ya I know, I do alot of troubleshooting in my carreer and it is easy to get off track, especilaly when its something you are not real knowledgable with.

I pulled the PCM out and checked it over, when I put it back in it ran great for most of the day, then all of a sudden it started screwing up again, Now for the last 4 days it will not start at all.

I am thinking pretty heavily that it is the crank position switch, I should look and see if I have any spark before I get to carried away, although if the Crank position switch is not working the pcm will probably not allow the car to start, so it could be either one I suppose.

Ya I think I should still try changing the Crank switch first.

Oh by the way as I am looking at the damper at the 3:00 position is the crank switch
but I also see at the 11:00 position there is another sensor or something, anyone know what it is, I found that the connector was almost completely broke off and may have been intermittently braking contact. I put it on all the way now but the car still doesnt start, I may have also burnt it out with the bad connection issue..

The 3:00 o'clock position would be about right for the crank sensor. (the connector plug goes to the right -toward the radiator) The 11:00 o'clock position would be about right for your cam sensor.

Also, the cam sensor is quit small in physical size, and is attached with only one bolt.
The crank sensor is much larger, attaches with 2 (-or was it 3?) bolts. Also, I think you'll find the crank sensor has a fairly large plastic cover snapped over it.

Be sure to reply back on this message after you find the problem
