1994 caravan check gauges HELP!!!

I have a 94 caravan that recently the fuel pump went out. I replaced the pump and the van will run . But my gagues will not work no tach,oil pressure,fuel level,temp nothing, i have checked all of the fuses in the block under the hood and behind the dash. I also replaced the instrument cluster and cleaned all of my ground connections. Does anyone have any ideas????????
