Hello again,

well I'll tell you that I'm a Volvo owner, S60, 2.5T, 2007, and I'm having troubles when starting at anytime, cold or hot.
I've red that maybe it's the FPR (fuel pressure regulator), or vacuum pipes, etc.
So first of all, please tell me where to find the FPR please. I checked the car and couldn't find this regulator

Thanks

 

not sure your model has a regulator - probably has a fuel pressure damper which hides under the fuel rail but that normally creates stumbles not starting issues. Have you tested fuel pressure? Can you hear the pump kick on with the key? Have you checked the Fuel pump relay? I'd also consider ignition issues - wires/coils problems? Is the check engine light on or have you tried to pull OBD2 codes?

 

Thanks for your reply. Regarding your comments, I don't hear anything strange when turning the key...just the normal sound for a few seconds.

Update... somewhere I red that the throttle body sometimes gets dirty and may cause starting problems. So they recommend to clean it and check every air hoses... So I did that yesterday and I'm testing now...
Until now I haven't had problems when starting...
I'll let you know

Thanks

 

There is no regulator.
