Need help. 04 V70R no start "Reduced Engine Performance"

[Jhal42]

Ok guys at the end of my rope. Car won't start. Cranks but won't turn over. Battery is good. Reduced engine performance message. Cel flashes then turns off. Some kind of electric motor whine under air box. Read on here it might be the fuel pressure sensor or antenna ring. Any ideas would be appreciated.

Thanks everyone

The whine you are hearing is probably just the brake vacuum pump, nothing that will be causing a no start. Care to pull some codes and we could start there?

Alternator checked out?

If it is the FPS, Napa is the way to go. OEM is really costly, and I got mine for $80. http://www.napaonline.com/Catalog/CatalogItemDetail.aspx/Fuel-Pressure-Regulator/_/R-CRB2260017_0429873670

Just make sure you don't damage the O-Ring when installing, and try & save the old one just in case.

those FPS Fuel Pressure sensors should be replaced every 100K kms. I hope they are making better ones now. I was getting very unnerving "flat spots" on the highway, and was also getting gaps coming off first gear (6 spd) when just starting out. 

 

I googled diagnosed it as the FPS, brought it too a shop, they found a DTC high fuel rail pressure, but not active. Replaced the part, new plugs too, and she runs great, including no more drop after first - second shift. I couldn't wait need the car so had to fork over $250 for the part + labor etc.
