I have the same issue, my fuel pump is bad, sounds like rocks in a box when it runs. I have powered the pump and you have to tap/bump it to make it run. at the same time I have no ground to my fuel pump relay. I can ground the relay out and get power to the pump (ground turns the realy on) but it still is a no-start. I now have fuel pressure (when the pump runs) but no start (plugs do show spark). if the dme is bad could this also prevent the injectors from firing?
