16v fuel pumping woes

[sciroccos at earthlink.net (Jim Ruffi)]

Time to get out the ole' test light or meter...you should simply get 12V to
the pump terminals when you're cranking.  You can easily get to the
terminals, which have a wire connected to each, with a little rubber boot,
which pulls away.  If not, a pump is about $160 and an hour or so to change.

If somehow you're mistaken and the tank pump is also not running, you should
install a fused jumper in place of the relay (per the bentley) to test the
relay/wiring.

Tip: disconnect the fuel lines from the tank before you change the pump.  I
think less fuel comes out this way (no siphoning)..not 100% sure that is the
case, but I do it anyway.
