look in the gas tank ;-) Specifically, I don't know. Generally, it will be under the dash, often combined with a fuse block that has relays on it; in the engine compartment also in a relay block that may be under a plastic cover; sometimes it is plugged into a pigtail on an electrical harness by itself under the dash or in the engine compartment. You will need the exact service manual for this location or someone who is familiar with your exact vehicle model. As you can see there is no set location by manufacturer or carline or model. My 93' Topaz had it attached behind the steering column with a plastic bolt of some sort. It required taking off the plastic panel below the steering wheel, then the metal one behind that. The metal one had 4 bolts, two plainly visible on the bottom, and two under cover plates on either side of the steering wheel. From there, the relay was quite a ways up and behind the wheel, and required breaking the afore-mentioned plastic bolt to get it loose.

Inside the fuel tank.
Should be just one.
Check all the fuses, if all are good, check the shut off relay.
The fuel relay switch is located in the trunk on the left side. There is a hole and a red button behind it.
it will be in the fuel tank.
behide the glove compartment towards the right its a silver relay that's bolted to the dash frame color of the relay may fary though

the fuel pump relay is located in the constant control relay module ( a black box about 6x4x1 inches in diameter) and should be located on the left shock tower near the battery. it has a double connector and about 17 to 18 wires. there are also other relays in the module, i am not sure whether the relays are replcaeable or if you will have to by the whole module.
Well, If you mean the fuel pump in the fuel tank, it is a 12 volt pump. The pump runs with the 12 volt system of the car.
I believe that it is in the trunk left side behind the cardboard panel. Should be a sticker there indicating this.
