1. Install Fuel Pressure Gauge (49 UN01 010) to fuel pressure relief valve (Schrader valve) located on fuel rail. Place fuel pressure gauge drain hose in suitable container and press pressure relief button until fuel pressure is released.
2. If fuel pressure gauge is not available, disconnect inertia fuel shutoff switch connector. Switch is located under instrument panel, right of transmission hump. Crank engine 15-20 seconds to relieve pressure. Reconnect inertia fuel shutoff switch.

1. Disconnect negative battery cable. Install fuel pressure gauge in fuel supply line. Reconnect negative battery cable.
2. Locate data link connector in left side of engine compartment. Connect a fused jumper wire between data link connector terminals F/P and GND. (Scheme 12) Turn ignition on for 10 seconds to operate fuel pump. Turn ignition off and disconnect fused jumper wire. Wait 5 minutes and observe fuel pressure. See «FUEL PRESSURE HOLD»(ref-11545-S08229472962001061400000) table.
3. On MPV, if fuel pressure is not as specified, check for leaks and fuel pressure regulator. On all other models, if fuel pressure is not as specified, check fuel pump hold pressure and fuel pressure regulator hold pressure. See «FUEL PUMP HOLD PRESSURE»(ref-11545-S26131190912000111700000) and «FUEL PRESSURE REGULATOR HOLD PRESSURE»(ref-11545-S12773970352000111700000). Also check for injector fuel leakage. See «INJECTOR FUEL LEAKAGE»(ref-11545-S41444430562000111700000).
