If the timing belt breaks, it will cause major internal damage to this vehicle. This is what is referred to as an interference engine. Basically, there isn't enough room between the top of the pistons and the valves when they open. So, if the timing is off while running as a result of the belt breaking, they will hit.
Now, do you have the vehicle? If the belt hasn't broken, we need to check for spark and fuel to the engine. See if the engine will start with starting fluid. If it does and then stalls, we know it is fuel related. If there is no change, suspect an ignition issue. Here is a link that explains how to test for ignition spark to the plugs. Do this and let me know what is found.
Next, if you could record the engine cranking and upload it for me to hear, I usually can tell if the timing belt has broken or if the timing is an issue.
As far as the water pump goes, in and of itself, it won't prevent the engine from starting. Also, it's a bit hard to believe that all the coils failed at the same time as well. So, let me know as much as you can. For example, were there symptoms prior to failure? Was the engine overheating? Were there any strange sounds from the engine?
Let me know.
