Easy bro, your first post was at night, then you're expecting a response the next morning? Your post is hard to read, try using punctuation.

You need to get a multimeter and see if the ECU is sending the fuel pump any power. Have a friend try and start the Jeep, if it reads 12 volts then you either have (1) a ground problem at the pump or (2) your pump is bad. If the multimeter isn't detecting any voltage and you have replaced the relay, you could have a bad ECU. Can you hear the relay tick if you turn the ignition to accessory?

I had the same problem on my 95 2.5L. I found out that the ECU had gone bad. I bought a ECU and wiring harness from a guy on Pirate for $100.00 shipped. I had already removed the tank, so I figured I'd see if the fuel pump was working. I took my battery and connected it directly to the pump and it fired right up.

On the drivers side. Behind the rear wheel, inside the frame rail, you should see wires leading up to the top of the tank (fuel pump/sending unit). There is a connection block that you should be able to access, by pulling the wires back a bit. You should be able to disconnect the connecters and use a meter to test for power to that point. If you have good power to that point, then you need a replacement fuel pump/sending unit.
