Fuel Pressure
CAUTION:
Constant fuel pressure is maintained in fuel lines and component parts at all times. Relieve pressure before attempting to open system for testing. Do not allow fuel to flow onto engine or electrical parts or allow an open flame in area while testing fuel system components.
- To relieve fuel system pressure, unplug fuel pump connector and crank engine more than 5 seconds. Run engine until it stalls. Disconnect fuel hose at pressure regulator and install fuel pressure gauge using "T" fitting.
- Start engine and check fuel pressure at idle. Fuel pressure should be 26-30 psi (1.8-2.1 kg/cm2 ). Increase engine RPM and make sure fuel pressure increases correspondingly.
