Question about 1996 Saturn SW

1 Answer

Saturn 1996/ no spark

Posted question and got response that the problem may be with the crankshaft sensor. I can't find it or a schematic or diagram. Any help? Starter is fine, all fuses checked and fine, fuel is flowing but no spark in any of the plugs? Where would your money be: Coil, crankshaft sensor or somewhere else? Thank you for your time and help

OBD will not pass on saturn.It tells me I need a camshaft position sencer.My garage doesnt want to mess with it.Where is this item located and is it an easy replaced piece?


The 4 cylinder engine in your 1996 Saturn SL doesn't use a cam sensor. I know, then how could there be a code for the cam sensor? Well, The electronic ignition (EI) module supplies a signal to the PCM whenever it determines that the #4 cylinder fired on its compression stroke.

You should start by checking to make sure your spark plug wire terminals on the ignition coils are not corroded. Using a multimeter, check the resistance and continuity of each ignition wire. If your car is misfiring, replace your spark plug wires and have the code cleared at your local AutoZone or Advance Auto, unless you have a code scanner.

If the code comes back, most likely you have a bad crankshaft position sensor throwing the code. While the engine is running there should be a +5 volts on the crank sensor everytime the magnetic pickup reads the crankshaft. Using a multimeter you can check the voltage to see if the sensor is functioning properly.

1996 dodge grand caravan 3.3 will turn over but will not crank seems to be no fire to the plugs


It is hard to say with the info posted, it could be related to a number of issues. If you have verified that there is no spark to the spark plugs, it could be the CPS (crankshaft position sensor)

My saturn 2000 ls2 will turn over but it won't start. I checked the air and fuel filters and the fuel pump is working.


check that you have signal at the crankshaft sensor,also check for spark at the spark plugs.

I have a s10 blazer, with no spark and ignition coil, i replaced the coil and the distributor and there is still no spark, can you tell me what else could that be? I checked for the crank censor but i...


hi, no spark sounds like you really should go find that crankshaft sensor! it is located on the front of the engine right behind the harmonic balancer. it is a three wires sensor that will likely be covered in oil from the front of the oil pan gasket leaking onto it(just that everyone of em i've seen looks like this). you will need to remove the front skid plate to find. after that, just one 10mm head bolt to remove. if you find it tests good, or replace it, and still no spark, it will be time to get out a wiring schematic and start hunting down powers and grounds, and computer control circuits. there is not much more than a crankshaft sensor, distributor, ignition coil, and wiring/computer in the ignition circuit.

I needto know how to replace a Crankshaft postion sensor A circuit


      • The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft.
      • A crankshaft adjusting tool may be used to check these rings
      place the tool on the pulley extension surface and rotate the tool around the pulley.
    • If any blade touches the tool, replace the pulley.
  • Inspect the trigger wheel behind the crankshaft pulley and the sensor for damage.
  • If the engine misfires all the time or on acceleration only, test the following components:
    • Engine compression.
    • Spark plugs.
    • Spark plug wires.
    • Ignition coils test for firing voltage with a test spark plug.
    • Crankshaft sensor.
    • Fuel injectors on multiport and sequential fuel injection systems. To remove the crank sensor
  • Disconnect the wiring harness.
  • Unbolt the sensor mounting bolt.
If the crankshaft timing sensor or the camshaft reference sensor is removed, follow this procedure when the sensor is replaced:
  • Thoroughly clean the sensor tip and install a new spacer on the sensor tip. New sensors should be supplied with the spacer installed.

  • Install the sensor until the spacer lightly touches the sensor ring, and tighten the sensor mounting bolt 105 in.lb.
hope this was what you needed.....
