No need for the caps man... Have you tested your fuel pressure? It really is the only way to diagnose a failing or faulty fuel pump. The fact that you can hear it doesn't mean that it is supplying the flow and pressure required for proper operation.

Sounds more like a bad ignition switch module.

RE: PUMP RUNS NO START

I concur with Kyle, sounds like a faulty fuel pump. Nascar28 states the vehicle turns over so the ignition seems to be working OK. Check the fuel pressure with key on/no start, you need 60 psi for starting. Watch the guage and see if the pressure bleeds off quickly, could be a leaking injector, a bad fuel pressure regulator, etc.....
