Cannot get crank pulley off
I am trying to change the timing belt on my 1997 2.2L
Putting a MAC 1/2 drive Impact Wrench on the bolt it will not break.
What should I do?
I have heard that putting a breaker bar on it and using the starter can result in the end of the crank breaking off.
What should I do?
Thank you in advance.

Not sure what tool he's showing there, but try a couple things first.
Short impact socket without any extensions. You'll have to remove the plastic inner fender liner. Extensions will dramatically reduce the amount of torque actually delivered to the bolt. Even a deep socket will reduce the torque.
If you've already done that, the tool you want is called a Honda crankshaft holding tool (what a clever name). It's got a big (55mm?) hex-shaped lug that fits into the hex recess in the pulley. You hold that to work against your breaker bar & socket.
DO NOT use the starter motor. That works on a lot of cars, but Honda F-series engines spin the wrong way. You'll be tightening the bolt.

i just did the timing on my 95 i just put a screwdriver in the flywheel to stop it from turning and then used a breaker bar to break the crankshaft bolt loose i was able to jam it in there but u might need someone to hold the screwdriver for you

The picture looks familiar to me when I didn't have a compressed air or mo-jo impact wrench, except one thing. Or, may be two things. I had chassis on jack stands and used floor jack to support the extension/breaker bar assembly while the work is conducted.
Make sure to use a 1/2" breaker bar from a store where offers life time warranty.
Good luck with your car,,,

Yeah, good catch. I would NOT do that work with the car supported on a hydraulic jack. Blood makes such a mess on the underside of the car...
You'll be pulling pretty hard on that breaker bar, so support the car VERY solid. Then put a jack under the knuckle of the breaker bar, so you just get twisting force transmitted to the pulley-bolt.
