Think a fuel system issue....

[crispy520]

So I haven't driven my old Integra GS (92) in some time (it's been several years) and now I have a desire to get it back up and running. I'm pretty sure what I have is a fuel system issue, or more specifically a lack of power to the fuel system. Here is my rational:

The fuel gauge always reads empty even though I added 5 gallons.
Do not hear fuel start (prime) with key in. No hum from rear of car.
Added new main relay (7 blade in dash). Could only find a single one in town.
All fuses check out (under hood and kick panel).

So before I move on to spark and such I want eliminate the pump altogether. What would be the next step? I'm in a time crunch so I want to avoid unnecessary steps/work so looking for a guiding hand.

Should I check power connections under seat?
Should I move to dropping the tank? Is there a best method to do so?

I'm mainly concerned with the fuel issues but any advice would be good...

So since this post I have done a few more small steps related to power to the fuel system. I tested the main relay connections and the connections per this guide:

Power seems to be where it should and when it should. I did not check voltage to pump though so low voltage may be possible as well. Also thinking of jumping power to the pump directly to prove/disprove cabling issues. So if the pump works with direct power it is cabling and if not I think I have a pump issue. So based on the electrical schematics I think have eliminated all fuses/relays between the battery and fuel pump.

I have already drained the tank via bolt on bottom. Gas looked bad but I hope the fresh I added acted to flush the tank. So is there an easier method or technique to help in dropping the tank?
