Fuel pump relay, where is it?

Ok, i posted about sugar in the tank with my friends car and we doubt thats what it is ....

Now, i can't hear the fuel pump whine when you turn the key, (I also live in a busy neighboorhood so its hard to hear). But anyways, I have not a clue where the relay is and what it looks like.

Did the McGyver spark plug test by holding it onto the manifold and it sparked. Then I tested the Schrader valve and no fuel came out when the pump should've had pressure.

Can anyone tell me where the relay is and what it looks like?? Pics would help alot. I tried a search here and the articles I read don't say where it is. Plus the haynes manual is useless. I know hardly anything when trouble shooting a MPFI engine.

Thanx everyone

It's one of the two relays on the firewall right next to the brake booster.

ok, thanks tested it and still no go ..... it was the fuel pump. Tried dropping the tank but it was too much work for us. Since we have a machine shop for a garage and all the metal we need, it was easier to cut it out like this.....
