Hi,
The sensor is located to the right of the crankshaft behind the vibration dampner (harmonic balancer). You will need a balancer puller and a special tool to space the new sensor correctly.
(can be done also with eye spacing, but the tool is recommended to ensure proper spacing as to prevent damage to new sensor and / or harmonic balancer.) You will also need a strap wrench to hold balancer pulley in place while removing and re-installing balancer to crankshaft bolt. (helper required)

Procedure for replacement:
Remove negative battery cable.
Set parking (emergency) brake.
Release tension on serpentine drive belt and remove belt from harmonic balancer pulley. ( large pulley at bottom of engine)
Break loose lug nuts on passenger side front tire, do not remove bolts yet.
Raise and support vehicle on passenger side, remove wheel.
Remove plastic splash guard (cover) from passenger side wheel well.
Remove dampner / balancer center retaining bolt (counterclockwise, it is torqued very tight.) Use a strap wrench around pulley and have a helper hold that in place while using a 1/2" breaker bar and socket to turn pulley bolt out of crankshaft. Be careful not to rotate engine in a counterclockwise direction while breaking the bolt loose.
Using balancer puller, remove dampner / balancer pulley from engine.
You will now see the crank sensor to the right of the crankshaft bolted to the timing cover.
Disconnect sensor wiring and remove retaining bolts, remove sensor.
Put new sensor in place and screw in bolts, do not tighten them yet.
Reconnect wiring to sensor.
Now use special tool to properly space sensor. If you cannot find one at the parts store, you can space the sensor with the balancer pully held in place (not installed yet) and space the sensor evenly with the veins on the hub of the balancer pulley. Take your time and be sure it is as evenly spaced as possible.
Tighten sensor bolts.
Clean balancer hub free of any oil and dirt deposits using brake or carbeurator cleaner.
Reinstall balancer to crankshaft by tapping around the inner surface of pulley with a rubber hammer.
It is a press fit, so be sure you have it started evenly and progress slowly in a circular motion to ensure you are keeping it aligned straight with the crankshaft.
Reinstall balancer bolt using the same method as removal, torque bolt to 110 foot pounds, then tap around balancer again twice with rubber hammer, turn the engine 2 full revolutions clockwise using the balancer to crankshaft bolt, then tighten bolt an additional 1/4 turn.
Replace splash guard, put wheel on tightening lugs to finger tight and then wrench tight in a star pattern.
Lower vehicle until wheel makes contact with floor, tighten lug nuts to 115 foot pounds in a star pattern using a torque wrench.
Fully lower vehicle, remove jack.
Re-install serpentine drive belt
Re-connect negative battery cable.

End of procedure....Hope that helps!.....Mike

check for spark and fuel after it dies.

If there is spark but no fuel, then the fuel pump may be bad or a clogged fuel filter.

If there is fuel but not spark, then the ignition control module or the ignition coil could be bad.

Also, check that the timing belt is timing the engine correctly.

hi, here is a guide i have come across on this site written by another expert it should be the one for your engine but always double check.

If you are unsure what you are doing then please go out and buy a haines workshop manual as these tell you every detail you need to know so that would be your best solution.

Please dont do this work if your unsure what you are doing as you could damage the engine beyond repair so you have been warned;

it covers single cam and if you scroll down it shows double cam ok

1. Note the radio security code and disconnect the negative battery cable.
2. Place the (hood) lock carrier in the service position. For additional information, please refer to the following topic(s): Body And Trim, Service Position, Front Bumper, Hood Lock Carrier.
3. Remove the engine accessory drive belt. For additional information, please refer to the following topic(s): General Information And Maintenance, Routing Maintenance And Tune-up.
4. Turn the engine by hand to Top Dead Center (TDC) on the firing stroke for cylinder No. 1.

NOTE The large holes in the camshaft sprocket lock plates should be on the inside facing one another.

1. Remove the Crankshaft Position (CKP) sensor from the lower left side of the engine block. Make sure the engine is at TDC and install the threaded crankshaft holding pin Tool No. 3242 and lightly tighten.
2. Remove the upper timing belt covers, the crankshaft vibration damper and then the lower timing belt cover.
3. Loosen the camshaft sprocket bolts slightly and use a suitable pulley to release the sprockets from the tapered ends of the camshafts.
4. Loosen the tensioner roller and remove the drive belt.

To install :

1. Install the timing belt over the sprockets, then the idler rollers and lastly over the tensioner.
2. Install camshaft alignment tool holder Tool No. 3243 into the camshaft alignment flanges.
3. Check and adjust the cam belt tension such that the upper left portion of the belt between the tensioner and the left cam gear can just be twisted 90° ( 1 / 4 turn).
4. Tighten the cam belt tensioning roller to 33 ft. lbs. (45 Nm), and the camshaft sprocket bolts.
5. The balance of the installation is in reverse order of removal.

First remove right front tire and support vehicle with a jack stand. Remove splash guard lower portion near the harmonic balancer. Remove all drive belts. First remove the A/C alternator belt. Loosen the 14mm bolt at the front of the belt tenioner and then loosen the tensioner bolt (it is the one that stands out, you use a socket on it.). The power steering adjuster bolt with be gained from the bottom. It has a 12mm bolt head on it. You will break the jamb bolt loose first and then loosen the adjusting bolt. Pull down on the belt the help move it after you've loosened it some.Then remove harmonic balancer bolt (19mm).If the harmonic balancer will not slide off the crankshaft then use a two finger gear puller. Place the harmonic balancer bolt back in the crankshaft but do not tighten it. Leave it about a half inch from being all the way in. Next place the puller onto the harmonic balancer (one finger on each side securely press into the belt groove. The center puller bolt will rest against the harmonic balancer bolt head. Tighten the puller bolt and make sure the harmonice balancer bolt does not turn. The balancer should come off at this point.

Okay, on your engine, the alternator is mounted below the rear cylinder bank of the engine, at the rear of the engine compartment. It'll be easier to access it from the driver's side front fenderwell (take off the right front tire then the plastic lining) or under the car. You might want to go ahead and remove both the liner and work from underneath as you'll need to remove your crankshaft pulley.

1: Disconnect the negative batery cable.

2: Disconnect the electrical connections from the alternator. The output wire is secured by a nut on the output terminal.

3: Revove the serpentine/drive belt.

4: Remove two bolts and one stud bolt that secure the alternator to it's bracket. Remove the crankshaft pulley.

Installation is reverse of removal.

After installing the alternator, reinstall the drivebelt and reconnect the negative battery cable.

To remove the crank-shaft pulley

1: As you'll aready have the wheel, liner, negative battery cable, and serpentine/drivebelt removed, as well as the car on jackstands, I'll omit those steps.

2: Remove the driveplate access cover and hold the ring gear teeth with a large scredriver or pry bar to prevent the crankshaft from turning.

3: Remove the nuts that secure the pullley bracket to the engine front cover. Remove the pulley and bracket.

4: The crankshaft pulley screws into the harmonic balancer with a left hand thread (reverse threaded so rightly loosey lefty tighty). Trun the crankshaft pulley clockwise to loosen and remove it.

5: Hopefully this is where you'll end with the pulley. The harmonic balancer is no fun to remove, but let me know if you need to know this too. After you have your alternator installed, put the pulley back onto the harmonic balancer before installing the serpentine/ drive belt.

Hope this info helps.
