CODE P1171 SYSTEM TOO LEAN BANK 1 PART LOAD. POSSIBLE CAUSE - INTAKE/EXHAUST LEAK , FAULTY MAF SENSOR , FAULTY MAP SENSOR OR FUEL PRESSURE TOO LOW DUE TO STOPPED UP FUEL FILTER.WEAK FUEL PUMP.

has a plastic fuel tank get it checked at repair shop-may have to replace it

Sound like a possible leak or you have a bad injector. You will not be able to lokk under the car for any leaks due the fuel will evaporate, you will need to start the car and look at the fuel rail while it's running. If it is not that check your fuel filters. If your lines do not have addaquate fuel pressue due to a leak or a dirty filter, it could cause those symptoms...


Good luck!

not the pump its the flexible line from metal pipe to the sender unit ,these pipe dont last like they used too and if you look you will see where the pipes have gone porous ,check under bonnet as well on the other ends

this sounds like a gas pressure regulatur. a few minutes after starting,you start smelling fumes,and are getting bad gas mileage right?

I also have a 2004 XC90 and a couple of months ago I had the exact same probelm... after multiple visits to my dealer's auto shop they figured out that it was the fuel pump. They replaced the fule pump and the smell disappeared. Good luck!

its most likely either broke the seal on the halfway of the tank or the fill spout has become damaged and needs replacement. id start by testing the pressure of the tank then deciphering whether or not its the tank or the fill spout.

You should inquire about an extended fuel pump coverage. Volvo has released an extended warranty coverage.
