Hi guys, I'm hoping someone here can help me out with what seems to be a bit of an unusual problem. :P

I have a R33 GTR VSpec. When I turn the car on (start engine) the 4WD pump whines and works like it should? But after about 2-4 minutes (variable) the 4WD and A-LSD lights come on and the ECU in the boot flashes codes 53 "Pressure switch and circuit". These lights come on as soon as the pump stops. But if I start to drive the car before these lights come on (i.e. almost immediately after starting it up), the lights remain off and the pump works continuously during the journey. It only seems to stop on idle or when stationary for about 2-4minutes.

The fluid was low but I have topped it up (not bled it).

Has anyone else ever had this problem? Any suggestions on what this might be?

Any help much appreciated!!!

Ok suffering the same situation atm, but with a R32 GTR the 4wd light seems to like being on and now it is doing it more frequently what is this as my ecu has been put on a diag computer and isnt flashing any signals?

Ok so after a bit of searching and bleeding the system, the torque gauge is still slow to react to front torque and the 4wd light comes on after 1min of start up if not straight away....? Need help!!!!!

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
