I've been chasing this around in circles. I've replaced the cam position sensor on my 1993 850, and still keep stalling. Four non-starts after short trips plus two died-on-road.
The last non-restart had me trying to listen for the sound of the fuel pump going. Ever tried that at a busy gas station and you're the only person in the car.
In my attempts at the last one, I found that I got a trickle of fuel for some start attempts. Just enough to have the engine turn over at idle but it would die instantly when I touched the gas pedal. Engine was running just a touch ragged but not excessively so.
The guys at the shop are talking fuel pump, but I'm thinking relay first because everyone here who has been having similar problems on their 1990's 850 and 960 cars have been commenting that the relay goes more than the fuel pump.
Also, the books that I have do not show where the 850 fuel pump relay is located.
Is it in the box along with the fuses but hidden up against the dash side?
Thanks muchly.....
