I can help....
I just spend days troubleshooting a no Fuel Pressure problem. Here is how it works and it sounds like your answer is fairly straight forward. I have a 92 EECIV in case yours is different but I doubt it.
You turn key to start, which tells EEC to ground the fuel pump circuit, on mine this is pin 22, which happens to be the same lead that goes to the test connector, if you have any service manual (Haynes or Factory) it will show you this connector. When you ground the far left terminal on this connector, labeled in diagrams fp, and key is on, fuel pump should run and pressure go up as normal. This proves fuel pump works, etc. Now without the this terminal jumped to ground. The EEC grounds the fuel pump via internal connection to complete the circuit, but it must get enough voltage about 12volts from the red wire circuit 361, supplied by the IRCM, two common open grounds are the IRCM itself (black wire, I think it is pin 3 on connector) and there is a round connector right next to battery which gets corroded from battery inside, if either of these have bad ground, no fuel pump action...good luck.
