What is the fuel pressure at the rail?
Fuel pressure at rail is around 1k … read more Vocational, Technical or Tra… I have a 2017 Land Rover Sport that stalls. 1. The car runs 1. The car runs for a minute if I pump keep my foot on the gas, but eventually dies out. 2. The check engine light comes on.
How is the fuel pressure set in a GM return system?
Fuel Pressure Explained. With a return system, the base pressure is set with the engine off, but the pump running. For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail). The vacuum/boost referenced regulator will help to change the pressure in the rail based on the pressure in the manifold.
How does a return style fuel injector system work?
Return style systems hold a big advantage in that with a vacuum/boost referenced fuel pressure regulator, the system can maintain a CONSTANT effective fuel pressure, which can extend the range of fuel injectors and help them function at lower fuel demands as well.
Why is effective pressure important in fuel injector?
When you stick a fuel pressure sensor on the end of a rail, it is reading the pressure inside of the rail. While this number is important, it is only half of the story. Effective pressure is the actual applied pressure for the injector, and is the pressure differential ACROSS the injector.

What causes the p0088 code on the fuel rail?
This high fuel pressure is detected by the fuel pressure sensor located on the fuel rail. Once the high fuel pressure is detected the ECM causes a Check Engine Light to be seen on the dashboard of the vehicle. P0088 then causes the vehicle to go into a failsafe mode until normal fuel pressure is detected. What causes the P0088 code?
How does a fuel rail sensor check fuel pressure?
This allows us to check fuel pressure at the fuel rail and then use the scan tool to check what the fuel pressure sensor is reading. Both of these readings are needed to test the fuel pressure sensor. An advanced scanner is also needed to monitor fuel pressure sensor data.
What are the trouble codes for fuel rail?
1 Replacement of the damaged fuel lines 2 Faulty fuel pressure sensor replaced 3 Replacement of the fuel pressure regulator
