I just bought a Volvo 850 wagon. I knew that the car had trouble and I got a great deal on it expecting some work to do. My dad and i were told that it needed an Air intake master sensor. we checked it and it seemed fine, and did some reading up online, and then checked Cam position sensor, Crankshaft position sensor and both are fine. we discovered that there is no spark going to the coil, and no power going to the fuel pump each of which we checked and seem to be fine. the last problem we found is that none of the gauges and lights in the dash are not getting power (all the fuses are good), external lights, radio, sunroof and windows all work fine. We did put a newer battery in the car, it turns over fine and did run before sitting for 2 years after a stalling issue that the previous owner didn’t want to bother fixing.
the car has 140K on it and is in good condition, my dad has owned and worked on many Volvo’s over the years and is very confident in working on them but we are both very puzzled about the lack of power going to the coil and fuel pump.
thanks for any help,
