How do you replace an intank fuel pump on a 1985 Ford Crown Victoria?

Answer 1

First you would need to depressurize the fuel lines, if there was any fuel in the lines. Then you would need to remove, or siphon the gas out of the tank, then remove the hose running into the fuel tank where you put in your gas. Then you need to raise you vehicle. Next you need to use something like a transmission jack, to hold your tank in place. Then you need to unbolt the straps holding the tank up. lower the tank slowly down to get to the fuel lines and to disconnect the electrical lines from the fuel pump, then take it down enough to take out the fuel pump, make sure that the fuel pump that you back in is the exact one for your vehicle. A good thing to do is to replace the fuel filter. After you put it all back together if it doesn't start leave the key on if you can't hear the fuel pump running, open the trunk up, behind the cardboard cover on the left side there is a switch press it, it should turn on which wold allow you to start the car whe you go try again. If this does not work you need to go back and make sure that you connected the electrical lines back up, and the fuel lines back up. Also you might check the fuel pump relay or fuse. If it still does not work you might have gotten the wrong fuel pump or you may not have power running to the pump. If this is the case you might want to go to an automotive shop to get the fuel pump power lines checked under the hood, unless you can locate and test them yourself. They would be near a can shaped vaccum cylinder. That is all I could tell you, it is what I did to mine.
