Is your Tach moving when cranking?

I bet you are right when you say it isn't the CKP.

The sensor is located about 4 inches behind the a/c comprssor. First - disconnect the batteries! A bracket will then need to be removed: The two lines to the tranny filter go under the bracket (wiring bundle bracket that also secures the ground wires to the block above the oil pan and above the steering stabilizer) that needs to be unbolted to gain access. It is held in with an 8mm bolt - a long (16 inch) extension with a pivoting adapter is what is needed. Long needle nose pliers with a 45 degree bend would have helped also. Like stated before, unplug sensor before removing and plug it in after installing. (The wire is not long enough to make it easier after removing sensor.) Long skinny arms and a lift will help alot.

Some folks remove the A/C compressor to access it more easily, but it really is a lot more work that way AND one bolt is at a horrible angle, so if you do .......... BE CAREFUL not to strip it.
