I have a 2010 traverse ls. This is how I got the car so don't know it's history and since the battery had been out no codes.

It will crank but no start, can't hear pump priming and no pressure at rail. I jumped the connectors at the fuel pump module in back of the car and could hear the pump running and it seemed to sound normal. Tried to start it while doing this and still no start.

Why ideas what to check next?

There are 2 fuel pumps. High pressure fuel pump is up by the engine. Fuel pump failure?

Shouldn't the one in back still prime?

There is a plug under the car by drivers seat area. Sometimes that comes loose and does stuff with fuel pump and engine operation.

Plug and connections looked good. Is it just one plug or 3? Looks like room for 3 but I don't see any metal connections in the other 2 nor any loose or hanging plugs that could fit in there

So how do you know there is no pressure at the rail? If you open those connections on the High Pressure side, you are supposed to replace the piping. Get a Bluetooth Scanner so you can read vitals.
