1990 Jeep Cherokee 6 cyl Four Wheel Drive Automatic

Hi. I own a 1990 jeep cherokee laredo. Just recently it has not been wanting to start. It will turn over but it won't start. I've already replaced the crankshaft position sensor, distributor cap, rotor, spark plugs, and wires. I have no idea what could be wrong. Can you tell me what I could look at or replace to fix my problem? I would really appreciate any help at all.

Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!
