2004 Hyundai Sonata No start and no crank

My daughter's 2004 Sonata will start sometimes, and sometimes it will not. It started this a couple of weeks ago. We took it to autozone and the error code that they gave us was the crankshaft position sensor. She took it to the shop; and the mechanic replaced the sensor and the timing belt for over $700. When she got the car back, it ran worse than before, and it was still not starting. Sometimes you could try it and it would turn right over two or three times, then it will all of the sudden do nothing.
She drove the car to the fair and when she was getting ready to leave the car crunk and cut off. It would not start back up, but it would turn over. I replaced the fuel pump and now I cannot get it to try to start. WHen I try to turn it over I can hear like a slight whistle sound like something is trying to happen, but it is not turning over at all.
Do you
have the same problem?

Check for spark. Pull a spark plug boot and stick a Phillips screwdriver with a good plastic or rubber handle into the boot than hold the blade near something metal on the car and crank it. Replace the boot/plug and repeat for each of the cylinders. Check to verify that the coil(s) is (are) getting power with the key on.

If the car has a distributor, pull the #1 plug and bump the engine over until the piston is as high as it will go. Bump it and stick the screwdriver in or, if you can, shine a light into the plug opening. Now pull the distributor cap and see where the rotor is pointing. See if it's within a couple/few degrees of the #1 plug wire location.

See if there's a shop or Autozone (Etc) near you that will either check ALL codes (hard AND soft) to see what the computer is thinking. But I wouldn't take it back to the same mechanic.
Was this
