Question about 1996 Jeep Grand Cherokee
Motor turns over good, battery good, fuses and breakers good.
I have no fuel pressure and no spark. No volt gauge and no gas gauge. I have swapped the pcm to my 97 grand cherokee and the pcm started my 97 just fine. swapped out ignition switch and that didnt work.
No volt gauge
No fuel gauge

Ok, I had a very similar trouble. It cost me a lot in diagnostic time, but here's what my mech. found.
Symptom, no fuel flow. I don't remember the guages status. Fuses and relays were good. but had blown fuel pump fuse in the past.
Found: Hose connector (A.C.) in vicinity of the fuse box under the hood. (underneath) was chafing the harness from the fuse block to fuel pump, guages, etc. wiggle adjustment temp fixed. Mech found short/ground/ exposed copper wire and repaired the connections. also, protected wire from future damage.
A poorly place connector / harness and vibration were the contributors to the incident. Fix was good and so far permanent.

Let me guess- your check engine light doesn't light either, does it? Unplug the crank sensor and turn the key on. If the check engine light comes on, replace the crank sensor and drive away happy. That's what I did. You can also verify the crank sensor by using an ohm meter- if you get a resistance reading, the crank sensor is bad. Good luck. I believe it's the black and red wire you need to pull the reading from- but honestly not positive.
