I recently acquired a 97 jeep cherokee 4.0 4x4 with 66000 original miles. I bought it without it running but it cranked just fine just no spark. Since then I determined the crank sensor, fuel pump, PCM, and alternator were bad. The alternator was locked up, the PCM the previous owner swapped with a junkyard one. I now have proper fuel pressure, good spark, correct timing, and good compression. It cranks and cranks, but will not start.
