    Thank you. I was able to use a long flat head screwdriver from under the car and popping the sensor out in one piece. Thankyou for the advise

  • Eric Semrow Dec 02, 2012

    Now the car starts, but i runs awful. I cant get it about 2500 rpms. I verified spark on all six cylinders. As well as replaced the 7x sensor. My next step is to check fuel flow, however, once it ran it was rather rough and kicks a p0300 only. Any advise?

Keep twisting and gently prying out on it. They are known for being stuck in the block. It is very common for them to brake off in the block. If that happens you will need to pull the oil pan to remove the broken part. I have on many occasions had to purposely brake them and then carefully drill into the broken part enough to get a screw threaded into it and then pull them out by the screw.

SOURCE: key stuck

Under the steering colume the should be a small hole or a small cover that you can take out to reveal a small hole that you can reach up into and push on a silver cylinder type thing pulling it back towards you and that should release the key.

You need a three jaw puller to remove the balancer. After you remove the center bolt the puller hooks into the three holes in the balancer.

How to change crankshaft sensor on 1999 grand price gt

To get to the sensor, the harmonic balancer pulley on the crankshaft has to be removed. The center bolt on the harmonic balancer is on very tight. To loosen without an impact wrench, remove starter motor and wedge a piece of wood against the flywheel, or use a pry bar and hold the ring gear on the flywheel rigid, while loosening the crank bolt. The engine will try to turn backward when you loosen the crank bolt, so you have to hold the flywheel rigid. Once the bolt is removed, see if you can get the harmonic balancer pulley off without a gear puller. Just try tapping it to see if it slides off, or use two screwdrivers on each side behind the pulley and see if you can start it sliding off. If it is on very tight, as many are, you will have to get hold of a harmonic balancer removal tool-a simple, inexpensive puller that bolts onto pulley and can be drawn off. You might be able to rent the tool too.
BTW, you will need to have the wheel removed from passenger side, and the inner fender cover removed to get to the crankshaft. Once the pulley is off you can unbolt the sensor and put the new one on. GM recommends using a sensor alignment tool to install, because the thin vanes on the back of the harmonic balancer pass through the sensor, and if not aligned right could damage one or the other. If you don't have the tool, put the sensor on loosely mounted, just snugged up finger tight, then test the pulley will slide through the sensor slots without touching either side of sensor. If it looks right, tighten down the sensor in place, install the harmonic balancer pulley and tighten the center crank bolt to about 105 foot pounds.
Wedge the flywheel again so the engine won't turn when tightening the crankshaft bolt.
Good luck, and hope you get it.

Were is the crankshaft sensor located at on 96 neon

  • It is located on the firewall side of the engine block, passenger side, under the power steering pump. Unplug the electrical connector on the crankshaft sensor by lifting the plastic lock tab and pulling it off.
  • 2Remove the 10 mm bolt that secures the sensor to the block, using a socket. The bolt is in the hold down bracket. Twist the sensor to ease removal.
  • 3Insert the new sensor after checking to make sure that the O-ring is installed to prevent oil leaks and the spacer that comes with the sensor did not fall off. Insert the sensor and give it a little twisting motion as it is installed. Align the hole in the hold down bracket and insert the 10 mm bolt and tighten with a socket. Plug in the electrical connector.

    How to put on a crank sensor for a 2.4 engine of a 2001 oldsmobile alero?

    The crankshaft position sensor on your vehicle goes through the engine block and is held by a single mounting bolt.
    Disconnect the electrical connector.
    Remove the mounting bolt securing the sensor to the engine block.
    Using a "twisting back and forth" motion, remove the sensor from the engine block.
    NOTE: it is common for these to be coated with carbon deposits that may cause them to stick and make them difficult to remove. Be careful to pull STRAIGHT out and use the twisting motion mentioned above, to avoid breaking the sensor off inside the engine block.
    The crankshaft position sensor is located on the left side of the engine block near the oil filter.

    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.

    1994 olds 98 rear seat belt (behind driver seat) is stuck

    If brute force doesn't unstick it remove the back seat and pull the cover off of the reel. The problem should be apparent. You can turn the reel with a large screwdriver if need be.
    If the belt is damaged find another one at your local recycler, the side reel is behind a plastic panel that is easily removed, the assemblies are held in by big bolts.

    How do you replace a crankshaft sensor for a 1997 olds Delta 88?

    There are two crankshaft sensors located at the edge of the harmonic balancer. That's the large wheel coming out of the engine, passenger side, the wheel that powers the serpentine belt. One sensor is the crankshaft position sensor and the other is... I forget... crankshaft angle sensor or something. I replaced both on my car. I don't know wich one is your problem. When you buy a sensor, get the one with the mounting bracket already attached. They had problems with the sensor getting damaged from being adjusted wrong. Having the bracket already attached gives you the right adjustment.

    Remove the serpentine belt. (It has a tensioner wheel. When that is moved, the belt becomes loose and can be removed.) With an 18 mm wrench, turn the crankshaft until one of the openings in the metal fin is at the sensor, giving a space where the sensor can be removed. One sensor is reachable from the top, but it is real hard to see. The other is reachable from underneath. My guess is, the lower one is you problem only because my lower one failed twice and the upper one only once. Your son has to crawl underneath, unhook the wire from the sensor, and unbolt the sensor mounting bracket. Put the new one in. Keep your fingers crossed.
