One morning just wouldnt start.. add ether it will start and die on 2004 Oldsmobile Silhouette

replaced fuel pump didnt work no power to fuel pump..replaced crank shaft sensor, computer,checked fuses still nothing HELP

Replaced fuel pump relay? Should click twice, on then off, about 2 seconds apart if working, each time key is turned on or cycled to start then let off. Also possible broken ground supply wire to relay from ecm. if new relay don't help. Probably need hands on help from a mechanic. All we can do is guess at it!

I would agree with pushrod about the relay, did you check the power to the pump and ground.
How was the plug at the pump have seen lots burnt, if it was a after market pump was the wires connected to the pump its self
