Just make sure you have 12V at the connection going to the pump before you replace the pump. I connected a light to the plug just before the pump. Turn the key, if the light comes on for a few secs and then goes out, continue with your plans for pump replace. If no light, it could still be the solinoid, or another connection.

Got the replacement pump / motor from rock auto. Installed really easy.
How do you remove the fuel filter on the bottom? I got a new one from the dealer and would like replace my dirty one. |

boo... put the fuel pump in and still got no noise from the unit.
I guess it's a time for a trip to the dealer. This sucks. Im guessing it's something to do with the harness on the fuel pump as im still getting a pulse 12v reading on the harness |

Then your problem is between the connector and the pump, right? Check continuity on those wires. Be careful about energizing stuff around an open fuel tank though. I'd remove the pump again and use an ohm meter.

gonna do that when i get back from nyc. If it is the connector, can these be purchased separately? Or somehow replaced, I would hate to pay $500 for a fuel pump when all i need is the connector?
