Hey everyone

About a week ago i tried starting my car a couple of times, it wouldnt start. I realised it had no fuel :) , so i put 10 litres in

and tried starting it again. Nothing, the gauge read there was a decent amount of fuel but it didn't start.

The engine cranks but it doesn't fire.

I jump started it and it didn't start.

The engine is definitely getting fuel.

The injectors are working - used crank angle sensor to check.

And there is spark

Im running a wolf v500 ecu i swapped it with the stock one and still didn't start, i used consult but consult wouldn't turn on????

What could be the problem??

The engine cranks but it doesn't fire?? Could it be a CAS related problem?

Could i have damaged something trying to start it with no fuel?

If your sure you have a good spark and fuel getting to the cylinders then perhaps its IGN timing? I would have thought it would still cough and splutter. What was done to the car up until the time it wouldnt start?

we checked the fuel and its defiantly pumping into the fuel rail, then we checked the injectors by pulling the CAS out and spinning it and the injectors were ticking fine but im not 100% sure if they are working while cranking.

we pulled the first plug, it had a fair bit of carbon on it but was still sparking fine, do you think it might be worth checking the rest?

as far as i know the car was parked and nothing touched, but it was running on low fuel lvl's for a while not that it should matter?

im thinking maybe the fuel is bad but still i'd expect it to start.

it was interesting that we couldn't get the consult to work, so it may well be an electrical/ECU problem?

Having run out of fuel, you may have picked up a heap of crap which is restricting flow through the filter. You may not be getting sufficient fuel pressure to provide enough fuel to start.

What does the Wolf say while trying to start (injector time, ignition timing, etc)?

I didnt check the fuel filter, but the battery is reading 9.9V and when i jump start it the battery only goes to 12.0V

Ignition was 30.6

and Injection was 24.88

thats with the key at ignition

When i try starting it the wolf hand controller turns off.

thanks

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
