Guest mrhobbz Posted March 17, 2008 Report Share Posted March 17, 2008 Picked up a new daily, 99' camaro Y87 package, at an idle it has a strange whistling noise almost sounds like a vacuum leak but its coming from about the middle/rear of the car. Got out and listened for an exhaust leak but didn't hear much. I can only hear the noise while the doors are shut and the windows are up. Ideas?

AJ Posted March 17, 2008 Report Share Posted March 17, 2008 stock exhaust? since its a V6 it may be sometimg in the exhaust that when the exhaust gas flows over it at idle it makes the noise. the corvettes had something along the lines but it sounded like a jingle and it was due to a hole that was drilled in the H-pipe on the inside.

Guest mrhobbz Posted March 17, 2008 Report Share Posted March 17, 2008 Had the dealership look at it, fuel pump is going out. I know its inside the tank, can you get to it from the hatch or no? Quote Link to comment Share on other sites More sharing options...
2 Sweet Posted March 17, 2008 Report Share Posted March 17, 2008 Are you sure it's going bad? Many fuel pumps, mainly aftermarket units, are just plain loud but they still work fine. A lot of people cut an access hole in the floor of the hatch area. Otherwise you gotta drop the rear axle and all that fun stuff in order to change it.

Yeah it very well could be an aftermarket fuel pump, that was just the dealerships guess. Ran fine didn't seem to have any fuel delivery problems, it also has an aftermarket exhaust so it very well could be a fuel pump. Quote Link to comment Share on other sites More sharing options...
2 Sweet Posted March 17, 2008 Report Share Posted March 17, 2008 I wouldn't worry about it then. A previous owner probably just replaced the original pump with a cheap one from NAPA or something. When the fuel pump starts to crap out, you'll know something is wrong Quote Link to comment Share on other sites More sharing options...

When the fuel pump starts to crap out, you'll know something is wrong Yeah i didnt figure it was anything to worry about, the car runs quite strong and didnt have any fuel issues so i'll just worry about it if something comes up. Thanks for the info. Quote Link to comment Share on other sites More sharing options...
Guest mrhobbz Posted March 17, 2008 Report Share Posted March 17, 2008 I got the dealership to agree to fill the tank up before i drove it off the lot, they did and they say the noise is now gone. Guess we'll see when i get there. Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted March 17, 2008 Report Share Posted March 17, 2008 I have an OEM fuel pump if you need one, and can help you with the "trap door" mod if you wanna go that route. Takes an hour to replace the pump the first time, then 30 minutes thereafter. Quote Link to comment Share on other sites More sharing options...

Takes an hour to replace the pump the first time, then 30 minutes thereafter. I did the ''trap door'' mod yesterday installing a Racetronix kit on my brother 95 Z28. WAY freaking easier then dropping the axles, tank, ect. installed everything in about 3 hours. Better then the 7-8 hour job Alldata said it would take to install a new pump!
