I wouldn't have gone to the fuel pump without a fuel pressure test. The first issue you described, 'It would crank twice and the starter would spin and run but not engage the fly wheel.' is a starter bendix failure. A brand new starter and now it won't click even? What is the status of your battery? Are you sure the starter is good? You can test it yourself. Take it out, hook your jumper cable up, positive to the terminal, and when you touch the case where it bolts on with the ground, it should spin, AND kick the gear out as if to engage the flywheel. Be warned it will twist, so hold it.

I think you will be better served by following some diagnostics before tossing parts at it.
