A failed timing chain most likely has caused damage to the engine valves at the very least. it's possible to do a great deal of damage to an engine when the chain fails. I don't see how it would cause coolant to get in the fuel but it's possible to break enough parts to allow coolant to get in the oil. If you have coolant in the oil that's very bad news. I suggest considering getting a guaranteed used engine for your car, it's possible the engine isn't salvagable or the cost of repairing it is greater than the car's value.
