96 LT4 fuel pump problems
My 96 has been running great with no issues forever and three days, but not realizing how low the fuel in the tank really was, I ran out of gas on Monday. After putting some gas in the tank (4 gallons), the engine will crank for days, but will not start. I can get it to start for a second using a shot of starter fluid in the throttle body, which is making me think it is either the fuel pump or the relay.
After killing the battery cranking the engine over, I also replaced the battery. When putting the key in the start position, I cannot hear the fuel pump prime like I used to. I have experienced a faint gas odor since owning the car, but assumed it was a very minor leak at the fuel rail or injector.
So, here are my questions:
Thanks much for the help!

So, here are my questions:
- Do you know where the relay can be found?
- What is the procedure to replace the in-tank fuel pump (I have the FSM at home, and can look that up later if need be)?
- What is the recommended performance fuel pump (My near-future plans include installing exhaust, headers, intake, and high flo injectors)?
- With your experience, how likely is it to be the relay, given that it was working until running out of gas?
Thanks much for the help!

Raceteonix has a great fuel pump replacement kit.
2 choices for pump volume, I'm using the smaller pump and it should be good for the 400ish hp my 383 will put out when I get it built.
