I have intermittent stalling problems with my 1993 volvo 240 wagon, under all conditions, for over 3 months. The car will start approximately 1 minute after it stalls. The "check engine light" has been on, and remains on. I have replaced the fuel filter, cap and rotor, plugs & wires and throttle sensor. I put a fuel gauge on the fuel injection rail to see if the pressure would change when the car stalled. It did not change, it maintained 32 lbs of pressure. I feel it eliminated a fuel problem, and am thinking of replacing the crank sensor. Can anyone suggest how to go about replacing it, or does anyone have other suggestions for this problem? Thanks for your input.
