Fuel Pressure: Testing and Inspection
Fuel Pressure Test
Special Tools Required
-
Fuel pressure gauge 07406-004000A
-
Fuel pressure gauge attachment set 07AAJ-S6MA150
-
Fuel pressure gauge adapter 07VAJ-0040100
1. Relieve the fuel pressure.
2. K20A2 / K20Z1 / K20A3 engines:
Attach the fuel pressure gauge attachment set (A) and the fuel pressure gauge (B) to the fuel line as shown.
3. Start the engine and let it idle.
-
If the engine starts, go to step 6.
-
If the engine does not start, go to step 5.
4. Check to see if the fuel pump is running: remove the fuel fill cap and listen to fuel fill port while an assistant turns the ignition switch ON (II). You
should hear the pump, run for about 2 seconds when the ignition is turned on.
-
If the pump runs, step 6.
-
If the pump does not run, test it.
5. Read the pressure gauge. The pressure should be 320 - 370 kPa (3.3 - 3.8 kgf/sq.cm, 47 - 54 psi).
-
If the pressure is OK, the test is complete
-
If the pressure is out of specification, replace the fuel pressure regulator, and fuel filter, and recheck fuel pressure.
6. Remove the pressure gauge, and reinstall the fuel pulsation damper with a new washer. Tighten the fuel pulsation damper to 22 N.m (2.2 kgf.m,
16 lbf.ft).
NOTE: Disassemble and clean the fuel pressure gauge attachment thoroughly after use.
