looking like a bad neutral safety switch.

It looks like a bad neutral safety switch from what you have told me as far as the no power on the purple wire but have it on the yellow wire.

Not if the purple wire at the starter doesnt have power with the key in the start position.

Do you have battery voltage at the purple wire at the starter with the key in the start position?

CAN YOU TURN THE ENGINE'S CRANKSHAFT AT LEAST ONE FULL REVOLUTION BY HAND (WITH A WRENCH OR SOCKET).(TAKE THE KEY COMPLETELY OUT OF THE IGNITION SWITCH BEFORE YOU DO THIS)

THIS IS A TEST TO SEE IF THE ENGINE IS "STUCK", "BINDING" OR "LOCKED UP"

THIS PIC IS OF MY JEEP CJ 5. THE CRANKSHAFT PULLEY IS AT THE BOTTOM OF THE ENGINE. YOURS SHOULD BE SORTA SIMILAR TO MINE

THE MEDIC

Will the engine turn over by hand?

You said you tested the starter at one point how did you test the starter?Also do you have a test light to do some testing?

Do you have a test light to do some checking?

I dont see how thats possible it comes into the neutral safety switch from the ignition on the yellow wire then comes out as the purple wire.

DOES THIS AID YOU IN WHAT'S BEING TESTED?
