Bad Fuel Pump?

Bad Fuel Pump?
My 98 z28 won't start. When I turn the key, the fuel pump does not engage (no sound). I checked the fuse for the fuel pump; it's good. I'm not 100% sure where the fuel pump relay is located because the cover is missing on the fuse box under the hood. I bought a fuel pump relay and swapped each relay out in the fuse box located next to the radiator, and tried starting the car each time. No luck.
So I have two questions: Where exactly is the fuel pump relay located? I tried finding a diagram online but couldn't find one.
Is there anything else I should check before I replace the fuel pump? I just want to make sure the fuel pump is bad before I spend hundreds of dollars and hours of my time replacing it. Thank you.

Are you sure? Because I heard in 98 they were moved to under the hood. But I may have heard wrong... I guess I'll rip up the carpet tomorrow.

fuel pump is 126 bucks at summit. check for juice at the wiring harness back by the pump with the key on. if u are getting power there and the pump is not coming on then u need to change the pump.

Problem solved. It wasn't a bad fuel pump. I accidentally found a "shock sensor" in the trunk near the spare tire. I basically just touched it and the fuel pump turned on. I guess the shock sensor is there to shut the fuel pump off in case of an accident. It was just hanging there so it must have gotten knocked around while I was driving. I taped it to the body of the car so hopefully it won't do that again. Thanks for all of your input though.
