Hi,

I agree with you. If you have no spark and the tach isn't moving, the first suspect is the crankshaft position sensor.

Here is a link that explains in general how to replace one:

If you look below, I attached the directions specific to your vehicle. On this engine, you will need to remove the starter motor to access the sensor.

Let me know if this helps or if you have other questions.

Take care,

joe
