Pull up the back seat and listen when you turn the key to on: no buzz electric pump is shot. When you are replacing it you must check the siphon jet before it leaves you stranded check my diy siphon jet repair thread

It's so easy to swap a pump and with lifetime warranty I wouldn't shy from the instant gratification of the Delphi unit. I'm driving with a pump that is near end of life I may buy a "pump only" solution to keep in the trunk for the inevitable failure.
