MF 65 Engine won't crank unless injector removed

[pmsmechanic]

How do you know there is no water in the oil? Did you physically loosen the drain plug and make sure there is no water? Just looking at the dip stick and checking the oil doesn't indicate water in the oil until the engine has run and mixed the water and the oil turning the oil grey.

could be weak battery. do light dim when cranking? if so it could be battery. have it checked or if old enough just replace.
