Hi David, Remove the sensor and hook up an analogue voltmeter to the two cables. Set the meter at mili voltage and pass a metal screw driver across the business end of the sensor, without coming into contact with it. You should have a distance of about 0.5 of a millimeter gap between the sensor and the screw driver. The voltage generated is very small and the pulse will only occur as the field is broken. In other words its a two man job. If the needle of the meter moves the sensor is fine, if not replace it. It is very important to use an analogue meter as the pulse is too small to be noticed on most digital meters. Regards John
If it where the crank sensor there would be no injector pulse also. If it where the cam sensor you could have unplugged it and see if the car started.
I think this one may have a simpler solution. Have you checked for power to the coils? Have you checked the coil fuse or the ECM relay?
spark comes from a couple places you want to check.
2) crank and cam sensor
if you find also the injectors are not getting an injector pulse than your spark problem is leaning more towards the sensors or the ECM.
I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.
cam sensor fires the injectors to synchronise injector pulsing with the spark at the spark plugs.. U need to probably change the crankshaft sensor (around the crank pulley) as the crank sensor is what controls the ignition spark.
hope that does it.
