MOTOR Hi I have just put a motor in a 2002 jeep liberty and have changed the crank sensor. I have power going to one side of wires on crank sensor but nothing to the other side, so jeep won't start anyone got any suggestions please?

On the crank sensor you should have a 5 volt reference constant with the key on and on the other wire you will only have a pulse signal(square wave) on a scope. This is the signal back to the pcm for crank reference. If you have a scanner, hook it up and simply check for crank (CKP) signal on the data screen. The common problem after an engine install on this vehicle w/ a 3.7 V6 is the cam sensor gets left unhooked because it is hard to see on the right head and the wire gets hidden.

Hope this helps..
