Need Help Gtr 4wd Problem

[monster930]

Hi all,

need some help or ideas.

i have a 95 r33 gtr that the 4wd system isnt working.

as soon as u start the car the 4wd light illuminates.

i have swapped attessa computer, g sensor all 4 abs sensors and we still only have 2wd.

i can hear the pumps at the rear pumping at start up, but we have a problem somewhere.

any ideas would be apreciated.

Thanks

might seem stupid, but you've checked for hydraulic leaks, the fuse, and bled the attessa system?

P.S: that pumping noise is probly fuel pump anyway, dunno how loud attessa pump is compared to fuel pump, especially at atsrt up

hi yep checked the obvious stuff, from my understanding the only things that can cause a issue are hydraulic pressure or an elec fault.

attessa is bled, 33 doesnt have a fuse like r32, no leaks.

the pumps prime as soon as u turn the ignition and they are very audilble on the gtr.

thanks anyway

hi,

the car is at the autoelec, i will have it back in a few days and i will count the flashes.

thanks for the reply

if you can tell us the number of flashes, there's a good chance we can tell you where the problem is.

... 33 doesnt have a fuse like r32, ...

Pretty certain they do, down by your right knee, just like a 32.

Fluid in the reservoir is at the right level (checked with IGN = ON)?

TPS connection is working?

33 is same as 34, it doesnt have a fuse you can pull to make it 2wd.
