i have a 1995 chevy 1500 p.k. and my fuel pump will not go off unless i disconnect the battery. i replaced the relay also unplug the computer and ingtionion switch to make sure they where not the problem. even with this all un hook if i connect the battery the fuel pump is up and running. i also figure out that if i take the relay out of the fuse panel and use a jump wire i can make it turn on or off. as soon as i start the vehicle it goes back to running all the time until i unhook the battery or jump across the fuse box
