The fuel filter is located on the left (drivers side) frame rail.It will either have two flare nut fittings,or a flare nut on one side and quick disconnect fitting on the other. With the engine off and key out of the ignition switch,remove the fuel cap to relieve any pressure in the fuel system.Use a couple of wrenches to remove the flare nuts or use your fingers to depress the little white tabs on the quick disconnect flange.You will lose a little fuel,so have a container such as a oil drain pan to catch the fuel.After the new filter is installed,put the key into the ignition and turn to the on position without starting the engine.You should hear the fuel pump pressurize the fuel system.Perform this step at least twice,then start the engine and check for leaks. Good luck.

SOURCE: fuel injectors
When you install new fuel injectors or are replacing the o rings, apply some lubricant to the o rings to allow for easy installation. I like to wet them with PB Blaster before I put them on the injectors. Also before you remove the injectors, blow out the area around each injector and the whole top of the engine with compressed air through a narrow wand (it gives you a very high velocity air blast that will remove all the impurities from the injector areas to keep them from getting into the engine when you pull out and install the o rings. I like to start at one side of the engine and work my way to the other and after that do a good overall blasting of the engine with compressed air to make sure all the sand and whatever else is out of where you are working. (Be sure to wear safety goggles when doing this procedure and at all times when working on a vehicle). When installing injectors, be sure to have all of them lined up with the holes and press evenly and firmly (you may have to wiggle the fuel rail a bit to get the injectors to go into the holes). Be sure to install all the fuel rail bolts and tighten them to specification. Turn the key on but do not start the engine to verify the injectors are not leaking. If you still have a leak, you may have a cracked injector body or a seal leaking on an injector.
Hope this helps

The last pieces in the chain are the fuel regulator and the injectors. The regulator is inside the throttle body, but it sounds that maybe the injectors are not firing. For nothing else, check out the connections to the injectors. Possibly they are clogged. Try a few treatments of injector cleaner.
