CID 1779 FMI 08
Conditions Which Generate This Code:
This diagnostic code indicates that the signal to the solenoid for the fuel rail pump is abnormal.
System Response:
A warning will appear on the display on the control panel. If equipped, the diagnostic lamp will flash the diagnostic code. The ECM will log the diagnostic code.
An erratic signal may prevent the provision of pressure to the fuel rail. This may result in the loss of fuel injection. If the solenoid for the fuel rail pump fails, it is likely that fuel will not be pumped into the fuel rail. The engine will stop or the engine will not start.
Test Step 1. Perform the following diagnostic procedure: Fuel Rail Pump Solenoid - Test
Results:
- OK - STOP
