1999 DODGE RAM engine

Installation
1) If installing injector on fuel rail, install NEW "O" ring
on injector. Coat "O" ring on injector with engine oil. Install
injector on fuel rail. Position injectors on fuel rails so electrical
connector on injector is facing toward passenger's side of the
vehicle. Install retaining clip on injector and fuel rail.
2) To install remaining components, reverse removal procedure
using NEW "O" ring at bottom of each injector. Coat "O" ring on
injector with engine oil before installing injectors and fuel rails.
3) Push passenger's side fuel rail and then driver's side
fuel rail downward until shoulder on each injector contacts the intake
manifold. Ensure all injectors are fully seated.
4) Tighten fuel rail bolts to specification. See TORQUE
SPECIFICATIONS. Using NEW gasket, install upper intake manifold with
all bolts loosely installed. Tighten upper intake manifold bolts to
specification in sequence. See Fig. 39. See TORQUE SPECIFICATIONS.
5) Tighten throttle body nuts to specification. See TORQUE
SPECIFICATIONS. Install fuel line on fuel rail using proper procedure.
See FUEL LINE AT FUEL RAIL. Start engine and check for leaks.

THROTTLE BODY
Removal & Installation (Dakota, Durango, Ram Pickup 3.9L,
5.2L & 5.9L, Ram Van & Ram Wagon)
On Ram Van and Ram Wagon, remove engine cover. On all models,
remove air inlet duct or air cleaner from throttle body. Disconnect
electrical connectors, control cables and vacuum hoses at throttle

Removal (Dakota & Durango)
1) EVAP leak detection pump and EVAP leak detection pump
filter must be replaced as an assembly. EVAP leak detection pump is
located at driver's side of engine compartment, just below battery
tray. See Fig. 40. EVAP leak detection pump filter is attached to
outside of battery tray, just in front of power distribution center.
See Fig. 40 .
2) Remove battery. Disconnect hose from bottom of EVAP leak
detection pump filter that goes to EVAP leak detection pump. Remove
retaining clip and disconnect EVAP leak detection pump filter from
battery tray.
3) Disconnect wiring harness for battery temperature sensor
from bottom of battery tray. Power distribution center must be removed
for access to EVAP leak detection pump.
4) Remove power distribution center-to-fender retaining screw
at rear of power distribution center. Unsnap power distribution center
from battery tray. Carefully position power distribution center aside.
5) Remove battery tray. Disconnect electrical connector and
vacuum hoses at EVAP leak detection pump. Use care not to damage
vacuum hoses during removal. Remove retaining bolts and EVAP leak
detection pump.
NOTE: Vacuum hoses and hose to EVAP leak detection pump filter must
be properly installed on EVAP leak detection pump and all
hoses must be in good condition. If hoses are not properly
installed or are damaged, a Diagnostic Trouble Code (DTC)
will be set in the Powertrain Control Module (PCM).
Installation
1) Install EVAP leak detection pump on battery tray. Tighten
retaining bolts to specification. See TORQUE SPECIFICATIONS.
2) To install remaining components, reverse removal
procedure. Ensure vacuum hoses and hose to EVAP leak detection pump
filter are in good condition and properly installed on EVAP leak
detection pump.

leak detection pump. Use care not to damage vacuum hoses during
removal. Remove retaining bolts and EVAP leak detection pump.
NOTE: Vacuum hoses and hose to EVAP leak detection pump filter must
be properly installed on EVAP leak detection pump and all
hoses must be in good condition. If hoses are not properly
installed or are damaged, a Diagnostic Trouble Code (DTC)
will be set in the Powertrain Control Module (PCM).
Installation
1) Install EVAP leak detection and EVAP leak detection pump
filter. Tighten retaining bolts to specification. See TORQUE
SPECIFICATIONS.
2) To install remaining components, reverse removal
procedure. Ensure vacuum hoses and hose to EVAP leak detection pump
filter are in good condition and properly installed on EVAP leak
detection pump.
Removal (Ram Van & Ram Wagon)

purge solenoid. Use care not to damage vacuum hoses during removal.
Remove EVAP purge solenoid from mounting bracket. Disconnect
electrical connector and vacuum hoses at EVAP leak detection pump. Use
care not to damage vacuum hoses during removal.
3) Remove retaining bolts from mounting bracket. Remove
mounting bracket with EVAP leak detection pump and EVAP leak detection
pump filter as an assembly. Remove retaining bolts, EVAP leak
detection pump and EVAP leak detection pump filter from mounting
bracket.
NOTE: All vacuum hoses and hose to EVAP leak detection pump filter
must be properly installed on EVAP leak detection pump and
all hoses must be in good condition. If hoses are not
properly installed or are damaged, a Diagnostic Trouble Code
(DTC) will be set in the Powertrain Control Module (PCM).
Installation
1) Install EVAP leak detection and EVAP leak detection pump
filter on mounting bracket. Tighten retaining bolts to specification.
See TORQUE SPECIFICATIONS.
2) To install remaining components, reverse removal
procedure. Ensure vacuum hoses and hose to EVAP leak detection pump
filter are in good condition and properly installed.

NOTE: EVAP purge solenoid may also be referred to as EVAP canister
purge solenoid, duty cycle solenoid or proportional purge
solenoid.
Removal & Installation (Dakota & Durango)
1) On Dakota 2.5L, EVAP purge solenoid is located on firewall
at passenger's side of engine compartment. See Fig. 43. On Dakota 3.
9L, 5.2L and 5.9L and Durango, EVAP purge solenoid is located at
driver's side of engine compartment, near brake booster. See Fig. 44.
2) On all models, disconnect electrical connector and vacuum
hoses at EVAP purge solenoid. Use care not to damage vacuum hoses
during removal. Remove retaining nuts and EVAP purge solenoid.
3) To install, reverse removal procedure. Tighten retaining
nuts to specification. See TORQUE SPECIFICATIONS. Ensure vacuum hoses
are in good condition and properly installed.
