I have a 2000 honda accord lx 2.3 liter vtec how do you get off the crankshaft pully tried impact wrench wont buch.

 

There are some decent videos on YouTube is you search accord crank pulley bolt.

You will need the special holder. I used the jackstand to support the end of the extension.

I did this with the spare tire on the driver's side, so I couldn't pull the car off of a jackstand.

Another option is to take the car to a shop and have them use their more powerful impact to break the bolt loose, then tighten it back down.
