Hello I am trying to replace the timing belt on.

Crankshaft pulley bolts are always tough on any car. I am surprised a 1" impact would not get it. Toyota, as many import companies do probably makes a crankshaft holding tool which you can most likely find aftermarket to save money. Just look up the tool on an internet search and see if you can get it that way. Advance Auto or Auto Zone may have one in their loaner tool program. I had a friend remove one on a Honda and he had to get a chain link fence post and stand on it to get the bolt to move. But, if he ahd broken it it would require a serious drill bit to repair.
Get some PB Blaster or WD40, PB is better, and soak it and wipe it of and soak it overnight as many times as possible. You want to be careful if you use any heat as you may damage the main seal. I have seen people place a wrench on the bolt and then the frame and use the starter motor to break it free, I would not reccomend it but I have tried it and it did not work for me. It all depends on if you can get the wrench wedged in on something where it won't move. It is also dangerous and could cause damage though. But I got desperate. I was working on an Eclipse and ended up cutting the lower lip off the timing belt cover off and slipping the belt in through the slot I had made and then I got some tubing and slit it down the middle length-wise and siliconed it in place of the area where I cut off the timing belt cover. I had tried for days to get the bolt off and had little choise. So, you are not alone and it is just tough. They are designed to not come off. They definately do that.

That sounds plausible. Sometimes you have to get creative with this bolt. Check enthusiast forums for your car as you will find information from other people who have done it as well.

I am glad to hear it worked out. Come back anytime you need help as you can see there are many helpful people here who have been in your situation before.
