Low Fuel Pressure
Check for Low Fuel Pressure causing a No Start condition as follows:
- Turn the ignition on, crank the engine over, and check the DDR or DDDL for fuel pressure.
- If the fuel pressure is above 649 kPa-a (94 psia) (CNG) or above 511 kPa-a (74 psia) (LNG), then check PSV operation. Refer to "3.6.1 PSV Operation Check"
- If there is no fuel pressure or the fuel pressure is below 649 kPa-a (94 psia) (CNG) or 511 kPa-a (74 psia) (LNG), then check the operation of the Low Pressure Fuel Shut-Off Valve. Refer to "3.5.1 Low Pressure Fuel Shut-Off Valve Check"
