If your sure no fuel is reaching the engine then first check the fuel pump fuse and see if the fuel pump is even turning on. It unlikely that is completely clogged causing absolutely no fuel to enter but if it does clog it can ruin fuel pump. it is very easy to replace though as long as its not in the fuel tank, check under the drivers side door in the frame rail. its a cylinder shaped thing in the fuel line. to replace first unplug the fuel pump, start the engine and wait for it to die, this will relieve the pressure. next taking two appropriatly sized wrenchs unscrew the connections, it will still spill a fair amount of fuel to be prepared. pop it off screw on the new one, hook back up fuel pump and start engine, may take a couple trys to start. its very easy and quick to do.
good luck
