With a voltmeter, check for battery voltage at the ckp connector disconnected from the ckp with the key on eng off. It should be close to battery voltage, but not necessarily exactly the same. If that's good, then switch your meter to AC volts and connect to the back two connections on the ckp sensor. Then rotate the crankshaft with a socket wrench etc. If working, you will see voltage pulses as the gear toothed ring turns past the sensor. No pulse means the ckp is no good. Hope that helps.

Just curious... how do you know that it is not working?

did you put the taper or slope that is on the end the same way as the one you replaced? if it is backwards then it ain't gonna sense anything. also just because it is a new one does not mean it is good. there are bad ones sold everyday.
