Id make sure that the mechanics who pulled the heads off which is quite an involved process, didnt damage the camshaft sensor wiring and any other parts of the electrical harness.
I know that's quite an undertaking, but you'd then know for sure, its nothing a nipped or damaged electrical wire is causing.

Disconnect the battery for a bit to reset the computer.

One possibly significant issue I found while looking in the engine is the EGR valve and solenoid assembly is extremely loose. I can easily move it by hand. The tube that goes from the EGR valve to the intake manifold is also movable and is definitely not making a sealed connection to the intake manifold. Could this be my problem?
go to weedahoe's profile and download the service manual. I believe there is a specific procedure that needs to be followed when replacing the crank position sensor.

Check that out and let us know how you make out.

Finally got a chance to work on the truck again. I borrowed a compression tester from a local shop. Tried it on 4 separate cylinders, no compression in any one. Looks like I have a long and expensive weekend ahead of me. Hopefully, just a timing chain.

No compression in any cylinders would definitely indicate you've got a big problem on your hands.

Time to pull the heads and check the timing chain (which I'm assuming broke)... if it didn't break than I bet the mechanics that put it back on screwed something up that caused the chain to jump the gear and fall off...
