Need to get to the basics.... Fuel, Fire and Air.... Ususally, air is not a problem unless your MAF sensor is offline and the ECM can't make a decision. Check the sensor and all ignition wires first.
Fuel is next. Turn the key to the "on" position and the fuel pump relay and fuel pump should energize. I would troubleshoot the relay first. It's the cheapest part to replace too. I believe the relay is located in the black plastic box in the engine compartment. Unless you have an electrical diagram and are handy with a multi-meter, just buy a new fuel pump relay.
The fuel pump is next. Check your fuel rail for pressure. There should be a schraeder valve (looks like a bicycle tire valve) on the fuel rail. Put on some safety glasses and use a small screw driver and depress the pin to release some pressure. You should get evidence of pressure and fuel. If you do not, then your fuel pump is suspect. Check the wires and voltage to the pump. If you're getting voltage and you have no pressure, then it's probably toast and needs to be replaced.
