Bought some biodiesel that was apparantly filled with water. Car having hard time starting and injector pump making lots of racket going down road. Can this be rebuilt- where to buy new ones? How to know for sure noise is coming from injector pump?

Dump the bio thats in there, dont keep burning it, get yourself a clean HDPE bottle, and pour some diesel in it, disconnect your incoming line, and put the hose in the bottle, start the car and see if the noise continues, if it doesn't, run diesel for a while, water will definately destroy your injectors

Ditto. Drain and properly dispose of everything in your fuel tank, purge the lines and pump of any fuel they may contain and fill the tank with fresh D2 from a clean source.

Any amount of water in the system is very bad. Do not drive it any more until you have drained the tank and get new fuel in there.
