the R's not happy

[SIR GTI-R]

Ok lads i've had a few stumbles at this point before but today Bloody hell
i'd just picked up my 4 point lower brace and was just pulling out of a intersection and stuck my foot in it all was ok till she hit 3400 started missfiring and as i looked in my mirror there was a Huge cloud of black smoke behind at the intersection on the way up the hill as it came on boost and got to 3400 again it lost power didnt want to climb the hill as i rolled out of the gas it came right slowly putting the gas back down it did the same revved fine at home at a stand still

did a fault check showed all clear

I was thinking det sensor

:S Help guys i'm lost

Sounds like a massive boost leak, the turbo keeps pulling heaps of air in past the MAF but loses it to the atmosphere rather than going in to the engine, therefore the ECU drops in far to much fuel = really low power & crap loads of black smoke.

Check all the intake plumbing, there is most likely a hose blown off.

[austingtir]

Get a 2.5" round piece of tyre innertube with the valve and clamp it to the metal inlet to the turbo.
Pump it up leaks will be obvious.

Deff sounds like piping leaks though.

Ok went to start the R ths morning was running on 3cyls Maybe
wouldn't idle at all my greddy infometer said 45 degrees timing and then the engine stalled
Cheers guys i had a look yesterday but yeah i'll have to pressurize the system tho i've got a 3" intake to the turbo i'll have to sweet talk the boss to do some s/s welding for me
cheers guys

Im guessing spark plugs, leads or dizzy

Mine did EXACTLY what yours is doing about 2 weeks ago and it was one of my spark plugs. Replaced the set and it was good as gold.

[SIR GTI-R]

Good s**t mate i'll pull them out tommorow and have a look replaced the cap rotor and leads a few months back and the plugs would be the only thing i haven't replaced gapped them awhile back but thats it

[SIR GTI-R]

Ok seems theres sweet Fa fuel pressure
reads 5psi on the fuel reg Causes I'm thinking Earth ?? maybe blockage

Pulled the plugs out Dry as a bone
after the amount of cranking it had they should have had something on them
so with the datascan i activated the fuel pump and all i got was 5 psi
so its got a walbro 500hp one in there should be fine any thoughts lads

[mungyz]

Block off the return fuel line AFTER the fuel pressure regulator, turn the fuel pump on, you should hit max fuel pressure for the pump.
Obviously if this is still ~5PSI you have a problem with the pump, if it is way up there like ~ 70 PSI you have an issue with the fuel pressure regulator.

Just so happens I have a brand new NISMO FPR for sale adjustable as well

[Heretic]

Take the fuel line off before it gets to any restrictions in the engine bay and direct the hose somewhere where the unburnt fuel is not going to be dangerous, then get someone to turn the car on for a few seconds and see how far the fuel goes

amateur

[Heretic]

No need to worry about if the gauge is reading right - if it trickles out, pump screwed, if you can shoot the neighbours cat, pumps fine

[SIR GTI-R]

yeah blocked off the line and Bearly managed to get 10psi theres a shiz load of Crap in the line So i wonder if the Craps Shagged the pump

[SIR GTI-R]

well i pulled the pump out yesterday and found the cause
the Pickup Fell off refitted the pickup away she went as the pickup that came with the Pump was short and wouldn't get to the bottom of the Tank i used the factory one and well simply after 3 years of thrashing it fell off Out Come the cable ties

[Heretic]

So when you coming over for that drive lol

[SIR GTI-R]

Maybe next week Bud whats the plans lappys still Working fine too by the why Thanks again
