You can try soaking the crankshaft bolt in PB Blaster. It is the best bolt loosener on the market. You can try a little heat to, but be careful as you may damage the main seal. Cranshaft pulleys can be near impossible to remove. You really need the holding tool which is a special tool from Pontiac or a Snap on rep.
A friend of mine had his 1" breaker bar with a fence post pole on it whhile he jumped on the pole before his crankshaft bolt broke loose. So don't feel alone. Also, try and see if you have a Harbor Freight tool store near you or look at the catalog online. You can literally get $500 tools for $50 or less. You could get a 1" electric impact wrench for probably $40 and it would have around 800 Ft. Lbs of torque. More than the Truck. So, be careful if you get one and you have to get the impact sockets to go with it and make sure it is correct fit. Harbor Freight is not a rip off and the tools are fine. They are just not made to be used constantly like a progfessional mechanich would even though I know plenty of mechanics that use them without a problem. It is an amazing store if you have one near you. It is worth a long drive.
So that might remove the bolt. Also, when you soak the bolt with PB Blaster, soak it and wipe it off and let it sit overnight as long as possible. The more nights the better. Really hose the bolt down with it including the backside of the crank pulley.
