Suba9792 Posted March 28, 2010 Share Posted March 28, 2010 So, I'm fairly sure about this, my 92 loyale has a humming from the back, to me it sounds like the fuel pump, I have had built chevs in the past that have loud fuel pumps and it sounds alot like them! is this normal? it's not hesitating at all or any obvious fuel loss, should I replace it? Wanted: Pug 14" 4x140mm steelies or alloys with nuts. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 28, 2010 Share Posted March 28, 2010 The SPFI pumps tend to make a whirring noise when running. It's pretty much normal. Most of them do that. They can fail but it's rare. Mostly they either last till the end of the car or in some parts of the country folks have problems with the surge pot on the end rusting out if exposed to too much salt. They are also VERY expensive for a direct-fit replacement. If you have to replace it there are a number of posts about some Ford F-150 pumps that will work as an alternative.

bheinen74 Posted March 28, 2010 Share Posted March 28, 2010 the fuel pump "buzzing" is more than a hum even on my 85 BRAT. oh well, it is telling me the car is on. lol since mine is quiet exhaust. the sound is comparible to a microwave oven when on high cooking something.

GeneralDisorder Posted March 29, 2010 Share Posted March 29, 2010 the fuel pump "buzzing" is more than a hum even on my 85 BRAT. That is a completely different pump, but they are also noisy. It's a solenoid style pump so they are naturally going to make a rapid clicking noise. Sounds a bit like a helicopter. GD Link to comment Share on other sites More sharing options...
kerandt Posted March 29, 2010 Share Posted March 29, 2010 Have a '91 Loyale and also a '93. Both have fuel pumps that are quite audible. The '93 had a bad pump when I got it. Sometimes It would start and other times it wouldn't. I ended up just getting another used one off of Craigslist. Seems someone is always parting out a Soob. They're easy to get and easy to change. Might just see how long it lasts and carry a spare? Link to comment Share on other sites More sharing options...
PlaneDriver Posted June 26, 2010 Share Posted June 26, 2010 The fuel pump on my '89 RX sounds like a mosquito (buzzing) after the car has been running for than 15 minutes, especially when it's hot out. It has done this off and on for a while so I'm not extremely worried, but if this is a sign of impending failure, I would like to take care of it.
