fusible link, fuses, EFI MAIN relay, fuel pump, ECM and wiring connections.
f. Turn the ignition switch to LOCK.
g. Disconnect the hand-held tester from the DLC3.
2.CHECK FUEL PRESSURE
a. Check that the battery positive voltage is above 12 V.
b. Disconnect the negative (-) terminal cable from the battery.
c. Remove the fuel pressure pulsation damper from the RH delivery pipe (see REPLACEMENT
).
d. Install the fuel pipe sub-ass
y No. 2 and SST (pressure gauge) to the delivery pipe with the 3 lower
