I have a 2000 Ponitac Montana van and lately when you go to put the van in reverse it won't back up, what could be the problem?

before u replace any parts u need to have the electronic engine control tested for trouble codes, this is the 1st thing that any shop does to know where to start the repair and diagnosis. Most likely u have a defective crankshaft position sensor, but have the test run..

SOURCE: Changing spark plugs in a 2000 Poitiac van.

There are a few ways to doing this, and it takes time and a few band aids. You can remove the alternator to give you some room to access the rear spark plug with an extension and swivel spark plug socket. You can also get to the plugs from under neath if you have a ramp and long arm, an extension and swivel spark plug socket will help. You may have to use a 2x4 to wedge the engine to give you some room if you have larger arms. The other way is to tilt the engine forward by disconnecting the two top engine mounts. First replace the 3 front plugs and wire one at a time so you don't cross them. After you have changed the front plugs have a friend help you. Make sure the parking brakes are on and disconnect the two top engine mounts, release the parking brakes and let the transmission in park. Push the van forward slowly to tilt the engine forward far enough to give you room with out pushing it to far in to the radiator. Put the parking brakes on again to keep the van from rolling back and place a block of wood behind and in front of the rear wheels. Don't want to lose an arm. Replace the rear plugs with extensions and a swivel spark plug socket. Note, your going to have to replace the spark plug wire since the rear ones are really hard to remove and pulling on then will destroy them, not worth the headache trying to save them. Use platinum plugs so you can get 100.000 miles before you have to change them again so use anti-seize on the plugs so you can remove them again. Good luck and hope this helps, I personally go from under the van.
