ok my fuel pump wouldn't turn on when I turned the key in my 91 f150, so I replaced my pump, fuel filter and when I had it apart I made sure that the pump was getting power and that the inertia switch was popped. I put everything back together and put some fuel in and my pump still won't kick on and I don't have any idea what it could be. I have dual tanks, but I only use the side tank and there is no pump on the side rail. The pumps have FDM's inside the tank, but I don't know why it won't even kick on. I know the new pump can be bad from the start, but I'm ruling that out as of right now. I don't know what to do or where to start looking mitsurugi3...@hotmail.com wrote: > ok my fuel pump wouldn't turn on when I turned the key in my 91 f150, > so I replaced my pump, fuel filter and when I had it apart I made sure [quoted text clipped - 6 lines] > I'm ruling that out as of right now.

Care Address fake until the SPAM goes away ;-} Mitsurugi, electrical items aren't very mysterious, really. If you have electricity to the pump and a ground, and it's not running, then either 1. the pump is bad or 2. you're mistaken. Both are very real possibilities. You may be mistaken about the power as well. The point about the fuel selector switch is a good one. > Mitsurugi, electrical items aren't very mysterious, really.

I have seen circuits that with just a test light or even a multi-meter show voltage, but when a load hits the circuit, it fails.

Cut the clip lead in half, solder the bulb in, tape it up and your finished. Never assume the ground is good, test it. Always check the fuel pump before you put it in. Just because it's new does not mean it's good. Al > > "Joe" <Joe@dontspam.net> wrote in message > news:%g7Yg.1$yP2.0@newsfe04.lga...

You can do a voltage drop test across the ground, but its easier to just disconnect it, clean it and reconnect it Whitelightning |
