check your Fuel pump relay. 93 models have the FP relay in front of the passenger side strut tower in the engine bay, near the MAF sencor....you'll see 2 relays, the other one is the A/C compressor control relay. fuel pump Part number is LRS-14089A. hope this helps.
Might be the inertia switch. Open the hatch, and on the left side along the back panel is a black rubber grommet. Remove that, and peer inside to push the red button on top of the inertia switch. Sometimes they get tripped or the wiring is compromised.
