I checked my fuel pressure regulator and no oil squirted out could that mean my fuel filter is clogged. i already changed the fuel pump and that wasn't the problem

Test the fuel pressure, if it's low or non existant, you have a bad fuel pump, fuel pump regulator, or clogged fuel filter. That car has a throttle body, not a carburetor. All fuel injected cars have throttle bodies

if you could check fuel pressure is normal, if no pressure then no spray on injectors engine will not start, possible problems are clogged fuel filter, fuel pump not working properly, what i do to check is i squirt fuel on intake manifold and start the engine if it does start, only means one thing no fuel injected, so check fuel line, filter, pump, look for leaks. and fix

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

I would check the fuel pump relay under the hood in the black fuse box

The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.

1. Disconnect the battery ground cable.
2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
   
3. Remove the fuel tank assembly.
4. Clean the area around the fuel filter/regulator.

Fig. Fig. 5: Remove the fuel filter/pressure regulator retaining clip from the top of the assembly

Fig. Fig. 6: Replace the old fuel filter/pressure regulator mounting gasket

1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
3. Remove and discard the mounting gasket below the filter/regulator.
4. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.

To install:

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
3. Apply a small amount of clean engine oil to the O-rings.
4. Install a new gasket on top of the fuel pump module.
5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
9. Install the fuel tank assembly.
10. Connect the negative battery cable.

check fuel pressure, check fuel pressure regulator, change fuel filter. If fuel pressure is low it could be a bad pump, a clogged filter, or a malfunctioning fuel pressure regulator. If all those check out, then check crankshaft and camshaft position sensors.

First off you can simply check a fuel pump with a 9 volt battery by hooking up the negative end with one side of the battery and the positive with the other side. After making sure its working you check it with the vehicle. If theres no power this means either you have a short somewhere, or your fuel pump relay has gone out. I don't believe the pump would need to be primed, I would recommend making sure you are getting fuel to the filter or fuel injector rail/carburetor before trying to start it repeatedly.

CHANGE FUEL FILTER.YOU PROBABLY NOT GETTING ENOUGH FUEL TO START CAR.IF ALREADY DONE. YOU HAVE A INTAKE LEAK.OR MASS AIR FLOW SENSOR PROBLEMS.SCAN IT TO CHECK MASS AIR FLOW SENSOR.

Try taking a fuel pressure test on it, if you haven't already.
Could be a weak fuel pump, a fuel pressure regulator, or clogged fuel filter.

could be a clogged fuel filter. How long since you changed it?
It is located bolted to the frame on the drivers side. They only cost $7.00 so I would try this.
