Ok, the first thing you need to do is to verify that the distributor has been properly installed. Here is how to do this.
the number 1 cylinder to Top Dead Center (TDC) of the compression
stroke. The engine front cover has 2 alignment tabs and the crankshaft
balancer has 2 alignment marks (spaced 90 degrees apart) which are used
for positioning number 1 piston at top dead center (TDC). With the
piston on the compression stroke and at top dead center, the crankshaft
balancer alignment mark (1) must align with the engine front cover tab
(2) and the crankshaft balancer alignment mark (4) must align with the
engine front cover tab (3).
- Rotate the crankshaft balancer
clockwise until the alignment marks on the crankshaft balancer are
aligned with the tabs on the engine front cover and the number 1 piston
is at top dead center of the compression stroke.
- Align white paint mark on the bottom stem of the distributor, and the pre-drilled indent hole in the bottom of the gear (3). Notice: The distributor driven gear and rotor may be installed in multiple
positions. In order to avoid mistakes, mark the distributor on the
following components in order to ensure the same mounting position upon
the driven gear 180 degrees out of alignment, or locating the rotor in
the wrong holes, will cause a no-start condition. Premature engine wear
or damage may result.
|• ||The distributor driven gear|
- With the gear in this position, the rotor segment should be positioned as shown for a V6 engine (1) or V8 engine (2).
|• ||The alignment will not be exact.|
the driven gear is installed incorrectly, the dimple will be
approximately 180 degrees opposite of the rotor segment when the gear is
installed in the distributor.|
- Using a long screw driver align the oil pump drive shaft to the drive tab of the distributor.
- Guide the distributor into the engine. Ensure that the spark plug towers are perpendicular to the centerline of the engine.
- Once the distributor is fully seated, the rotor segment should be aligned with the pointer cast into the distributor base.
pointer may have a 6 cast into it, indicating that the distributor is
to be used on a 6 cylinder engine or a 8 cast into it, indicating that
the distributor is to be used on a 8 cylinder engine. |
the rotor segment does not come within a few degrees of the pointer,
the gear mesh between the distributor and the camshaft may be off a
tooth or more. |
|• ||If this is the case, repeat the procedure again in order to achieve proper alignment.|
Notice: Use the correct fastener in the correct location.
Fasteners requiring replacement or fasteners requiring the use of
thread locking compound or sealant are identified in the service
procedure. Do not use paints, lubricants, or corrosion inhibitors on
fasteners or fastener joint surfaces unless specified. These coatings
affect fastener torque and joint clamping force and may damage the
fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the distributor mounting clamp bolt. Tighten
Tighten the distributor clamp bolt to 25 N·m (18 lb ft).
- Install the distributor cap.
- Install two NEW distributor cap screws. Tighten
Tighten the screws to 2.4 N·m (21 lb in).
- Install the electrical pigtail to the distributor.
- Install the spark plug wires to the distributor cap.
- Install the ignition coil wire. The wire must not touch anything like the dip stick. Rubbing will make a ground/short after time of use.
- For V8 engines, connect a scan tool.
- Monitor the Camshaft Retard Offset value. Important: If
the Malfunction Indicator lamp is turned on after installing the
distributor, and a DTC P1345 is found, the distributor has been
