First, remove fusible link and computer from your list. Computers do fail but odds are it is something else and not that. Fusible link is either good or it's not. Aside from those items, everything under the hood is suspect till it's been tested and verified (fuel pump as well).
Begin with a code scan (most larger parts stores do that free). Get a haynes or chilton manual to use as a test guide and a decent multi-meter to do further testing. Use results from scan (if any) as a guide, starting point for testing.
Also be aware that sometimes a component can test good unless it's tested when the problem is actually happening. (fuel pump and cps can both do that)

    Replaced cps,distributer(cap,rotor,cam position sensor)checked coil good still no spark,replaced coil wire and plugs is the computer next?ignition control module is in the pcm i think

    If the check engine light does NOT come on when cranking at the times when it won't start, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. It's likely going bad, causing the delayed start problem typical of early 90's jeeps. Repair or replacement services for your jeep ECU are available on ebay.

    check the tps to see if the ohms are right,it may just need adjusting.then check the cps just to rule it out.but it sounds like its your fuel pressure regulator.

    99 Jeep Cherokee Sport, 4.0L -won't start

    you need to have it connected to an OBD2 machine and watch if you are missing the cam sensor showing RPMs
    or if your missing crank sensors RPMs,
    it could be a wiring problem or computer if your seeing the RPMs from both sensors,and the last thing i would check is hooking up a fuel gauge to the reed valve and watch what fuel pressure you have while cranking,if the cam sensor is the culprit it will turn the fuel off after the cranking.

    My 7.3 idles ruff till u rev it up a lil then its fine

    Change CPS (cam position sensor). You can get them from NAPA for around 30 but you can get one from international for a T444E which is the 7.3. for about 20 and they last longer/work better. Recently Ford has been sending all the owners of these trucks recalls for the cam sensor. If that doesnt work, check Injection Control Pressure Sensor, Fuel Filter, Injection Pressure Regulator, HPOP, and scan the computer for shits and giggles with a snap on machine to make sure the oil pressure is where it should be.

    Car will start but dies after about 10 minutes. Will restart after about 5 minutes but dies again after running a minute. Replaced fuel pump, fuel filter, attempted to clear codes by disconnecting battery,...

    Check and see if you have spark when it won't start. If it don't check the ignition module, Coil Packs,Crank and Cam Sensors. See if that gets in the right direction and let me know if not get back we will see if there is some more things we can look at. Ok thanks Bear001
