Fuel Pressure Diagnostic Service
Use a scan tool that can look at special direct fuel injection parameters and perform bidirectional tests.
Fuel Pressure Diagnostics
Direct injection pressure is measured with sensors, and the signals are used to determine pump speed and/or volume.
Fuel Tanks and Pumps
The behavior of the fuel wells, pumps & sending units are often misdiagnosed, leading to fuel pumps being replaced.
