It's not really that bad... it just seems that way.

I remember many years ago reading that the single highest amateur 
"misdiagnosis" of a car not working properly was the fuel pump.  Heck, 
I've done it myself.

For instance, look at the current two or three threads on the 
occasionally dying '85 cgt - they say "fuel pump" and "fuel pump relay" 
over and over again, and yet the odds are the problem is nothing of the 
sort.

Add in the fact that we have these hard-working fuel pump relays (they 
often supply power to things like the OXS heater, too) that *turn off* 
if there is no spark, and more blame than is justified gets heaped on 
that system.
