(DFI) chapter)
•
Check that the float moves up and down smoothly without
binding. It should g o down under its own weight.
If the float does not move smoothly, replace the fuel pump
assembly.
•
Using a hand tester [A], measure the resistance across
the terminals in the fuel pump lead connector [B].
Special Tool - Hand Tester: 57001-1394
NOTE
○
In contrast to the normal measuring method, the current
that flows through the gauge when measuring it with a
tester is very low, thus making the measurement easily
affected by the oxidized film of the resistance plate, and
resulting in excessive resistance. Therefore, make sure
to wipe the resistance plate with alcohol before taking a
measurement.
If the readings are not as specified, replace the fuel pump
assembly.
