Volvo 780 Problems
"No start" Due to Failed Fuel Pump Relay
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 Due to Mass Airflow Sensor Failure
Engine stalling/stumbling problems can be caused by a failing mass airflow sensor.
Transmission overdrive relay may fail
The transmission overdrive relay often fails, preventing the transmission from shifting into overdrive
Front End May Be Loose When Braking
When braking, a loose feeling from the front end can be caused by worn strut rod bushings. Worn bushings will require replacement. After they are replaced the wheel alignment should be checked.
No Start Due to Failed Engine RPM Sensor
A faulty RPM sensor can cause the Check Engine Light to come on and cause a "No Start" condition.
