1994 Volvo 940 ProblemsTransmission Overdrive Relay May Fail
The transmission overdrive relay often fails, preventing the transmission from shifting into overdrive
The fuel pump relay may fail resulting in a "no start" condition, the engine will crank over but will not start and run. Checking for proper fuel pressure would be the first step in diagnosing this concern.
Engine stalling/stumbling problems can be caused by a failing mass air flow sensor.
