NOTES

•

Do not install sensors that have been dropped or impacted
by other components. Damage to the sensing element
may have occurred. Replacement sensor assemblies have
threads coated with anti-seize lubricant and new seal
rings.

•

If reinstalling the O2 sensor, apply a thin coat of ANTI-
SEIZE LUBRICANT (Part No. 98960-97) to threads of
each oxygen sensor prior to installing in header. Do not
use any other grease or sealant product on sensor threads.
The electrical connector must also be clean and free of
any dielectric grease.

If sensor is being reinstalled, replace seal ring and coat
threads on sensor with LOCTITE ANTI-SEIZE.

Thread sensor into threaded boss on exhaust pipe and
tighten to 29-44 ft-lbs (39.3-59.7 Nm).

NOTE

Ensure both connector halves are clean and free of any
dielectric grease. Never use dielectric grease on sealed con-
nectors.

Route sensor harness to mating connector and connect.
Install cable straps that were removed during removal.

Repeat above for other sensor.

FUEL PUMP

GENERAL

When servicing the fuel system, do not smoke or allow
open flame or sparks in the vicinity. Gasoline is extremely
flammable and highly explosive, which could result in
death or serious injury. (00330a)

Carefully inspect hose for cuts, tears, holes or other damage.
Replace hose if any damage is found. Even a small hole can
cause a reduction in fuel pressure.

Refer to the electrical diagnostic manual for information on the
function and testing of the fuel pump.

REMOVAL

To prevent spray of fuel, purge system of high-pressure
fuel before supply line is disconnected. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00275a)

Purge the fuel supply line of high pressure gasoline.

See

Figure 4-33

. Remove the fuel pump fuse from

fuse block.

Start the engine and allow the vehicle to run.

When the engine stalls, operate the starter for 3
seconds to remove any remaining fuel from the fuel
lines.

sm02188

Figure 4-33. Fuel Pump Fuse

To prevent accidental vehicle start-up, which could cause
death or serious injury, disconnect negative (-) battery
cable before proceeding. (00048a)

Disconnect negative battery cable.

Remove instrument console.

7.19 FUEL GAUGE

Disconnect console wiring.

Gasoline can drain from the crossover line when discon-
nected from fuel tank. Gasoline is extremely flammable
and highly explosive, which could result in death or ser-
ious injury. Wipe up spilled fuel immediately and dispose
of rags in a suitable manner. (00259a)

Drain fuel tank.

Obtain a short section of hose (5/16 inch I.D.). Insert
bolt in one end of hose and install hose clamp to verify
that end is securely plugged.

See

Figure 4-34

. Cut clamp (1) from one end of

crossover hose (2). Quickly replace crossover hose
on fuel tank fitting with open end of short hose while
directing flow of gasoline from free end of crossover
hose into suitable container.

See

Figure 4-35

. Unplug fuel pump and sender connector

(1) [141].
