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.

Try the Fuel tank
Inside the fuel tank.
4 hot ground ignitor from comp/dist to pump
Should be just one.
It is probably mounted in a box over by the air cleaner.
In the glove box, there are two buttons. one for the trunk and one for the fuel door.
it will be in the fuel tank.
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.
If no spark has been confirmed, then check the Ign. module, coil, & dist.
