Fuel pump relay sound bad. Under the hood in the fuse box is the location of the relay. Look under the cover for the diagram to locate it faster. Hope this helps. Please keep me posted. Good luck

Per your description, it sounds like you are missing an injector pulse from the ECM.
Check the under-hood fuse box and verify the "ECM1" fuse is good (12 volt supply to injectors).
With the key in the run position, verify you have 12 volts at an injector.
Barrow or purchase a "noid" light to verify you have an injector ground pulse from the ECM.
Let me know what you find and we can proceed from there.
Regards,

Have you checked that engine oil level is okay, if so check that oil pressure switch is good. The switch is usually bypassed to start the engine, but it won't run with no oil pressure indicated...hope this helps

Using a multimeter check the wiring for power at the pump and at the relay. It sounds like a bad relay.
