How to Reinstall a Distributor if Crankshaft Moved.

Applys to all Distributor Engines.

Follow this easy instruccions if you want to reinstall a distributor on a vehicle where the crankshaft was moved from the position it was when the distributor was removed.

Remove #1 spark plug

Place your finger over the spark plug hole while turning the engine with a wrench on the pulley bolt at the front of the engine.

When you feel compression continue turning the crankshaft slowly until the timing mark on the vibration damper is aligned with the "0" on the engine timing indicator.

Position the disttributor rotor between the number 1 & 8 (for 8 Cil.) 1 & 6 (for 6 Cil.) or 1 & 4 (for 4 Cil.) spark plug terminals on the cap.

Lower Dist. into engine. To set the gear on the bottom of the distribuitor, you may need to turn the rotor a little bit. If the distributor does not drop down flush against the block is because the distributor shaft has not mated the oil pump shaft, if this happens, place a large socket w/braker bar on the crankshaft bolt and turn the engine over in the normal direction of rotation until the two shafts engage properly and the distributor sits flush against block.

With the base of the distributor properly seated, turn dist. housing to align the marks you made in dist. base and engine block. (you did make this marks before removal right? : )

Place the hold down clamp and install the hold down bolt not too tight.
Install dist. cap an reconect electrical plugs, spark plug wires, etc.

Check ignition timing and when set, tighten dist. hold down bolt.

Can you if so how do you set timing with only using btdc and distributor on a 94 4runner


Ignition timing manual setting 1994 Toyota 4 Runner.
- Remove the distributor cap.
- Pull up the hand brake, place the vehicle in P or Neutral.
- Rotate the crankshaft pulley with a suitable tool to bring the timing mark at 5 degrees BTDC and the reluctor position in front of No. 1 position in distributor.
- Remove the rotor and adjust the distributor (by loosening two distributor locking bolts) in such a way that the No. 1 reluctor tooth just cross the G1 pickup coil notch in the direction of rotation in the distributor.
- Lock the distributor bolts, install rotor and install distributor cap.

wont start no spark


If your engine cranks normally but will not start because it has no spark, or it stalls and won't restart because it has no spark, the problem may be due to any of the following:

A bad pickup inside the distributor (on engines that have a distributor), a stripped distributor drive gear (common problem with plastic distributor drive gears), broken, loose or corroded wires from the pickup to the ignition module orPCM.

A bad crankshaft position (CKP) sensor (on engines that do not have a distributor), or broken, loose or corroded wires from the sensor to the PCM.

A bad ignition module (on engines that have a distributor or use an ignition module separate from the PCM)

A bad ignition coil (on engines that have a distributor and a single coil)

A bad rotor or distributor cap (cracks or carbon tracks that are allowing the spark to short to ground)

Faulty ignition switch.

how to remove distributor on 1994 nissan pathfinder


Hi there:
Check this removal procedure (See Figures 1 through 5)

  1. Disconnect the negative battery cable.
  2. Unfasten the retaining clips (only remove the coil wire if necessary) and lift the distributor cap straight off. It will be easier to install the distributor if the spark plug wiring is left connected to the cap. If the plug wires must be removed from the cap, mark their positions to aid in installation.
  3. Remove the dust cover and mark the position of the rotor relative to the distributor body; then mark the position of the distributor body relative to the engine block.
  4. Detach the harness assembly connector.
  5. Remove the pinch-bolt and lift the distributor straight out, away from the engine. The rotor and body are marked so that they can be returned to the position from which they were removed. Do not turn or disturb the engine (unless absolutely necessary) after the distributor assembly has been removed.

After the distributor assembly has been installed, the rotor should be in this position-VG30i and VG30E engines

INSTALLATIONTiming Not Disturbed

  1. Insert the distributor in the block and align ALL matchmarks made during removal.
  2. Engage the distributor driven gear with the distributor drive.
  3. Install the distributor clamp and secure it with the pinch-bolt.
  4. Install the distributor cap and fasten the harness electrical connector.
  5. If necessary, install the spark plug wires and coil wire.
  6. Start the engine. Check the timing and adjust it if necessary.

Timing Disturbed
  1. It is necessary to place the No. 1 cylinder in the firing position to correctly install the distributor. To locate this position, the ignition timing marks on the crankshaft front pulley can be used.
  2. Remove the No. 1 cylinder spark plug. Turn the crankshaft until the piston in the No. 1 cylinder is moving up on the compression stroke. This can be determined by placing your thumb over the spark plug hole and feeling the air being forced out of the cylinder. Stop turning the crankshaft when the timing marks indicate TDC or 0 .
  3. Oil the distributor housing lightly where the distributor bears on the cylinder block.
  4. Install the distributor so that the rotor, which is mounted on the shaft, points toward the No. 1 spark plug terminal tower position when the cap is installed. Of course, you won't be able to see the direction in which the rotor is pointing if the cap is installed, so lay the cap on the top of the distributor and make a mark on the side of the distributor housing just below the No. 1 spark plug terminal. Make sure that the rotor points toward that mark when you install the distributor.

On the VG30i and VG30E engines, align the mark on the distributor shaft with the protruding mark on the housing.

  1. When the distributor shaft has reached the bottom of the hole, gently move the rotor back and forth slightly until the driving lug on the end of the shaft enter the slots cut in the end of the oil pump shaft and the distributor assembly slides down into place.

On the VG30i and VG30E engines, the distributor rotor tip should be in the 11 o'clock position.

  1. Fasten the distributor hold-down bolt.
  2. Install the spark plug into the No. 1 spark plug hole.
  3. Install the distributor cap and engage the harness electrical connector.
  4. If necessary, attach the spark plug wires and coil wire.
  5. Start the engine. Check the timing and adjust it if necessary.





Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day

5.2L and 5.9L Engines
  1. Disconnect the negative battery cable.
  2. Tag and disconnect the spark plug wires from the distributor cap and coil
  3. Remove the distributor cap retaining hooks or screws and remove the distributor cap.
  4. Note the position of the rotor in relation to the base. Scribe a mark on the base of the distributor and on the engine to facilitate reinstallation.

The distributor must be bright to Top Dead Center (TDC) before removal.
  1. Attach a socket to the crankshaft damper retaining bolt and slowly rotate the engine clockwise until the indicating mark on the crankshaft damper is aligned with the 0 degree mark on the timing chain cover. The distributor rotor should now be aligned to the CYL. NO 1 alignment mark stamped into the camshaft position sensor. If not repeat the process until TDC is achieved.
  2. Disengage the camshaft position sensor connector and remove the rotor.
  3. Unfasten the distributor hold-down bolt and remove the distributor and hold-down clamp.
Other details can find in the Repair Manual ZJ-Secc-8D-Ignition-Systems

Good luck (remember rated this).
