Won't start, fuel pump? Options

[#1RAGE]

Just since this last weekend, my 914 has been having trouble starting. It turns over and over but doesn't start. Two out of three times trying, I got it to start. The last time I noticed just before it finally started, I heard a buzzing sound come on. Normally I hear this buzzing sound coming from the front of the car when it is running. Is that noise coming from the fuel pump?

I have heard that some people relocate the fuel pump to the front trunk area. If that is the case with my car, would the fuel pump likely be underneath the tank?

Just to make it clear. Normally I hear a buzzing noise coming from the front trunk / gas tank area. Recently I have been having trouble starting the car but just before it does the noise appears... which leads me to think it might be the fuel pump.

I'm not much of a mechanic. I remember looking for the fuel pump a couple years ago and couldn't find it in the engine bay; this also leads me to believe it is up front somewhere.

Thanks in advance.

Alright, made some more progress today.

Got a good buddy of mine to help me. We pulled the gas tank out and the fuel pump was underneath it.

We're not experts on the electrical stuff so hopefully someone here can help.

We disconnected the fuel pump and hook it up directly to a battery and it seemed to work fine. When we pumped a bit of clean gas with the pump out of the car, the gas coming out was very dark and dirty looking... that can't be good, can it?

Then we tested the voltage of the wires going to the fuel pump, at the fuel pump end. We got a reading of 0.25 V no matter what position the key was in. When we unhooked the white connector on that relay (picture in my earlier post), we got 12 V but again no difference with the key on or off.

What does that indicate? Shouldn't I be getting 12 V only when the key is turned on? Is there any way to test the relay?

Thanks!
