TESTING

  1. Disconnect the crankshaft position sensor wire harness plug.
  2. Connect an ohmmeter to the sensor terminals A and B and measure the resistance. Fig. 1: Crankshaft position sensor connector terminals. Measure the resistance across the A and B terminals My car got FS engine. it cranks but no spark on - 89544g27.gif
    Fig. 2: Measure the air gap between the crankshaft position sensor and the crankshaft pulley 89544g28.gif

  3. The reading should be 520–580 ohms at 68°F (20°C).
  4. If not as specified, replace the sensor.
  5. Measure the air gap of the sensor between the crankshaft pulley and the sensor.
  6. Proper air gap should be 0.040–0.080 in. (1–2 mm).
  7. If not as specified, inspect the crankshaft pulley and/or replace the sensor.

Why cadillac deville won't start when hot?


Sounds like the module inside the distributor is starting to fail. If the engine turns over at normal speed but won't start then grab a spark checker and put it at the end of a spark plug wire and crank the engine. If if sparks then you have a fuel problem. If no spark then look to the distributor module or possibly the wiring harness inside the distributor. I have seen where the power wire, pink I believe, goes open at the black plastic box connector inside the distributor and can be tested with an ohmmeter. If that is the problem then replace the 2 wiring harnesses that make up the distributor wiring harness because the plastic connector will break apart when trying to remove the terminal and that makes it difficult to put back together. Hope that helps

Truck wont start


Check for spark at the distributor if no spark check or replace coil pack. also check to see distributor is turning while engine cranking, if not, possible worn out or broken gear tooth on shaft inside engine.
if distributor turns, check for burnt or worn out points and/or contacts on distributor cap.

Distributor

ABCDEFGHIJKLMNOPQRSTUVWXYZ

Inspect/Replace

To Remove
  • Disconnect the distributor wiring connector and the vacuum advance hose, if the vehicle is so equipped.
  • Remove the distributor cap and note the position of the rotor. Mark the position on the distributor housing.
  • On some vehicles, it may be necessary to remove the spark plug wires from the cap prior to cap removal.
  • Note the position of the vacuum advance, then remove the distributor holddown bolt and clamp.
  • Pull the distributor from the engine. Most distributors will need to be twisted as they are pulled out of their bore.
  • Once the distributor is removed, install a shop towel in the distributor opening to keep foreign material out of the engine block.
  • The entire assembly should be cleaned thoroughly. Make sure all solvent residue is completely removed.
Installing and Timing a Distributor
The following procedure may be followed to install the distributor and time it to the engine, if all reference marks were made during the removal of the distributor:
  • Lubricate the O-ring on the distributor shaft.
  • Position the rotor so that it is aligned with the mark made on the distributor housing prior to removal.
  • Align the distributor housing with the mark made on the engine block during removal.
  • Lower the distributor into the engine block, making sure the distributor drive is fully seated.
  • Distributors equipped with a helical drive gear will rotate at the distributor is being installed, causing the distributor to move away from the reference marks.
  • Pay attention to how much the rotor moves.
  • Remove the distributor and move the rotor backward the same amount. This should allow the shaft to rotate while the distributor is being installed and still be aligned with the reference marks.
  • Make sure the distributor housing is fully seated against the engine block. Sometimes it may be necessary to wiggle or rock the distributor to seat it fully into the drive gear.
  • Distributors with drive lugs must be mated with the drive grooves in the camshaft. Both are offset to eliminate the possibility of installing a distributor 180 degrees out of time.
f22-52.gif The distributor must be aligned with the camshaft drive to seat the distributor in the engine block or cylinder head.
  • Rotate the distributor a small amount so the timer core teeth and pick-up teeth are aligned.
  • Install the distributor holddown clamp and bolt, leaving the bolt slightly loose.
  • Install the spark plug wires in the direction of distributor shaft rotation and in the cylinder firing order.
  • Connect the distributor wiring connectors. The vacuum advance hose is usually left disconnected until the timing is set with the engine running.
If the engine has been cranked while the distributor is removed, or no marks were made during removal, use this procedure to reinstall the distributor:
To be sure that the number one cylinder is on its compression stroke, observe the rocker arms to see that they are both moving. Then, rotate the crankshaft one revolution until the rocker arms for the companion to cylinder number one are both moving at TDC (top dead center). Align the timing mark and install the distributor with its rotor pointing to the number one spark plug cable in the distributor cap.

  • Remove the spark plug from cylinder #1. Install a test plug in the end of the spark plug wire and position the test plug away from you and cylinder #1.
f22-02.jpg
  • Place your thumb over the bore for the spark plug and crank the engine until compression is felt.
f22-03.jpg
  • Lightly crank the engine while observing the timing marks on the crankshaft pulley. Once the timing marks are aligned, stop cranking.
f22-04.jpg
  • Identify the position for the #1 spark plug wire on the distributor cap.
f22-05.jpg
  • Determine which way the distributor shaft will rotate when it is lowered onto the camshaft gear. Then position the rotor so that it will be under the #1 terminal on the distributor cap after the distributor gear is meshed with the camshaft gear.
f22-06.jpg
  • After the distributor is installed in the engine, turn the distributor housing slightly so the pickup coil is aligned with the reluctor.
f22-07.jpg
  • Install the distributor holddown clamp and bolt. Hand tighten the bolt.
f22-08.jpg
  • Connect the pickup leads to the wiring harness.
f22-09.jpg
  • Install the spark plug wires onto the distributor cap according to the engine's firing order. Check to make sure everything that was disconnected before the distributor was removed, is now connected. Connect a timing light and prepare the engine for an ignition timing check and adjustment.

I have installed a new distributor and lost the right crank position. I cranked the engine to TDC but after replacing the distributor back in facing the #1 cylinder I attempted to start it but didn


I am not sure about your model but for a six cylinder firing order usually is 153624. Since you said that before removing the old distributor you cranked the engine to TDC and on fitting the new distributor you should put the rotor in position of cylinder 1 and to be fitted on the correct advance position.But you said that you don't have any spark you mean from the distributor to the spark plugs? If so is not your timing marks but something is wrong wit the connector to distributor or the coil or distributor itself. Carry furthe checks about if you can or ask an expert to do so.

Stopped at store. Came out....engine cranks but not starting....checked for spark....none


Did you check your fuses in fuse compartment. Did your ever check the supply voltage of the distributor if no voltage check loss connector and fuse blown. If the voltage ok. Check the high voltage transformer if no high voltage check loss connectors, 12 volt supply may be missing or the resistor is open. The problem only circulate on this distributor system.

I have a 1998 durango, I have no spark from disturbtor but have spark from coil


Replace the distributor cap and rotor. If you have fire from the coil but not from the distributor cap, you have a bad contact point between the cap and rotor. Replace both and you should be good to go,, if the information that you have supplied is correct.

Motor turns over but no spark changed coil and crank shaft sensor


well replace lots of coils but same with crank sensor on these trucks
  • For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. To perform a complete test of the Camshaft Position Sensor and its circuitry, refer to the DRB II diagnostic tester. Also see the appropriate Diagnostic Charts. To test the sensor only, refer to the following: See: Testing and Inspection
  • Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips.
PROCEDURE
  1. Connect the positive (+) voltmeter lead into the sensor output wire. This is done at the distributor wire harness connector.
  2. Connect the negative (-) voltmeter lead into the ground wire.
  3. Set the voltmeter to the 15 Volt DC scale.
  4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup.
  5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts .
  6. If voltage is not present, check the voltmeter leads for a good connection.
  7. If voltage is still not present, check for voltage at the supply wire.
  8. If voltage is not present at supply wire, check for voltage at pin-7 of Powertrain Control Module (PCM) 60-way connector. Leave the PCM connector connected for this test.
  9. If voltage is still not present, perform vehicle test using the DRB II diagnostic scan tool.
  10. If voltage is present at pin-7, but not at the supply wire:
    1. Check continuity between the supply wire. This is checked between the distributor connector and pin-7 at the PCM. If continuity is not present, repair the harness as necessary.
    2. Check for continuity between the Camshaft Position Sensor output wire and pin-44 at the PCM. If continuity is not present, repair the harness as necessary.
    3. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary.
  1. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. NOTE: If sync pulse signal is not present, replacement of the Camshaft Position Sensor is necessary.
