DTC P0628 (33), P0629 (33)
GENERAL
Fuel Pump
The fuel pump assembly is shown in
. ECM ter-
minals "27" and "28" provide ground to the fuel pump. These
codes will set if:
•
(BN/Y) wire is shorted to 12 volts. This will also cause the
ignition fuse to blow.
•
(BN/Y) wire is shorted to ground. This will cause the fuel
pump to run continuously even when the motor is not
running.
•
Fuel pump motor stalls.

See
.
2.
Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404-B), purple pin probe and patch cord.
3.
If resistance greater than 1 ohm is found between ECM
connector [10] terminal "27" OR "28" and fuel pump con-
nector [86A] terminal "4", but not both, the open must be
repaired but this repair will not correct the concern.
