94 mtx sho no spark

[green94mtx]

I have a 94 MTX with no spark.. All fuses are good. Tach works when cranking, so crank sensor should be fine. Cam sensor has power. Has good fuel delivery. And a new DIS Ignition module didnt do anything. Everything is good but still NO SPARK... Might be the Coil Pack after all. And if it's not the coil pack, then what? Any ideas?

A working tach indicates that your cam sensor is functioning properly. It has nothing to do with the crank sensor.

Try pulling the codes. http://www.shophoenixproject.com/eec/eec.htm

classic symptoms of bad crank sensor.


pull the codes as suggested rather than guessing.

Turned out to be the Crank Sensor AND a bad ground to the Ignition Module..
