Crankshaft pulley bolt
 

Hello everyone.
I'm working on my nephew's '92 ES300 and have hit a wall. I'm doing a timing belt job and the crankshaft pulley bolt will NOT come off. I've done many jobs like this on other vehicles and the trusty electric impact has always worked but not on this car. I even rented a beefier impact to no avail. I even tried the opposite direction in case of left-handed thread. Nuttin. I know little about Lexi so is this common? Next step is to apply heat and try again. Any suggestions or imput? Thanks in advance.

ive never seen one that just wont come out...perhaps someone else had it out and cross threaded it? that would make for a dreadful job.
