> #1: What would be the symptoms of a faulty fuel accumulator?

unless the problem with it is that its leaking, you wouldnt really notice. i'd
say about 25% of the fuel accumulaters i've come across have been frozen (as in
not doing anything useful).

> #2: What would the symptoms of a faulty fuel pressure regulator?

improper fuel mixture. problem adjusting DPR current. unstable idle. loss of
power. cis requires fuel pressure to be very closely regulated for it to work
properly. note: if the vacuum line is not connected to the FPR, it can appear
that it is bad.

fuel punp relay / associated electrical problem. if its a new pump, i would go
after what was touched during the install (i.e. electrical connections to pump).
also, hook up meter to fuel pump wires the next time it wont run. if the meter
stays at 0, its not the pump. if it goes to ~12v, but the pump doesnt run,
return that thing.
