At the relay check for voltage on the pink/blk wire,then with engine cranking check for voltage at the gray wire,the gray wire goes to the fuel pump,the pink/blk wire comes from the fuel pump fuse and is ign on voltage,there should be a fuel pump test connector that breaks out of the harness near the relay,has an open green or red colored connector,jumper that the voltage and the pump should run.
