After changing pump and filter with still no start. I checked the relay. I bypassed the relay and the pump started pumping which told me it was the relay so I changed it out with a good one and it still did not work. Is there a second relay maybe or any help in this situation would be great, thank you in advance to all who help

Have you checked the socket for hot and ground to trigger relay?

Two of the connectors have power and two don't, I haven't checked the other two for ground yet.

You've checked all your fuses? I test each end for juice. Did you try and start car with bypassed relay?

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
