Cranks but won't start.. Could it be the water pump

What is your question?

I was driving my car on Thursday and early Friday morning, and I went to start it later Friday morning it wouldn't turn over. My timing belt replacement indicator light is on. Serpentine belt has been replaced. Plugs and wires are good and so is battery. Gets power from alternator. Grinds and squeaks sounds like metal and rubber grinding together
