R32 GTR doesn’t want to run

So I’ve had my R32 GTR for a little over a week and have been driving no problem. I was driving around today and stopped and got gas and drove off with still no issues. I got to my last stop and shit the car off and was gone for maybe 10 minutes. Come back, turn the key and let the fuel pump prime and go to start her up. She rough idled for about 5 seconds before dying, now she will turn over and die instantly. I’m pretty lost on what the issue could be. Also a relay in the trunk by the tail lights  clicks ever 10 or 15 seconds when the key is turned to accessory.

When you say 'it turns over and dies instantly' I guess you mean it does start at least momentarily, rather than just turning over and not starting?

Starting with the relay, there are 2 in the boot, either side of the lock. The larger one is for 4wd and is often the cause of regular clicking, which is generally a problem with the accumulator needing to be recharged or replaced.  The smaller relay (either green or blue, can't remember) is the fuel pump relay.

It sounds to me like a fuel supply problem and the most obvious reason is being our of petrol. If not I'd get a multi meter onto the fuel pump terminals to make sure there is battery voltage for the first 3 seconds when someone turns the key to IGN. That should confirm there is power where there should be which would say dead fuel pump. Otherwise if there is no power there, there is some electrical issue so you'd look at relays, fuses to the fuel pump

Yea the green relay in the boot is the one clicking. I’m leaning more toward fuel being the issue. Just not sure to start with the pump or the relay

Well....check under the bonnet for a green relay you can live without for a moment and swap it into the boot....

UPDATE: So I just let the car sit for a few hours and now she starts up. But the engine seems to be struggling in lower Rpm’s but does fine in higher revs around when boost starts to kick in.

Pull the fuel line off the rail and see what happens when you turn the key. Could be blocked filters or as Duncan says pump on the way out (or coils or CAS or lots of things but start with the fuel supply).

      Mistakes were made, my R34 Story

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
