2000 Jeep Cherokee Fuel Pump

I drove home from work with no problems with my Jeep. This morning I went to leave for work and my Jeep wouldn't start. The starter sounded fine, it "acted" like it wasn't getting gas and I noticed that none of my gauges are working and my fuel light is coming on. I've put almost 4 gallons of gas in it and still nothing. I'm thinking it may be the fuel pump. Could you tell me where that is located? Do you have any suggestions on what this could be? I've checked the fuses and I have power. And the odometer is saying "NO BUS". I was told that means the computer is fine.

Thanks
