Did you check all your fuses? That should be your first step.

Is the check engine light on?

On the 2g, crank signal fires the coil pack for spark, cam signal fires the injectors and gives power to the pump.

There is a bunch of different things it could be. Power transistor (black skinny square box by the coil pack), Cam sensor, Crank sensor, MFI relay (under the dash on the passenger side of the center console).

Easiest way to figure whats going on is with a scan tool to make sure the cam and crank sensor are giving the ECU a signal. Also could have a buddy try to start the car while you test for power at the fuel pump.
