Probably at the fuel cooler.

its an 05' ,i dont see any wires/sensor at cooler,im thinking its on the inj driver/module on the passenger side cyl head?

I'd think there has to be a probe of some sort directly immersed in the fuel stream somewhere and likely not under the hood in a higher area so more like below the filter.
Just guessing though.

The fuel pressure sensor mounted over on the drivers side is also the fuel temperature sensor. Is it throwing a code for it? Check the wiring first(espescially near the power steering pump where they are known to rub through and short out), and also check the bale plugs to make sure all the pins are in place and not pushed out. They do fail, but VERY rarely.
