Whats This Relay?

[TJHill]

Ok so after finding a problem in my new stagea I have found a relay that sounds rather upset and after some snooping around online I can't manage to find what it is or where it goes so hopefully someone here should be able to help. I don't know if all models have it but I have a '97 series 1 model.

Now this relay is on the drivers side, mounted to side of engine bay behind strut tower and to the drivers side of brake master cylinder, right up in the drivers side back corner. It's a black relay and has from what I can see, 2 plugs that attach to the bottom of it.

I hope this gives you a fair enough idea of what it is and where it is

No idea what that relay does. Does it look factory or has it been added? What is going wrong with your car?

4wd pump relay, if its clicking annoyingly either means your 4wd accumulator or attesa pump needs replacing.

To fix, firstly try a new accumulator, usually good for 10 years, 350+ from nissan. Pm me as i have a near new (july 12) spare one for sale. Fitted for a few weeks only. Didnt fix my issue, as i ended up replacing pump and fitting my 2 yr old accumulator.

Thankyou! Yea it does have that annoying tick.

Other problem I have iss aftermarket fuel pump that isn't giving me enough output when I lay my foot down. Which I have been told a bosch 040 will fix. Does the old stall around right handers anywhere under 1/2 a tank if I take corner too quick but shocking under 1/4 of a tank.

The aftermarket fuel pump probably is an 040.

No I have receipts from previous owner. It's some tuffcarparts.com.au stealth fuel pump.

Awesome news, now i know what that Fking clicking is

2ndly

how hard is it to replace the pump... and what do you need to do...

Get an accumulator from nissan, jack or hoist car up, locate pump above rear diff, unscrew old accumulator...slowly to relaese pressure, will be messy with some fluid. Can be hard to remove, no space for pipe wrench. I used a chisel n hammer to loosen the accumulator. Install new one, grease o-ring first. Manual says to hand tighten, then tighten with tools so it moves 5mm on outside.

Fill up the fluid reservoir in boot to the brim, well above max. Activate the attessa pump manually by disconnecting the black plug behind the drivers kick panel. Turn key to ign, u should hear pump running. You then need to bleed fluid, 2 nipples, one at back of transfer case and one on pump, exhaust side. Run fluid out till bubbles gone and fluid level is good. Reconnect pump plug/wire. Start car and check fluid level whilst running. Done.
