code was for a crankshaft pos sensor being bad. replaced, still no change. Next?

First off just because you have a code for a crank sensor doesn't mean the crank sensor is bad. Every code has a list of test that need to be performed by a technician to determine the root cause of the issue. Pulling the code is the easy part, it's the diagnostic work that takes skill and knowledge. Reading your post, I would recommend you go back and double check the timing belt is installed correctly. If everything looks good, you might want to tow the vehicle to a professional technician and have him look at it before you waste anymore time and aggravation.
