Before using the following flow table, check to make sure that battery voltage is higher than 11 V. If
battery voltage is low, pressure becomes lower than specification even if fuel pump and line are in
good condition.
Step Action Yes No
1 1) Install fuel pressure gauge, referring to

(2.7 – 3.1 kg/cm
2
, 38.4 – 44.0 psi)?
