replace the fuel injectors, that is the likely cause......
to test the injector, take the power clip off the top of the injector, take one wire and ground it to the body of the car, and another form the battery, to the other post on the injector, if you do not hear a pulsing sound coming from the injector it is bad, if you do, then you have a wiring problem.

Find the pressure test port (looks like a tire valve) on the fuel distribution rail over the injectors and place a can over the open end of the valve. Press the inner pin to release fuel into the can. If the pressure seems to fall rapidly, replace the fuel filter. Is the check engine light on? Rent a scanner, read any code(s), and pursue to repair(s). A bad crankshaft sensor or camshaft sensor can prevent the injectors from firing fuel into the engine.

the fuel filter is located down under the middle of the frame rail, on the drivers side,remove the lines from the filter, look out b/c some fuel will come out after diconecting the line. replace with the new filter make sure you get the "FLOW" "should be marked on the filter" pointing to the front of the car
