2005 S40 won't stay running
hi
I now have my daughters car that she left for me to deal with while she went to Alaska.
2 things that had an issue that I knew of
1. vacuum leak.
2. battery will go dead after 2 days of not driving it. brand new battery!
well it has a 3rd problem that evidently worked it self out before. and it will be a hard sell if I can't fix it.
I can start the vehicle and RPM's are at 1800 and after 5 seconds it stalls as though it runs out of gas, I can get it started most times right back up but same exact behavior.
there are times it will be about 800 RPM's and last may be 30 seconds
I replaced the sensor on the fuel rail with one I pulled from salvage yard. and still the same behavior.
I got a fuel pressure tester which I will try to get some readings.
what am I looking for?
thanks
Paul

My 2005 V50 used to run 55psi (IIRC - it was something in that range, anyway). I never had to work on my Volvo's fuel system (happily) - most modern cars have the fuel pressure regulator in the fuel pump itself - others are external, and may have a vacuum connection (obviously if this is the case, you're going to want to try to figure out that vacuum leak).
