The fact that you have no fuel at the rail would indicate to me an issue with the fuel pump or the electrical circuit that runs it including the fuse or relay. If you did not hear any noise when you turn the key on, then the fuel pump is not priming. Then the question becomes why.

Normally I would agree with you that no spark plus no fuel at the injectors points to CKP. However if there is no fuel at the rail, there is something not right before you can lay blame on the ckp.

The fact that your gas gauge is wonky May point at an electrical issue at the connections to the fuel pump. If the sending unit and the fuel pump are on the same circuit, you may have lost a ground which is keeping the fuel pump from running and also messing up the voltage signal sent by the sending unit as the ground side of that circuit may be floating.

Does your dome light work inside the car? Serious question.
