1993 Dodge Colt won't start

Engine Mechanical problem
1993 Dodge Colt Front Wheel Drive Automatic 120000 miles

i try changing the starter, check the fuses, wires. i just don't know what it can be. need help. last i drove it, was on a rainy day. i drove a road pretty fast and water must the splash in under the engine. since then it won't start. when i turn the key it seem like the starter is dead. but i try that already. need help.
