Posted for 46n2..

Does anyone know where the relay for the fuel pump is in an R32?!?!

Wiring diagram shows that between the ECU and fuel pump there is a relay and I need to know where this is asap, I think its in the fuse box, any help really appreciated.

Thanks guys...

sweet, I've been frantically looking for it everywhere. Everything I have read said it was between the ECU and the IGN. But I couldn't find any locations. The only other relay I knew of was in the boot there. Sorry to steer you astray mate.

pretty certain it' the one in the boot because i touched it while the car was running and it started to jump it's idle between 300rpm and 2000 rpm hOORAY! :rolleyes:

unplugged the relay and the terminals are corroded, so time to get a new relay.

two.06l,

I've recently done a full re-wire installation of a Wolf 3D into my R32 GTS4, utilising the factory relays. I think I know where the fuel pump relay is. I think you will find that the "relay" in the boot is the "fuel pump control modulator" (but I can't swear by that).

Blind Elk: do u know which of the 2 relays in the kick panel are which? just for future reference in case swapping out this relay doesn't fix the issue...

Going down to the servo to see if i can get a replacement today :P

Unfortunately, I wasn't smart enough to label them, or make any sort of written record as to which is which.

I think you need to get the genuine Nissan article, because they use a non-standard pin arrangement (well, they are certainly different to the Bosch types). Unless you are prepared to unpick the connectors from the plug to connect onto a standard Bosch type.

also, the relay is green, and the other green relays in the car seem to to have the same numbers moulded into the casing.

ie:

top looks like this:

3 o-o/ o-o 5

1 o-nnn-o 2 (the n's are the closest i could represent the image :rolleyes:)

I'm guessing both relays from behind the ECU are the same PartNo - they are just a relay after all.

Ive been working from the JPNZ manual - the engine wiring diagram is on page EN-289, if that's any help

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      The question then becomes - was there any fluid coming from that hole before you did the rebuild ?    You may not have noticed, of course.   Depending on how you did the rebuild, the possibility has to be considered that somehow (cleaning ?)  fluid entered that hole and is now being 'forced'  out by small movements of the proportioning valve.   From the factory, there's actually a small rubber plug in that hole but with age and under-bonnet heat it's quite common for it to 'go missing'.  That rubber plug is designed to allow the venting process but also to prevent 'stuff' getting to the area (prevent corrosion, etc).   The plug is also not available as a spare part AFAIA. Personally I wouldn't race and buy a new master just yet but keep an eye on the area to see if the 'leak' continues.   If you're concerned about brake fluid damaging nearby paintwork, cable tie a piece of suitable absorbant material over the hole and remove/monitor occasionally.    Operation of the proportioning valve and the brake master itself won't be affected, but also keep an eye on brake fluid level, of course. In terms of a new master, the genuine part is getting expensive, unfortunately.  Amayama is showing AUD900+.   I was searching recently and there's an aftermarket part available from Japan made by 'Parts Assist': https://zenmarket.jp/en/yahoo.aspx?q=BNR32%2bBM50&p=1 Whether it's any good I have no idea, although in my experience Japanese aftermarket stuff is pretty good quality-wise.   The above site allows overseas buyers to purchase stuff more easily from Japan but there are fees and shipping costs, of course.   The original Japanese seller page is here: https://auctions.yahoo.co.jp/jp/auction/p1197401228 Copper/Nickel is fine but I still prefer bundy tube and it's also cheaper.
