Firstly was it working before. Did you take tank off for any other reason ie battery replace. Have you for any reason got the fuel connectors connected wrong way around.
Theres very little goes wrong under them unlike early models with rubber lines. Fuel sender and pump connected ok no bent pins I take it.
You say new filter etc and I dont want to assume but all correctly in the flow direction to pump etc. I diagnosed Tony's s4 the other day which turned out to be rotten pipes 15 yr old filter and a line off inside. Sounds like fuel starvation but I think it must be inside the tank not coming out of it.
