Hi,
The engine will run if it is one tooth off, maybe even two.
I'm looking at the manual for the timing belt replacement, and it shows that the camshaft and crankshaft pulleys both have a mark that is supposed to line up with a mark on the engine. There is also a mark on the flywheel that lines up with a mark on the transmission.
The next step is to line up the crankshaft pulley, or the flywheel with the appropriate marks on the block/transmission, and check the camshaft marks, they should be lined up, if not, adjust the belt timing.
Good Luck, let me know what you find out!
