Question about 1993 Jeep Wrangler
Check the coil output. you should have a good healthy spark both from the coil and at the plug ends of the wires (should easily bridge a 1/4" or most times even wider gap.) I would also check the engine compression.
You did change the fuel filter when you did the pump? How does the air filter look?
if everything I mentioned checks out as good, then you will need to get a chiltons, haynes or other manual and individually test all sensors etc to see if anything is out of range. Obviously with numerous items that can potentially cause the same problem, no one can guess what exactly the problem is but I hope one of my suggestions points you in the right direction.
