If your car isn't starting at all, and you hear the fuel pump prime that is usually a good indication that the pump is working to some chapters.  Testing your Civic's fuel pressure on each side of the pump would exist the all-time way to diagnose this problem.

A priming fuel pump sounds similar a high-pitched whine for a few seconds and can be heard with a abrupt engine right after the ignition key is turned, but before the starter is engaged.
