So my R32 GTR doesnt want to start anymore. It was working ok until it started dying randomly and would just lose power. Once it died and wouldnt start, so I thought it could be the afm's, and since I had some spare I tried swapping those in to fix the problem. The engine started and worked really good, which was good until I turned the car off and next time I tried to start it wouldnt start. It would never stay on for longer than 4 secs since then. So called the raa, he checked the wiring to the fuel pump while I turned the ignition. He said power would come for 4 secs before turning off. So my question is, is 4 secs normal for priming the pump and then its not powering anymore because the engine isnt running or should it continue longer? My next step is to power the pump directly and if that works ok, look for boost leaks.

Yeah thats what I meant, i was cranking the engine and he was measuring it. I couldnt see any smoke coming out of the exhaust. And it won't run at all now, its like there is no petrol coming.

Ok found it. Do I do anything with this box or should the fuel pump just be grounded to the chassis or this box grounded to the chassis? Also got a new question, I found a random purple wire going the length of the car and it goes into a plug in the kick panel. I took a pic can anyone recognise this plug?

And another question, what is each plug on the fuel pump? The raa guy tested the brown plug, should have he been testing the grey one on the right? Anyway i havent had time to directly attach the fuel pump to power, but I am not sure the pump is the problem anymore. I got someone to crank the engine today while i listened closely to the pump and it was making a small humming sound which sounds like to me that the pump is fine. How do you test the wires with a multimeter? Next would prob be check that there is fuel pressure, but now I am starting to think maybe its no spark coming. SO then how do you test the spark is good? I have never had to test these things on a car before.

    • At least yours have parkour down pat. One of mine will still trip over his own shadow and fall over... He's a special type of cat... Ha ha ha
    • 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.
