No, I have not tested the voltage at the pump as I'm not equipped to test
voltage anywhere. Just don't have the tools and knowledge to do it.
Also, coincidentally, my other car (a 2002 Miata) is having trouble as well
and I need to get that straightened out.B
But thanks for the information. I guess I'll have to get the Alfa towed to my
mechanic. I just hope the fix isn't expensive.

b Colin,
Your fuel pump is working only because the engine started.B Normally the Low
Fuel pressure light is on until the fuel pump brings the fuel pressure to
working pressure.B 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.B 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.B 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.B 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).B The engine compartment
filter will catch the small stuff.B 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.B BTW, did you test the voltage
at the pump ??

B B Just to bring this up to date:
The car has started since the initial failure. What I get now is the low fuel
pressure indicator light (or at least I get the upper left hand red light)
continuously on (which I've never seen before) and there is NO fuel pump
sound
at all.B
I was, however, able to pull it out of the driveway and get it into the
garage. I don't want to drive it any distance like that, of course, but it
does in fact go.
Is this consistent with a failed fuel pump? Or something else? Does the
supplementary pump in the gas tank provide just enough fuel to allow it to
go?
