Im having with my R32 RB25det with at Wal bro GSS 341 fuel pump. The pump is running fine when i hook a 12v up to it but it wont run from the actual power plugs. tested power on all of the wires going into the fuel pump on the outside and inside and im only getting one reading and thats from the fuel sensor.no power or nothing. I have checked all the fuses and they are all fine.Im really unsure about this problem and really need it fixed cas i need to drive the car.

1. this is in the wrong section,

2. did you check it with the car running as i'm fairly sure the pump doesn't turn on till the motor gets cranked, is it wired the right way round

3. the walbros like more voltage than 12v, i ran a wire from the back of the alternator through a 20amp fuse to a 20amp relay which gets switched on by the factory wire, when i had the car dynoed with the pump on factory wiring it ran very lean till we figured out the pump wasn't getting enough power, i rewired it at straight to the rich side

1.what section should i put this into man? im not too familar with this site yet

2.yer i was driving the car and then it all of a sudden cut out and then diagnosed the problem to the fuel pump.pump wont switch on full stop with current wiring unless you hook it up to a 12v source.

3. is it hard to wire it that way?where is the relay that you run the wire through?

general maintenance, r32s have a poblem with the two speed pump control unit shiting itself, might be a place to start.

if you have no power at all at the plug you can't do what i did, you would have to run a wire from the cars factory fuse box to a relay and bypass pump control all together or replace the unit.

i ran a new wire from the alternator and installed a fuse and relay myself and only used the factory wire to switch the relay on so none of the power from the factory wire runs to the pump.

as for doing this its not that hard, i think from memory the whole job took about and hour, the worst bit was wiring the plug that plugs into the tank as the wire i used is a lot bigger than the factory one

This may seem real stupid but I found the problem and it was a fuse. The catch is the fuse was hiding behind my ECU. my fuel pump is powered directly directly there is 3 there actually.didnt even know that they would be there. Thanks for the help tho :)

    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
