bColin, Your fuel pump is working only because the engine started. Normally the Low Fuel pressure light is on until the fuel pump brings the fuel pressure to working pressure. Most of the time you never notice it is on at all.
SPICA systems do not have an auxiliary pump in the tank; the Bosch FI started the in-tank aux. pump design. I'll suspect that if you turn the key to ON, the pump is working but it just isn't as noisy as before since it isn't passing the usual volume of gasoline. Much of the noise is the gasoline traveling thru all the tubing. My '73 GTV has two fuel filters; 1) right by the gas tank by the pump, 2) under the hood on the passengers fender. The tank filter gets the big stuff such as flakes of rust from the tank - my tank would clog a new filter in 3 days until I got it Renu'd (http://gastankrenu.com). The engine compartment filter will catch the small stuff. IAP sells the engine compartment filter ( http://www.international-auto.com/index.cfm?fa=p&pid=2491&posid=855603). It still could be that your pump is marginal. BTW, did you test the voltage at the pump ??
