Is the measured fuel pressure value within the specification?
 | ▶ Go to "Fuel remain pressure inspection" procedure as below. |
 | ▶ Repair or replace fuel filter and fuel hose. (whether it is blocked or not) |
Measure the fuel pressure at idle after installing a fuel pressure gauge to delivery pipe.
☞ Install a fuel pressure gauge after combustion in the fuel line by removing fuel pump relay.
■ Specification : 3.3~3.7㎏f/㎠ (324 ~ 363㎪, 46.9 ~ 52.6psi)
Is the measured fuel pressure value within the specification?

| ▶ Repair or replace fuel filter and fuel hose. (whether it is blocked or not) |
Monitor fuel pressure at fuel pressure inspection as above.
Engine "STOP"
Check decrease in fuel pressure.
■ Specification : After engine stops, the gage reading should hold for about 5 minutes.
Does the fuel pressure remain after engine stop?
