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

..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... 👍

Oh for sure, I'm just recounting my thoughts 😎 I'm not what you've got there to fuzt with.... likely my first idea was on the money -- rebuild or replace connectors. You can get a lot of connector stuff here -> https://www.rapidcables.com.au/ Didn't look in the boot of mine, because I replaced these when I renewed the pump (plastic of connectors had gone brittle) edit: what I used... https://www.efihardware.com/products/2120/Deutsch-DTM-Connector-Kit-6-Pin ...cheaper... https://www.ebay.com.au/itm/364900039138

Just got back from a little hands-on with a G58 Baron....I was thinking about this... ..best I can figure it, that pinny was tail-ended ...I didn't really think about the wiring, because all that mattered was the tank and pump cradle (I think I mentioned the pump itself I couldn't vouch for)...which didn't matter, as you said you'd be replacing the pump anyway.... ...'for some reason'....and I imagine this is the panel shop's doing... they've replaced the cradle wiring with a metre of 7-core trailer loom, and attached the loom plug (from a different car) to that. The actual cable run from the top of the pump cradle, to fuel pump harness end in boot, is maybe 60cm in length...so I've no idea why they did this... ....the connector in the boot of the pinny, is not going to help you here...because in theory, it should still be present on your car. On top of that, because they've done what they did, we have no idea which colours of the trailer cabling, have been connected to what on the fuel pump cradle (pump +/- , shield, fuel guage/low-level senders)... ...this means, best approach is to remove the pump cradle, and re-work it now ...not later. That is, if you were going to replace the pump, do it, replace the soft lines at the same time...and sort the wiring out (replace that trailer cable with the wiring loom off your old cradle)...

Obviously he got here on Monday, we managed not to hurt ourselves ....fuel tank looks far more useful now (instead of sitting in an unused car like it has been), but there's so much more to do... @25RBGT Forgot to say, if you need anything else off that car, just let me know...

It's a fun job...did a little write-up here --> https://forum.r31skylineclub.com/index.php?topic=159279.105 FTR, smoothed the idle out and the rb30 was more responsive...manifold vacuum at idle came up a bit (likely the base Orings leaking), and spark-plug colours evened out. An interesting little test, is to grab an eye-dropper/pipette and put a couple of drops of petrol in the old gauze filter, same again with new ones...see how long it takes to drip through 😃 Thing is the results are inconclusive because I replaced the injector connectors and fitted the intake runner spacer at the same time...but when you see & test the old gauze filters, there's little doubt this would've pushed fueling a little bit towards the thin side... ...btw... https://www.amayama.com/en/part/nissan/2891341l00 ....washer bottle cap, still available last time I checked.

https://www.autolinkparts.com.au/fuel-injector-o-ring-repair-kit-suit-nissan-skylin~46615 Fits many of the circa 1980s Bosch injectors. The gauze screen eventually gets (partially) restricted with fuel deposits, new base seal & Oring (they go hard), and the spray hole in the plastic pintle cap erodes after decades in service.

You should throw rebuild kits at the injectors while they're out...they pretty much need it anyhow at this age in life.. 😃

Did you check/clean out the Aux air valve & plumbing between it and the IACV and manifold?...

Suggest pulling the rear bumper and side garnish panels off, the silt's likely gotten in there...

He managed to find me over on R31SkylineClub forum ~ he'll be headed up here whenever to pull the good fuel tank (and other bits and pieces) from my spare S2 pinny parts car... should help the project & keep costs down 😃

Needs to be done for presentation's sake ~ especially the wiki, with talk some time ago suggesting the forum might go, and only the wiki being maintained. I've only been after that update since around 2018 or so, maybe I have to wait for the 10year anniversary 😃

I knew you lurked here ...<grin>... the SMF stuff I'm not terribly concerned about (but should be updated), it's primarily the mediawiki software I've wanted updated...for years now, since Session gave me access there and I was looking to clean it up (consistency wrt presentation)...and I couldn't get that to work properly, which I found out by cloning the wiki and setting it up under the latest mediawiki release, was because it's the actual version of the MediaWiki being used causing all the problems wrt presentation....grrr. Then of course, the image repository which the wiki is tied to, has whacky permissions linking back to the forum SMF software DB, and because I don't have admin/mod privileges there, there's a number of things I can't do within the wiki...like...ie; fix/include images for the wiki....grrrrr.... 😃 AFAIK, only wheezy has been maintaining this stuff, (he knows all about the above para), but life gets in the way (kids, vocation)...and like, now he's bought a sea-going vessel, so 'gone fishing' springs to mind B^) You have a knack for understatement ...lol...

Indeed 😃 Appears the site is back up now (migrated not updated) - kudos @funkymonkey & @PranK

Cheers mate, @acsplit would know... bit of a pisser we never got notification, but not surprising. I was primarily concerned with one 70+yo member there, who's halfway through rebuilding a re4r01 gearbag and relying on my help in that regard. I'm hoping wheezy might update the forum software at the same time (especially the media-wiki stuff).. I guess we'll find out. Kudos...
