Still no sparky
94 country AW4 4.0 All symtems led me to think CPS ie, fuel to rail cranking fine but no spark. Cap rotor looked good. Keep in mind this is a out in the boondocks bust, so no tester with me. Anyways I bought a new CPS and threw that in (fun when sitting insix inches of mud). Still no spark,,,yey

#1 cause of no spark is the crank sensor, which you replaced.
#2 cause is a failed ignition coil. Test and or replace it.
After that, it would be to verify the ASD system (search) and also the ignition switch itself is still in play.

Did you check your little 30 amp MINI fuse in the fuse box under the hood? If that's blown you have a ground out somewhere, probably the 02 sensor wiring, that was my problem 3 days ago, but now i have the same problem after i fixed the 02 wiring... not getting spark anymore and i replaced the coil, and cps already.
