Is fuel pump heard to operate 3 se-
conds after ignition switch is turned to
ON position?
Fuel pump and its circuit are in good

1) Check fuel pump relay, referring to
FUEL PUMP RELAY of FUEL DE-
LIVERY SYSTEM in this section.
2) Is it in good condition?
Poor fuel pump relay-to-connector
connection, “P” wire open or poor “C4”
connection.
If wire and connection are OK, substi-
tute a known-good ECM/PCM and re-
check.
NOTE:
Before substituting a known-good
ECM/PCM, check to make sure that
