Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

How to listen or know if the injector/s are they pulsing? What's a noid light? Also I checked the fuel pump relay switch, good. Not sure where the fuel pump fuse is, also how can I check the timing belt? If I'm near the tank and have someone turn on the ignition I should be able to hear the pump, correct?
