Neil's R33 Gts-t Build

[Duncan]

From there, it was just a quick electrical check, prime the oil and start her up

Which, is not what happened.

1. Bloody seppo Aeropro battery holder. Not only was it too tall for the battery (which I'll forgive them for, I have another battery the same nominal size that is taller than Neil's one, but the bracket is a fixed height so the battery was spaced up) But the thing that really shits me is the hardware to hold it on requires a 7/32 Hex key. WTF. No-one will ever be able to remove or install the damn thing without a hex key they don't own

2. Kill switch no longer worked once the console was installed. Neil mentioned above he had to adjust the length but it no longer cleared the console once installed. Sorted.

3. Suspiciously, the brake light holders were hanging in the boot with no globes. Sure enough the stopper on the brake pedal was missing so they are always on unless the kill switch is activated. Will pick one up tomorrow (turns out 32 and 33 don't use the same stopper)

4. All that sorted, I turned on the kill switch, turned the key to ACC. Nothing. Turned it to IGN. Nothing. Checked some fuses and found the main IGN in the boot was missing which improved things once it was replaced. Now ECU and dash lights turn on with IGN but still no fuel pump.

5. Turned it to Start....ECU on, no fuel pump, no starter. Plus the voltage dropped straight to 9v.  I suspect the starter is f**ked but am going to have to work through it all and see what is happening, really looks like more than one issue.

Does anyone have the R33 fuse box key with the circuit it sources from (eg BAT, ACC, IGN, SRT etc) and supplies? I can find a translated list showing Amps and circuit without supply circuit, and I can find supply circuit without Amps and target circuit.

Silly question, as I bet you've checked already, but the motor turns over by hand yes?

I suspect Neil has a spare starter, though if not, I believe I have a spare R33 (or two) starter.

[Duncan]

lol yeah I'll check that, reminds me of the LDV thread!  I don't think that is the problem here, the starter doesn't even solenoid click.

I did do a super quick test by removing the starter motor's power cable from the engine bay fuse box and the battery voltage was still 10v, so something super fishy is going on.

BTW here is a R33 fuse box table I threw together from a few sources....use at own risk!

Sounds like the solenoid might be cactus, if the solenoid trigger wire was still attached (and it was just the main power to the starter itself remove).

Just to provoke Neil haunting me for the rest of my life... Have you tried tapping it with a hammer while someone switches the key to start?

This might work for the fuel pump too... 😛

haha funny enough I did ask him wtf he had been up to with the electrics....but no answer

I'm sure he has left signs, or, he is looking down, laughing

That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes

He'll be looking down and swearing about "the damn apprentice" for trying to convince Duncan to use percussive maintenance... 😛

Nah he was mega organised, the sort of guy that put (almost) every tool back every day, it made trying to work out where things were up to possible. 

My shed needs a swedish death clean, I would have >20 part done jobs, its particularly hard to collect all required parts for a job ahead of time when you can't just pop into a shop and grab things

[Duncan]

As you can tell from updates....I haven't had a lot of shed time lately.

When I'm on this though, I feel like I'm reliving Neil's last days. Everywhere I go on the car I seem to come across something he was working out.

When I went up to his place just after he passed, I noticed he had a RB starter motor in the vice. And sure enough, this was my shed today

So, last episode I mentioned the battery had 12.4ish volts but when I turn on the kill switch it drops to 9ish volts. Even with the stater main power removed, same.

And yep, when I removed the solenoid power from the starter, the voltage jumped from 9 back to 11.7ish. Thus my testing the spare starter this arvo. Spare is good to go, just need to throw it in tomorrow.

I'm not convinced that is the only issue as the voltage still drops from 12.4 to 11.7 when I turn the kill switch on, but first things first

OK, starter changed for a spare without much trouble.

Neil had kindly left space to get to the top starter motor bolt from above with a long spanner which makes the whole deal much easier, and everything else was neat and easy to get at from underneath.

Once the starter was changed everything was good, unplugged the CAS and turned the motor on the starter to make sure everything was free and happy.

Onto properly priming the oil and first start.

I'd picked up one of these oil prime kit from Boost doc a while back and this was my first time using it.

While I'd organised all the fittings to hook it up to my GTR (sump plug to -6 feed and -4 T to tap it in and retain the oil pressure gauge, neither suited on this car as the oil pressure needs to T into 1/8 NPT not -4 and the Aeropro sump has some massive drainplug not that factory whatever it is. So, waiting for a couple of fittings, then I'll prime it and do first start, hopefully next weekend.

Other than that going well, there is very little stopping a final alignment, tune then shakedown day
