hey guys help me out here ive got a 97 blazer ls 4door and i have no power to the fuel pump/sendingunit and my fuel gauge lays wayyy over full when i turn the key on ive changed the sending unit and ive changed the ignition switch but still no power i tryed primeing with a 12v fused from batt to primer cable by firewall and still nothing so i switched the relay around with another one and still nothing please help:mad::mad::mad:

Are you saying your fuel pump doesn't run or that your fuel gauge is reading full all the time . A fuel gauge that always reads full is likely caused by an open circuit ( broken wire ) in the wiring between the gauge and the sending unit in the tank .

neither i have no power to the pump and the gauge is laying over full

i also have no spark at all
