Section 1.4
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 94 psia (649 kPa-a) (CNG) or above 74 psia (511 kPa-a) (LNG), then check PSV operation. Refer to "1.6.1 PSV Operation Check"
.
- If there is no fuel pressure or the fuel pressure is below 94 psia (649 kPa-a) (CNG) or 74 psia (511 kPa-a) (LNG), then check the operation of the Low Pressure Fuel Shut-Off Valve. Refer to "1.5.1 Low Pressure Fuel Shut-Off Valve Check"
.
- If the engine still does not start, check the Fuel System. Refer to "1.5 Fuel System"
.
- If the engine starts, troubleshooting is done.
