Alternator just replaced

"Does not sound normal" is not very helpful. That does not tell me what the symptom is. If I had to guess, based on the recent history, I would be looking at the new generator to see if it is locked up. It is more likely for a new part to fail than a bunch that have been working fine for a long time. Try spinning the engine by hand to see if it is possible. You can also watch the generator's pulley while a helper turns the ignition switch to "crank". If the belt is slipping over that pulley, the new generator must be replaced. The symptoms would include cranking too slowly, and possibly a squealing sound from the belt.

I still suspect the new generator is locked up. The way to verify that is to remove the drive belt, then try to crank the engine. If the engine starts and runs, you will not have power steering, and the battery will run dead within about half an hour, and less if the head lights and heater fan are on. With the belt off, you can spin the pulleys by hand to see if one is locked up.

Nope, the two are not related. You have to do a real lot of disassembly to get down to the timing belt.

One of my reference sources lists this engine as an "interference" engine, meaning a broken belt will cause bent valves. They recommend the belt replacement intervals to avoid that damage. It is also customary to replace the water pump and all the tensioning devices at the same time. Your mechanic will strongly recommend that if he has your best interest at heart. Some mechanics prefer to not replace everything in an attempt to save you a few bucks. I hope that isn't what happened here.

Well, at least they found it.
