Major problem fuel pump not workin dont know why!!!!!!!!!!!1

i have a 1995 nissan pathfinder se-v6. i took it offroad and got it sunk in some wet coquina ( i think thats how you spell it) and ended up layin frame. well i ended up gettin my buddys dads old toyota truck to try to pull me out and while he was snatchin on me my truck sounded and acted like it ran out of gas while it was running. so i made an emergency trip to the gas station and put a quarter tank in it. well it wouldnt crank. so we ended up havin the owner of the property lift my truck out of the coquina with a trackhoe and got towed back to my bodys house were we then pulled the fuel pump. as soon as we got the fuel pump out i turned her over and no sound from the fuel pump. so i tore down the fuel pump housing and straight wired it to the battery using audio wire to check if it was still good and as soon as it made a connection the fuel pump kicked on and ran so i know the fuel pump is still good. so next i checked the fuel pump relay and the eccs relay and replaced them just in case and still nothing so i took them back. and put one of the old ones in the other one was damaged when it got ran over by my buddys blazer. so i still have to get one more so i ran the self diagnostic on the eccs and everything checked out fine so i cleared out the codes and checked it again still says its running fine so i cleared and checked 3 more times and every time it said every thing checked out. so i stuck an ohm meter on the wires from the relays and the ground was a lil off on one and another negative lead i dont know wat it is also registered up weird on the ohm meter. anything else i need to check or any suggestions as to what could be wrong? if it helps any the truck will turn over but there is no fuel goin to the motor since the fuel pump doesnt have any power going to it. any tips or suggestions will help greatly shes been down for almost a month and i really need to get her back on the road. thanks
