myUsername Posted November 4, 2005 Share Posted November 4, 2005 When I put my key in the on position (when the needles do their sweeps), I hear this whooooop noise coming from the engine bay. This only happens when the engine is cold. Anybody else hear this with their car? In my previous car, I heard something similar and it turned out to be the starter going bad. Thoughts and opinions please. Link to comment Share on other sites More sharing options...
melayout Posted November 4, 2005 Share Posted November 4, 2005 From http://www.legacygt.com/forums/showthread.php? t=20588&highlight=fuel+pressure+regulator : From http://techinfo.subaru.com : Quote: Noise from Pressure Regulator Service Bulletin #09-41-05 Pages: 2 Bulletin Description: The purpose of this bulletin is to address noise that can occur when turning the ignition switch from the ýONý position, to the ýSTARTý position during engine cranking. When the ignition switch is turned on, the fuel pump begins to activate and pulsate. This noise may be audible. The pressure regulator was modified to prevent this pulsating noise. If you encounter a noisy pressure regulator, replace it with the modified one. Actual TSB at http://www.scoobymods.com/forums/showthread.php?t=4809 . I've had it since day one and 35k miles later I haven't bothered bringing it up to the dealer since I don't want to mess with anything if it ain't broke.

chinchy Posted November 9, 2005 Share Posted November 9, 2005 I don't know... I have this exact same problem, and I showed them the TSB for the Fuel Pressure Regulator, and they supposedly changed it out. But I'm still having the sound sporadically...

Gire Posted November 9, 2005 Share Posted November 9, 2005 I have just started to get it too... now that winter is here. It is kind of a whoop whoop whistling noise upon cold engine start up... I'm glad I stumbled across this thread. Thanks for the info Melayout. Not too concerning that I will make the dealer fix it though. Link to comment Share on other sites More sharing options...
iguanamafia Posted November 9, 2005 Share Posted November 9, 2005 I get it from time to time and I dont think its coming from the engine bay. It almost sounds like its coming from under the dash. Link to comment Share on other sites More sharing options...
TSiWRX Posted November 9, 2005 Share Posted November 9, 2005 I'm with some of the other guys in that this noise doesn't particularly bother me, and I haven't encountered it but, like, perhaps twice, so I haven't felt the need to pursue this TSB with the dealership.... It reminds me of my old DSM's Walbro, the "Knight Rider mobile," so I'm not particularly concerned. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
myUsername Posted November 12, 2005 Author Share Posted November 12, 2005 Original poster, How about a follow up? what was it? did it get fixed? If you're talking to me, I didn't get it fixed. I followed the link and it seems like it's just another one of Subaru's quirks. If it happens more frequently and gets louder, then I'll give the dealership a try. It will probably be hard duplicate once the engine has warmed up...and if I leave it overnight and have them try to duplicate the problem, the tech will probably not hear it in their noisy shop.

Beanboy Posted November 16, 2005 Share Posted November 16, 2005 Get it from time-to-time... The less time at the dealer the better when it comes to cars from the I perspective, so I'm not planning on bringing it in for this. -B -B http://www.standardshift.com Link to comment Share on other sites More sharing options...
Rollin Wes Posted November 18, 2005 Share Posted November 18, 2005 Good to know this. My car does this often, but only when I go out and crank it up to go to lunch. I have been thinking it was the starter since the sound only happens right at ignition when the starter is turning over. Link to comment Share on other sites More sharing options...
