       I think I want E) All of the above and more.  I always heard that when 
writing a test that included none of the above, you should include all of the 
above.
       You forgot to tell us what year and model Alfa you have.  Spica is a 
clue.
       If the Spica pump were leaking big time, the system pressure could go 
away.  That is not likely.  The fuel would have to be going somewhere, like 
onto the ground or into the oil pan.
       If the fuel pump is not working, you will have no fuel pressure.  If 
the fuel filter were plugged, you have no fuel pressure.
        Does the car have any gasoline to pump?  You could have a bad fuel 
pressure switch.  

       When you say, "gradually it lost all power." I assume you mean the 
Alfa, not the fuel pressure light.  If the car has gas in the tank, I would 
start with the fuel pump.  Roll under the car and put your hand on the fuel 
pump as someone else tries to start the car.  If the pump is not vibrating, 
it is not working.  Check the power to the pump.
       Next pull the fuel filter.  Does gas run out of the tank and down your 
arm to the armpit (I hate that part)?  Does gas also run out the other end of 
the fuel filter?  While you are there, just as well replace the fuel filter 
anyway.  No sense filling your armpit with gas twice.
       Just keep checking until you figure out what is not doing what it is 
supposed to do.
