This worked for awhile, but now it wont start at all...the fuel pump works fine whenever I get the jeep to start...
If the check engine light does not light up on the dash when you turn on the ignition, at those times when your jeep doesn't want to start, then your main jeep ecm is in need of repair. The fuel pump relay will get energized only after that check engine light comes on. It's a known problem, especially with the first and second year production Grand Cherokees, 93 and 94.

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.
Good luck

Probably the upstream o2 sensor (could be downstream).
or the other possibility it
could be a vacuum leak.
just check out .that will solve your problem.

A 50/50 mix of an ethylene glycol based anti-freeze and water is recommended at all times.
The solution not only has a lower freezing point than water, it has a higher boiling point to prevent overheating.
Year round it acts as a rust preventative.
If you have A/C, it will prevent your heater core from freezing up.
Alcohol or methanol base coolants are specifically not recommended.
But to answer your question specifically:
To start, just water will work.
If this helped, please take a second and rate my response.

My daughters jeep had the same problem. We fixed by finding the wires that run beside the manifold down under the car. The conduit that have the wires in it was worn away because of resting up against the manifold, causing the wires to short the system out. Once I replaced the conduit and taped the wires it has not shorted out again. By the way, the Jeep dealer couldn't find the problem.

The crankshaft position sensor was seriously problematic in those old jeeps. It's located towards the top of the bell housing slightly to the driver's side I think.
Disconnect the negative battery cable and then remove the fuel tank cap to release fuel tank pressure. Remove the fuel pump relay from the PDC. Start the engine and allow it to run until it stops. Select any injector and unplug its connector.
Connect a jumper wire from an injector terminal to the positive battery terminal. Then, connect the other jumper wire to the other battery terminal. Briefly touch the end to the negative battery terminal.
Locate the fuel filter/pressure regulator near the front of the fuel tank, mounted to the body above the rear axle. Disconnect the fuel supply, fuel return and fuel pressure lines. Remove the mounting bolts and then the fuel filter/pressure regulator.
Attach the new fuel filter/pressure regulator to the body and tighten the bolts to 30 in-lbs. Reconnect the fuel supply, fuel return and fuel pressure lines. Reconnect the negative battery cable. Start the engine of your Jeep and check for leaks
