Well drove home just fine went inside changed my clothes came back outside cranked her up an ran for probably 20 secs (letting car warm up.) an then died an noticed I couldn't hear my fuel pump priming anymore(walboro 255) . I jump out check my fuse pump fuse an its not blown then tried to jump the car off an nothing. Since then I have replaced the Fuel pump,Fuel filter, and relay. The ECU reads " all ok" an theres a full tank of gas. I'm getting a new battery tomorrow so hopefully that might help. If anyone has any ideas please suggest them.Thanks!

O an when fuel pump is wired to a 12v source the pump turns on an i'm able to start the car but bout 2 minutes later the exhast temp light turns on.

Do the GTS-T's have a fuel pump control module?

The GT-R's do, and they fail. The FPCM sets the voltage to the pump lower at idle, for less noise. See if you have one.

My R pump ran in high flow pretty much all the time in my T. bbbbbuuuuuuuuzzzzzzzz I know there is a power relay but I don't think it has that control module.

Fpcm is on top of the rear strut tower . Ballast resistor is by the areal . It's a earthing issue , hope this helps to those with the same prob. Real pig cos there's not much info about it . If any one can shed more light on which wires to bridge would be good .

Ok quick up date . There is more than the 1 fuse for the pump apart from the 1 in in the mother @$!,:? &!(:.? $!(?! )),,!!')&@$ing boot . There's 1 in the @&$(()!$'@(;:&$!?!?()$!!!! Fuse box on the drivers side knee panel . When you work on cars you always think the worst . So check your fuses 1st then hard wire pump . Then go FPCU . Raaaaah so happy but can't beleave I didn't check them .
