07 Camry will not start

I have been having some issues with my 2007 Toyota
Camry. I recently replaced the radiator, and also have a
slow oil leak.  The car shut off while my wife was driving it
so I had it towed to a mechanic. The next day when the
mechanic tried to start it, it cranked right up  and he told
me it was running fine and they did a compression test
and this was also fine. So I picked up the car, drove a mile
down the road to a gas station  and stop there because it
was running rough. I check the oil it was extremely low,
and there was no coolant. I put in 3 quarts of oil and half a
gallon of coolant  and started on my way home. After
about another mile and again to heat up and once I got
home the temperature gage was in the red. I found a leak
in the coolant which is probably why it was  empty to
begin with. It was only a loose hose so I fix that myself but
now it will not crank at all. Any help would be greatly
appreciated
