Why do my crankshaft doesn't run when attached to the engine

If you're looking for the seal -have a look on Ebay:
1 042results for equinox crankshaft seal

If your question relates to a leak, a classic symptom of a leaking crankshaft seal is drips of oil from the bell housing - where the transmission attaches to the engine. It only leaks when the engine is running.

To replace the seal you need to remove the transmission/clutch/flywheel assembly -or in the case of auto transmission - the torque converter which attaches to the rear of the engine.

To remove the old seal you simply prise it out with a screwdriver, lubricate the new seal and gently tap it into position. However as mentioned, you need to remove the transmission first..

Look on the link below. There's a few images which will help you locate that sensor:

location of 1995 ford probe crankshaft sensor Google Search


The sensor will be located located where the engine attaches to the transmission. Have a look around where the engine attaches to the transmission .. top, sides and underneath. The crankshaft sensor will have a minimum of 1 wire attached.

You'll locate it easily

If the car is running then the crahkshaft HAS to be spinning. That's the big one that turns every other pulley on the engine. Perhaps you're looking at a different pulley??

Hi,
REMOVAL
Disconnect the negative battery cable.
Remove accessory drive belt.
Remove the timing belt cover.
Align the timing mark on the camshaft sprocket with the timing mark on the cylinder head.
Confirm that the timing mark on the crankshaft sprocket is aligned with the timing mark on the oil pump housing.
Loosen the belt tensioner attaching bolt.
Pry the tensioner away from the timing belt and tighten the attaching bolt.
Remove the spark plugs.
Remove the RH engine mount and raise the vehicle.
Remove the splash shield.
Remove the crankshaft damper.
Remove the timing belt.





INSTALLATION


Note: Do not mix 1/2 round and trapazoidal belt tooth profiles. This can cause premature belt wear, also the belt is meant to run in a dry environment. For maximum belt life, no oil or belt dressing compound should be applied to the timing belt.
Install the timing belt over the sprockets in a counterclockwise direction starting at the crankshaft. Keep the belt span from the crankshaft to the camshaft tight while installing over the remaining sprocket.
Loosen the belt tensioner attaching bolt, allowing the tensioner to snap against the belt.
CAUTION: Do not rotate crankshaft with the spark plugs installed .


Note: Do not turn the engine counterclockwise to line up the timing marks. After rotation, recheck camshaft timing marks for alignment. This will verify that the belt has not skipped a tooth during rotation.
Rotate the crankshaft clockwise two complete revolutions (720 degrees) stopping at top dead center. This will allow the tensioner spring to load the timing belt.
Tighten the belt tensioner attaching bolt to 23-30 Nm (17-22 lb-ft) .
Install the crankshaft damper.
Install the splash shield.
Lower the vehicle.
Install the RH engine mount.
Install the spark plugs.
Install the timing belt cover.
Install the accessory drive belt automatic tensioner.
Install the accessory drive belt.
Connect the negative battery cable.


Thank you.

Attach the arms of the crankshaft pulley removal tool over the pulley and tighten the tool to the pulley using the tool's supplied bolts. Continue to tighten the tool using the bolts until the crankshaft pulley is pulled off the crankshaft. auto zone rents out tools for the job.

Your crankshaft is located inside the engine, running parallel to the oil pan side rails, centered between them. The back end of the crank is bolted to the flex plate or flywheel (depends on if it's stickshift or automatic). The front or "nose" of the crank protrudes into the harmonic balancer (the lowest pulley on the front of the engine...the one that turns when you engage the starter even when all the belts are removed).
All of your pistons are connected to the crankshaft via the connecting rods. The crank attaches to the camshaft via a chain or belt inside the front of the engine. This arrangement is the same regardless of what make, model or brand of engine though the crank design specifications may vary (engine displacement is partly governed by specifications of the crank
(called stroke....two identical engines with different strokes will have different displacements).

Check for spark. My guess would be the ignition module going out, but could also be the crank sensor. The module sits under the coils. Check all coils for spark. If any coil doesn't spark, you can try replacing just that coil, but the problem may still be the module underneath. If you have a meter, run a resistance check on each coil from the terminals to ground. If the same coil that doesn't fire aslo has a different resistance, replace that coil.
If you have a meter, check the AC voltage on each of the crank sensor wires shown as compared to ground or battery positive. If the AC voltages are different on the three wires, suspect the sensor is bad, but also check the tone ring on the pulley (Fig 2 below) for any damage.
Please see my tip at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines for how to check for spark. These are genericinstructions.
The 3.3L engine is the only one with the C 3 I system. REMOVAL and INSTALLATION C3I Module See Figure 1

Dual Crankshaft Sensor
See Figures 2, 3 and 4

1. Disconnect battery negative cable.
2. Remove serpentine belt from crankshaft pulley.
3. Raise and safely support the vehicle.
4. Remove right front tire and wheel assembly, then the inner access cover.
5. Remove crankshaft harmonic balancer retaining bolt and crankshaft harmonic balancer.

Fig. Fig. 2: Harmonic balancer with interrupter rings on C 3 I system

1. Unplug the electrical connector from the sensor and remove the crankshaft sensor from the vehicle.

To install:

1. Loosely install the crankshaft sensor on the pedestal.

Fig. Fig. 3: Dual crankshaft sensor - C 3 I system

1. Position the sensor with the pedestal attached on special tool J-37089.
2. Position the tool on the crankshaft.
3. Install the bolts to hold the pedestal to the block face. Tighten to 14-28 ft. lbs. (20-40 Nm).
4. Tighten the pedestal pinch bolt to 30-35 inch lbs. (3-4 Nm).
5. Remove special tool J-37089.

A clearance of 0.025 inch is required on either side of the interrupter ring. Be certain to obtain the correct clearance. Failure to do so will damage the sensor. A misadjusted sensor of bent interrupter ring could cause rubbing of the sensor, resulting in potential driveability problems, such as rough idle, poor performance, or a no start condition.

The crankshaft is the main shaft that all the pistons are connected to by connecting rods. It is an internal part with both ends sticking out. In the front, the crankshaft pulley is bolted to it and it rotates when the engine is running, making the belt run around the pulleys for your power steering, and alternator to charge the battery. At the back is where the flywheel is attached. Your starter engages this to start the whole thing in motion. Your transmission is attached to the flywheel by a "torque convertor". the convertor converts the spinning motion of the engine(crankshaft) into usable power through the gears to make your wheels spin and down the road you go!

The crank sensor is located on the engine near the flywheel axis of the crankshaft.

Crankshaft Position Sensor Removal & Installation To Remove:
Location of the crankshaft position sensor on the 2.4L engine
Location of the crankshaft position sensor on the 3.0L engine
Location of the crankshaft position sensor on the 3.3L and 3.8L engines
NOTE: On the 2.4L engine, the crankshaft position sensor is mounted to the engine block behind the alternator, just above the oil filter. On the 3.0L, 3.3L and 3.8L engines, the crankshaft position sensor is mounted on the transaxle housing, above the vehicle speed sensor.

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Disconnect the crankshaft position sensor electrical connector.
4. Unfasten the sensor mounting screw, then remove the sensor from the vehicle by pulling it straight out.

To Install:
NOTE: If the sensor removed is going to be re-installed, clean off the old spacer on the sensor face. A new spacer must be attached to the sensor face before installation. If the sensor is being replaced, be sure that a paper spacer is attached to the sensor face.

1. Install sensor and push the sensor in until contact is made. While holding the sensor in this position, install and tighten the mounting bolt to 105 in. lbs. (12 Nm).
2. Connect the crankshaft position sensor electrical connector.
3. Lower the vehicle.
4. Connect the negative battery cable.
