Fuel Pressure Testing: RSX
- Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE
. Connect Fuel Pressure Gauge (07406-0040001). Remove pulsation damper and connect Fuel Pressure Gauge (07406-004000A) in its place. (RSX with K20A2 engine, requires use of Fuel Pressure Gauge Attachment (07VAJ-S5A0100) to install fuel pressure gauge.) See Fig 1
. Reconnect negative battery cable. Disconnect and plug fuel pressure regulator vacuum hose. Observe fuel pressure on gauge. See REGULATED FUEL PRESSURE
table. If vehicle will not start, check fuel pump operation. Remove fuel filler cap and listen for fuel pump operation at fill port while an assistant turns ignition switch on. You should hear fuel pump running for about 2 seconds when ignition is turned on. If fuel pump runs, go to next step. If fuel pump does not run, check fuel pump. See FUEL PUMP CIRCUIT TESTING

table. If fuel pressure is okay, go to next step. If fuel pressure is not within specification, replace pressure regulator and fuel filter. Recheck fuel pressure. If fuel pressure is okay, go to next step.
- Turn ignition off. Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE
. Remove fuel gauge. Reinstall fuel pulsation damper with a NEW washer and tighten to 16 ft. lbs. (22 N.m).
