Fpcm (Fuel Pump Control Module) Removal R32 Gtst

Hey guys,

I'm going thorugh the whole "removing wires that are needed" phase on my r32 gtst skyline and would just like to confirm more or less is that the FPCM unit and all it's wires (Green/white, White, Black, Black/Yellow) can be removed from the system, to me it makes sense that it can because a lot of guys out there are already bypassing it with the direct feed mod therefore making the FPCM and resistor in the engine bay useless.

I'll be re wiring the fuel pump setup tidily, so all the wires I really need from the factory setup consisting of fuel pump, fuel pump relay and FPCM is the following: (please note colour wires are for the R32 gtst.)

Black and Blue wire which comes off the fuel pump relay (Ignition)

Black and pink wire again off fuel pump relay (pin 18 off the ECU fuel pump trigger wire)

Yellow Blue at the fuel pump lid otherwise black/red on the loom side (fuel light wire)

Yellow at the fuel pump lid otherwise green/blue on the loom side (fuel level sensor)

I hope I am right, if anyone can confirm my workings that'd be awesome :-) have a great day and thanks in advance.

They are not 'bypassing' it, the fuel pump control module is energising the new power relay. If you bypass the fpcm your pump will never turn off, which is very dangerous in an accident.

Sorry, just going by the later VQ fpcm which actually controls the pump as stated in its name. I forget the ecu in the 32/33 is the only ecu in the car. Mine has 8.

Bypassing the resistor to remove weight seems pointless. It weighs less than 1 sardine.

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
