Test Step 1. Inspect the Electrical
Connectors and the Harness
Electrical shock hazard. The fuel rail pump sole-
noid uses 63 to 73 volts.
A. Turn the keyswitch to the OFF position.
B. Thoroughly inspect the harness connector
P2/J2 and the suspect connector P532. Refer to
Troubleshooting, "Electrical Connectors - Inspect"
for details.
C. Perform a 45 N (10 lb) pull test on each of the
wires in the solenoid connector P532 and the
connector pins 25 and 26 that are associated with
the fuel rail pump solenoid. Refer to illustration 48.

D. Check the harness for abrasions and for pinch
points from the battery to the ECM. Check the
harness for abrasions and for pinch points from
the key switch to the ECM.
E. Use the electronic service tool in order to perform
a "Wiggle Test". The "Wiggle Test"is used to
identify intermittent connections.
Expected Result:
All connectors, pins, and sockets are completely
coupled and/or inserted. The harness is free of
corrosion, of abrasion, and of pinch points.
Results:
• OK – The connectors and the harness appear to
be OK. Proceed to Test Step 2.
