What I sent is thfor the proper year car you asked for. If it's different then it's the wrong year posted and the blue wires will be either light or dark blue or possibly green which all of those colors are posted in the diagram I sent.

Ok what I have is fuel pump that dodnot come with the fuel sensor so I put the old one on the pump which was working when I took it off but after I put it on the new pump the fuel gauge didnot work then I brought and new sensor still the gauge dont work. I just forgot to look at where the wire went.I have three holes and two wires. I have them side by side now still nothing.

The diagram I sent is correct for that model year. Are you sure it's a 2005? If the pump didn't com eon tha tis completely different from wha tyou first described. Have you check yoru relay an dfuse under hood? Your oil pressure switch and is the pcm tellin g the relay to workk? Check all that first before you just decide it' a fuel pump problem then take everything apart and don't know how to put it back togehter

You need a pro model scan tool to fix this. The voltage is high going to the fuel sender and the scan toold needs to do some stuff you can't to fix it.
