The real issue with diagnosing a bad fuel pump is that it resembles many other vehicular issues in terms of symptoms.

Sometimes when there is low fuel pressure, you may also get an oxygen sensor related trouble code as well. Any trouble codes that exist could be a clue. This trouble code detects that the fuel rail/system pressure is too low. The engine may throw a P0087 trouble code. Before taking anything apart, check to see if your engine’s computer has any trouble codes saved in it. There are physical signs that you can feel when your Expedition ‘s fuel pump is going out. The bad news is that they cost a lot in terms of labor to repair and replace. The good news is that fuel pumps are inexpensive. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to. It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do. In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail(s). With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all. Without gas your Expedition will not run at all. If your Ford Expedition ‘s fuel pump goes bad, no fuel (or not enough fuel depending on whether or not it’s out all the way) can enter the engine. The control module will look at ambient temperature and other factors to determine when and how long the compressor should run to manage the heat.One of the worst problems that can happen to a vehicle is a bad fuel pump. The VDM control modules regulate how long the compressor will run to keep temperatures in a designated range. The system is dry and no lubricants protect the piston. What hastens the failure of the piston ring is heat. The heart of an air ride system is the piston, piston ring and cylinder. The ride height is measured and the scan tool can vent or fill the correct bag. To do this the vehicle must be on a level surface. Not calibrating the ride height can result in suspension and tire damage. The Expedition’s ride height and trim can be calibrated with a scan tool. Some new vehicles, like GM, have a calibration process for the ride control system. Some enhanced scan tools can observe PIDs for the air ride system like valve operation, modes and vehicle position. Scan tools are essential for working on some systems. Criteria for these codes typically involve a ride height sensor detecting to change in suspension height if the compressor or solenoids are activated. The system will set C- or chassis codes that will be set if the system notices abnormal behavior. If you are just replacing the air spring, make sure the body of the shock is very clean. These help to seal the unit from outside debris. The o-rings on the shaft and upper mount should always be replaced and lubricated with a silicone-based spray lubricant. To deflate the spring, remove the air line from the solenoid, remove the retaining clip and rotate the solenoid counter-clockwise. Make sure you know the orientation of the upper mount and air spring before you take the assembly apart. The air bag and shock absorber can be separated. Press the RESET control to turn the air suspension OFF or ON.Select the AIR SUSPENSION function to display the current status of the air suspension system.

When the driver elects to disable the air suspension system, the message center sends a message over the High Speed Controller Area Network (HS-CAN) bus to the air suspension module. The message center is used to disable and enable the vehicle air suspension system. The system will also notify the driver of potential vehicle problems with a display of system warnings followed by a long indicator chime. Select display features on the message center for a display of sta tus proceeded by a brief chime.
The message center is located on the instrument cluster and displays important information through a constant monitoring of vehicle systems. Before starting any work, you need to disable the system through the message center.
