Got this r31 silhouette flood car to rebuild.

[25RBGT]

Finally getting around to changing whole cold side.

(Look at that sludge)

lets see where this leads once it’s all together tomorrow.

..m'kay.... I see on my phone you're having difficulties interpreting the artfully hand drawn R31 wiring diagrams... you wouldn't credit it, but they're actually more accurate than those colour diagrams in gregory's and the like...

...for your purposes though, the wiring colour legend is on sheet 1....

....the fuel pump connector is top right on sheet 2....

...pin1 (black) goes to chassis ground -- pin5 (light green/red trace)...

The best way to navigate those drawings, is to open them up in whatever image manipulation/paint program you like, and use the straight line/ruler  tool (with a highlight colour) to trace along the wire lines...not hard, no rocket science involved...

Fun facts:

The OEM diagrams are drawn to top trim level spec ~ so for example, you're looking at Silo spec wiring, but the base S3 Executive trim is also covered by the same drawing (base models just don't have all the add-on luxury bits)

One of the more sublime bits of errata, is this bit...

The wire splice between pins7,14 doesn't exist (red) -- the bridge on the cluster PCB between the same pins (green) does exist...but it's not 'there' physically...it's actually more towards the center of the PCB, exactly at the spot where they tend to crack...and if it does, only half the dash lights work... can drive you nuts chasing it ; don't ; just solder in the missing splice...

These are 'intentional' soldered and taped splices inside the loom(s) ~ there's also unintentional splices like this, due to manufacturing process when a spool of one particular coloured wire runs out, and they splice in/on a new spool. Those splices above are in the loom, LHS, underneath the front guard panel (remove to get at loom)... if water's gotten into the looms, you can expect corrosion at these splices ... keep this stuff in mind, if in the future you get any weird electrical faults... 👍

Nice write up solder thank you. 
that problem had fallen into another days fun. I wanted to get this cold side in and turned over so it was wired up the same to get a start.

no luck I got a couple of cough’s before the battery died unfortunately.

we have some wether on the way and I’m back to work, I will order your plugs and re wire them in the near future. 🤙

[25RBGT]

As promised………… the first start. Rough and a few bugs to work out. Still she lives

[25RBGT]

Yeah I noticed this just now. No doubt she will be running smoother next start😂🤣😂

Similar to a video I watched on YT recently. They were like "that sounded really weird..." They took it one step further though. They forgot to put cylinder 1 spark plug back in after checking timing.

Haha yeah mate, I didn’t notice till I watched the video myself haha

Motor done back together, surprised is a understatement with this rb30.

just think 10m under flood waters for a couple weeks, 20lt water inside the engine for 3years.

cleaning the cooling system installing new plugs leads and overflow bottle and then I’m closing the bonnet moving onto the restoration of the body. 
 

already finished few external pieces for putting the puzzle back together.

this has been very enjoyable, frustrating at times definitely. Moving forward with my silo sub!!!

thank you to everyone that has helped me so far, ✌️

[MBS206]

Vids of skids not loading.

 

You know it's at about this point in time a YouTuber would have taken it to the drags, or on a 1500km road trip right?

[25RBGT]

lol I don’t care what they would do man. The car has no functioning gearbox. 
i have a job and im not made of money. Doing it with my own two hands

[25RBGT]

New leads, over flow bottle and windscreen washer bottle cap. Gear box is getting oil shortly so I can drive it around my yard. 
running nicely! 

R34 must be getting shitty I’m spending all my time on the r31. It shit a brake switch yesterday. They are not fun to get to haha

best get into the power steering and brake system next. ✌️

Steering rack might be full of water, same with gearbag....

[MBS206]

Can't remember if you've done the diff yet, after my 33 went under water, it was full of water a long while later.

Drained and refilled with oil.

 

Mine hasnt been moved under its own power yet though, but inspection camera before refilling and it looked like it should be all okay. Let's hope bearings are fine ha ha!

[25RBGT]

Yeah gear box was not full but did have some water mixed with the fluid, steeering rack and brakes are next as the box is getting fluid to see if it will move around the back yard without the assistance of my patrol dragging it.

the box or motor I’m assuming will be in very used condition and shortly give up. But who knows. 🤞

i lsd got fresh oil and the old oil was not contaminated with any water. 

[25RBGT]

Just another step forward. Neary time to put front end back together after I get this box sorted. Shortly 

[25RBGT]

Cold start, battery is one I got with the car and dead! Jumping is required as it won’t hold charge and yes the alt is working 

[25RBGT]

First movement under her own power.

One small step for an R31...one giant leap for a submarine?

Been a bit of work to get to this point, definitely a huge milestone for this sub✌️
