2 fuel pumps gone bad? 850 1997

posted by  someone claiming to be DaveDiddly on  Thu Apr 1 09:53 CST 2004 [RELATED]

855 T5 w/ 140k mi and ipd ECU

Two months ago, the car would not start. I noticed there was no fuel pump whir when key was in 2nd position. Checked for power at the fuel pump, 12V there, yet pump wasn't going.

Replaced pump with a used one ($125) instead of a new one ($440). Car worked fine for two months.

Then, it decided to stumble and die while driving. Would not start again, same symptoms as before. Occasionally it would run for a couple minutes though, then stumble and die again. Otherwise, would not start at all.

Checked power to pump, 12V, but nothing was pumping.

On a whim, I dug up the original pump I took out 2 mo ago, gave it 12V, and it happily pumped out bits of gas left inside and sprayed it on my carpet. :)

Any ideas what would cause two different pumps to not work right when given ample power?
