First thing I would do is check the electrical connections to the pump. 
They're in a hostile environment and can make rather poor connection over 
time.

If you do find one pump is going bad, you should probably replace both pumps 
at the same time. 

The reasoning behind this opinion are that if you have one pump going bad, the 
other pump is working harder than it would normally work to maintain the fuel 
pressure. This causes more pump degredation whick in turn, cause
s it to fail fairly soon after one of the pumps gets replaced. (its only 
money!)

Sounds like it can be BS but this is what my expereince has been. The only 
other remedy would to be to use the troubleshooting guidelines in the bently.
