FLA -302 FUEL SYSTEM ▶ Blocking in intake manifold and injector caused by any foreign substance 2) Has a problem found? YES ▶ Repair or replace it, and go to "Verification of Vehicle Repair" procedure. NO ▶ Go to " Check fuel pressure" as follows. 2. Check fuel pressure NOTE - Be cautious that Fuel is explosive and an empty fuel tank can still contain explosive gases.When working on fuel - The fuel system remains under pressure when the engine is not running. Release fuel systempressure before 1) Start the engine and disconnect the fuel pump relay. 2) Wait until fuel in fuel line is exhausted and the engine stalls. 3) Turn the ignition switch OFF position. 4) Install the special service tool for measuring the fuel pressure between the delivery pipe and the fuel feed hose. 5) Connect the fuel pump relay. 6) With fuel pressure applied, check the three is no fuel leakage from the fuel pressure gauge or connection part. 7) Start the engine and measure the fuel pressure at idle. Specification : 374 ~ 384 kpa (3.82 ~ 3.92 kg/㎠, 54.3 ~ 55.8psi) 8) Stop the engine and check for a change in the fuel pressure gauge reading. Specification : After engine stops, the gauge reading should hold for about 5 minutes. 9) Is the measured fuel pressure within specification? YES ▶ Go to "Check fuel leakage in injector" procedure. NO ▶ Repair or replace according to the table below. |
