So I bought a nismo fuel pump for my r34 gtt pretty straight forward installation as its a direct replacement pump. Put everything back together went to start the car and wait for it nothing. Can hear the pump priming but the engine isn't ticking over at all.

Any ideas? Nothing is leaking pump is priming so why isn't it starting?

Going to have another looking in the morning so hopefully i can work it out.

Thanks

yep was running fine before this and yes all i did was the fuel pump. By not ticking over i mean it doesn't even attempt to start nothing.

I have a nistune but surly this wouldn't effect it to the point of the car not turning on

Did you prime the system lots before turning on? If some of the fuel has drained out of the injectors then they sometimes take a bit to get started. Key on and off a fair few times is the easiest way to do it. Key on, let it prime, key off, repeat

Also change your fuel filter in case the new pump has stirred up some crap thats got through the sock (not likely but id change the fuel filter anyway)

If the car won't start:

1) Check battery voltage, you need at least 10.5v while key on start (yes actually turn it to START, even though you think nothing is happening, what could actually be happening is there isn't enough voltage to bring the solenoid in to engage the starter)
2) check fuses

3) check start relay (30 needs power, 85 and 86 need to energize a coil, so a test light between them with the key on start should light it up)

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
