Fuel pump problem...maybe?

[91 5.0 Greg]

My car died on me one night and hasnt run since.

At first, when the key was turned on the fuel pump would just continuously prime and the car would not fire. I replaced the relay underneath the seat and then the pump would not even prime at all. It wasnt until then that I learned about the inertia switch. With the new relay, the switch does nothing, no effect, but with the old relay the pump does not prime at all. By the way the old relay is missing one of the metal prongs inside of it.

Just replaced the fuel filter today, some really nasty black crap ran out of it so I was sure that was the problem, but she still wouldn't fire up. Car has now been sitting for a few months.

What could it be? What should I try next?

first see if you got power to the fuel pump. If you do and it still isn't priming then you need to get a new fuel pump. The more dirt and crap that goes through the fuel pump means the more it has to work which equals short fuel pump life
