Won't crank. My montero sport had a water leak but I kept water in it and it never ran hot. One day I washed it at a car wash and drove maybe 15 yards and it died and now it won't crank. Any ideas

 

Does starter engage (clicks) but can't turn the engine over? Can you turn the crankshaft by hand? Perhaps, somehow you got it hydrolocked (water got into intake or something like that). If you can't turn it over by hand, take out spark plugs and try again to turn over the engine. See if any water comes out of cylinders. If you can't turn it without spark plugs in it - something went massively wrong internally.
