I have used the three prong pulley puller, beat on it with a hammer used the pulley puller again and had it cranked so tight that I almost could not get it loosened back up. The bolts are out of it, nothing's holding it. Please I spent 5 hours on that o e pulley today and I just need your ideas, help cause I jus don't know what to do. 89 Chevy Astro mini van with a 4.3 vortex motor. Thank you very much...

awesome trick! (as long as the engine cranks the right way)
GM uses a J 23523-F tool. It bolts right to the holes in the balancer. Maybe you can loan this tool from somewhere like Autozone.
other than than , just douse it with penetrating lubricant and let it soak in. Use heat if you have to.
