(1) Inspect change in the fuel line pressure while turning the lever as shown.
-
If the fuel line pressure quickly increases, inspect the pressure regulator.
-
If fuel line pressure gradually increases, inspect the fuel pump maximum pressure.
-
If the fuel pump maximum pressure is normal, inspect for clogging between the fuel pump and the pressure regulator.
8. Turn off the ignition switch and disconnect the jumper wire
9. Observe the fuel pressure after 5 min. If the fuel hold pressure is lower than specified, proceed to step (1).

(1) Inspect changes in the fuel line pressure while turning the lever as shown.
-
If the fuel line pressure holds, replace the pressure regulator.
-
If the fuel line pressure does not hold, inspect the fuel leaks from the fuel line and the fuel injector.
10. Disconnect the SST.
NOTE: A checker tab is integrated with the quick release connector for new plastic fuel hoses. The checker tab will be released from the quick
