Title: Noise on start up...
Post by: scarr89 on 24 August 2011, 10:41

When I turn the key to power on in my 150pd, not just when I start the engine up I always hear like a pressurised water moving noise. Wondering what it is? I can only assume it isn't bad as It has been like ever since I bought it...

assuming your car has aircon - does it still do it when you have it switched off @ startup?

IIRC that's the in tank fuel pump just giving an initial pump up to the engine. Mine makes a noticable "slosh" noise when first keyed on.

Yea, thats the one. Really sounds like someone flushing the loo! I kind of guessed it had something to do with fuel. I can now stop wondering..cheers  :smiley:
