Hi everyone, would really appreciate some experienced- based advice on next steps to address this problem.

Car wouldn't start and the problem was traced to fuel starvation. On removing the pump it was found that the fuel line rubber had perished so it seems the workshop that installed the 044 used fuel line that was unsuitable for an intank application. 044 mesh was clogged and once unclogged it worked fine. I haven't seen the rubber yet but I'm told it just falls to pieces and dissolves. No indications of a problem until it refused to start recently.

Plans are to:

Clean tank

Clean injectors (maybe overkill?)

Flush everything from the fuel rail back

Replace filter

Replace pump (with a Walbro)

Any thoughts on other things to do?

Just flush tank, change fuel filter (maybe every tank just to be safe, they're cheap enough), change pump, and use proper submersible fuel hose.

Also that shop, or whoever did it - should be shot.

Get a Walbro 450.. they're good pumps, quiet, work well, flow well.. if used in a very basic/stock application the OEM wiring is ok... start to up the boost make sure you run a proper 60amp relay fed directly the battery through a 25amp fuse.

+ make sure you install a dose pipe, and tune it.. more bends & more length more dose :)

sorry I let you guys down, I've repented and edited the post.. forgive me SAU

Definitely agree with point 2 although that could be too good for them. The guys who found it were only second to me in being pissed off.

We've got a 450 lined up, and the direct feed/fuse and relay have been installed but not sure about what to do about the stock loom between the relay and tank lid. The Fuel Pump thread had some discussion on the wiring between the relay and the plug in the tank lid but I couldn't see where anyone had come up with a solution yet. I was thinking about running a heavier gauge feed between relay and tank lid plug, and then from the underside of the plug/lid to the pump on the assumption that the plug pins could take it.

I am currently having issues with getting power through the fuel tank lid to a Walbro 450, all started after the wires inside the tank shorted. Have tried two lids and can't get power through reliably, am now guessing the plugs on top and/or bottom of the lid are fubar.

Now considering ditching the factory wiring plugs and putting two bolts straight through the lid, sealed of course, with eye connectors on top and bottom.

      Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.

      I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
