Fuel Pressure Test
Special Tools Required
Fuel pressure gauge ( 07406-0040002)
Fuel pressure gauge attachment ( 07VAJ-0040100)
Fuel pressure gauge set ( 07ZAJ-S5A0100)
|1.||Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.|
|2.||Disconnect the negative cable from the battery.|
|3.||Remove the fuel fill cap and the engine cover.|
|4.||Use a wrench on the fuel pulsation damper (A) at the fuel rail.|
|5.||Place a rag or shop towel (B) over the fuel pulsation damper.|
|6.||Slowly loosen the fuel pulsation damper one complete turn.|
|7.||Remove the fuel pulsation damper from its fitting, and attach the fuel pressure gauge attachment.|
|8.||Attach the fuel pressure gauge.|
|9.||Start the engine and let it idle.|
- If the engine starts, go to 11.
- If the engine does not start, go to 10.
|10.||Check to see if the fuel pump is running: listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned ON (II).|
|11.||Read the pressure gauge. The pressure should be 330-380 kpa (3.4-3.9 kgf/cm2, 48-55 psi) (KZ model: 320-370 kpa (3.3-3.8 kgf/cm2, 47-54 psi))|
|12.||Remove the pressure gauge, and reinstall the fuel pulsation damper with a new washer. Tighten the fuel pulsation damper to 22 N·m (2.2kgf·m, 16 lbf·ft) [KT, KP, KW, IN models: 27 N·m (2.8 kgf·m, 20 lbf·ft)].|
NOTE: Disassemble and clean the fuel pressure gauge attachment thoroughly after use.
