Most of the time the car is cranking but not starting.I might guess it could be coil pack , air flow or petrol pump. I might need some expert comments please. Thanks in advance

the car completely stops when i was @ traffic lights ; is that a symptom of bad fuel pump (when slowing down or complete idling ; its playing up with rpm drops) ; before that it was playing up with rpm when i slowing down (last 15 mins before it completely shuts down) . the cars was ok till that afternoon .....................is it a common problem with r33 gtst ? :) thanks

check the basics, check airflow meter, check the plug (common bug on VL which has similar AFM)

check fuel, check fuel pump, check for any idiot lights, are you trying to start the car in D?

thanks for your replies .........yes...AFM is plugged in , no unusual lights , half tank of mobil 8000 :( ; the car is not starting at all ...now the battery is dead so i tried with battery pack still no go... but cranking ok ... i might try fuel pump.....

What is the brand of stock fuel pump and how much are they.......i don't want to go for modifications.....thanks

self diagnoitcs. it helped with my problem. my car was really hard to start, running like crap, ect. did the diagnostics and it come up with ignition curcuit, i was pretty sure it wasnt coil packs. i changed the igniter and started first time better then ever. my skyline is a r32 so bit different to yours. your igniter is in the coil packs (tell me if im wrong?), so change the coil packs and see what happens.

just a thought.

When my walbro pump acts up, I smack the cover in the boot with a hammer while someone cranks the engine and it magically fires back to life.

If it is your fuel pump playing up, I'd certainly recommend getting a bosch -_-

I also need a new fuel pump, same model skyline, any recommendations on what aftermarket pump to get?

Definitely not paying for the Nissan one!

Ignoring what the previous guys says about his alleged walbro pump issues.. if you are not chasing huge kw go the Walbro pump upgrade.

They are a direct factory fit - no stuffing around & good value for money, just make sure you get the real thing from a reputable dealer.

Yeah sounds good, direct fit is a plus, and not chasing huge power at the moment, so Walbro it is!

be wary of walbro.. go bosch if you can

have had 2 die on me already and im not chasing big power.

walbros have been replaced under warranty and have one in now and has been going 6 months and starting to get real noisy. never let tank go under 1/4 of a tank so never starved it for fuel either.

-1 for walbro

    • Good luck on the weekend mate
    • 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
    • Welcome to SAU, what are you looking at buying?
    • 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
