Timing Belt

It started when I accelerate, engine goes off.I complained to my mechanic and I was told its fuel pump problem, later the display screen on the dashboard showed "risk of ice" but I ignored it since I live in a tropical country in west Africa. Days later, I heard rattling sound and my timing belt snapped.I ve since replaced the timing belt and all bent valves also serviced the fuel pump but the car wont start. Does the ice have anything to do with these problems or is it something else. Please help.
