'02 V70 Turbo w/126K cranks and cranks and then starts

[skisix38off]

Last weekend I went out to the car with pressure gage in hand and found no pressure, 0, on the fuel rail. I thought I was actually doing something wrong, or in the wrong spot. I turned the key to the "on" position and got out and walked to the front of the car and the fuel pump was still pumping( indicated by the buzzing of it). I checked the same spot and was showered with gas. I think that's a positive indication that the fuel pressure regulator is the problem. Concur?

Hi, New to MVS and am very grateful for everyones posts.

I have a 2002 V70 XC w/124,000 on it and had the same problem. No CEL came on but had "reduced engine performance" about 2-3 times a week and more oftern when warmer out. Had to take to dealer for service and mentioned it to them. Pulled codes that only they could read from memory.

Turns out that it was the RPM(aka crank sensor) that is located just below the cam sensor area. It is under all the turbo hoses and wiring harnesses. Tech pulled it our and showed me what appeares to be 124,000 miles worth of starter/flywheel wear that collected on the magnetic sensor. Aparently all the little metal pieces built up enough to cause intermitent signal problems. He recommended cleaning it and blowing out the area while it was out to reduce likely hood of it happening again.

After removing, cleaning, reinstalling, clearing all other codes car cranks fine every time. This was the most expencive($230) cup of Coffee and carwash I ever had but at least the car works properly again. Hope this helps if you havent found the cause yet.

That's a helpful tip, sounds like I ought to find this sensor and clean it regardless of whether that's my problem...

Do you have a picture of this sensor or a more precise location that I can go look for?

Thanks!

No
What you do is go to a Volvo dealer and get them to pull the stored codes.
If you want an aftermarket check valve, I sell them for $85 shipped.
This is usually a 2000 issue not a 02-03 issue, but of course anything is possible

JRL, is there a fuel pump check valve for an 03 S60 2.3

[JRL]

ALL fuel pumps and systems have check valves, that's how they work.
What I sell is generic, will work with any car
