The valve cover doesn't have that good of a ground for the reasons you site... also its not bare metal either.
Ok so this just got a little worse.
I was laying length wise under the jeep doing a resistance check on the CKPS. If I am understanding my multimeter correctly I am getting a reading of 000 in the resistance dept. which would indicate infinate resistance right? Versus it spitting out a number like 654 (which is what popped up when I tested it with each probe in a hand)
Ok so the worse part..So I am laying there about to pull myself out from under her and I happen to look up inbetween the tranny and the back of the motor and right there hanging from the upper back portion of the block near the rear main is a decent size drop of green fluid. Now where the hell did that come from? so much for progress sonofa.........
No change would be infinite resistance which is bad. If you were reading just the CPKS and the wiring harness was detached (in other words testing just the CPKS and not the computer and wiring harness too), then it is defective.
It's a 2000, so the CPS should not read a low resistance. Older Renix era CPS sensor should be 125-275 ohms. If he's got any spark or fuel injectors firing at all, the CPS is probably good.

CPS Testing
Crankshaft Position Sensor Connector (CPS/CKP)
TESTING PROCEDURE 1991 – 2001 4.0L H.O. engines
1. Near the rear of intake manifold, disconnect sensor pigtail harness connector from main wiring harness.
2. Place an ohmmeter across terminals B and C (See Image). Ohmmeter should be set to 1K-to-1OK scale for this test.
3. The meter reading should be open (infinite resistance). Replace sensor if a low resistance is indicated.
How does it work with infinite resistance anyway?
1. As Oldman had suggested earlier "index the cam" Wer got that done today with a timing light and a toothpick.
