So my Crank Position sensor went bad, had to remove timing belt to install new sensor and after re installing the timing belt I tried starting the car to test it out. The car ran for about 30 seconds before shutting off, I went to check the timing and realized the crank sprocket walked off the crank (I forgot to put the bolt on when testing it) so I lined the marks back up and set the timing belt again but now I cant get it started. ive checked all the marks a few times, tried using starter fluid to be sure it wasn't a fuel issue but cant get it to start. does anyone know what else I can try or test? Its cranking over fine, I hope it didn't cause any internal damage like bending a valve.

 

I would do a leak down test to make sure you didn't bend any valves.
