Running Issue

[quote pid=160 author=Dougy date=1204799888]Well got up this morning started driving to work did 1 mile and smelt petrol it was pissing out of the fuel pump

Note to self never use jubilee clips[/quote]

ive had jubilee clips on mine and theyve been fine... so far lol

[PeteG40]

sorry dougy, didnt reply to yr test... normal vag ones are single use.. get proper fuel pump clips if you can - far easier to work with!!!

Hello guys I'm back again and i'm proper puzzled now really need some help

Changed the fuel pump and suprise suprise it didn't change anything but strangly it made an even louder squeel than my previous one.

Now car still runs like shit, unplugged lamba and sounded like it was running better but made no difference to the running still slight drop in rev's above 2.5k.

Now apart from the above other obvious faults is terrible fuel consumption I'm getting around 35 miles to £10, car smells of fuel all the time running very rich and when you put your foot down there is just loads of smoke which I presume is the fuel.

Has anyone got any ideas cos i'm all out

Thanks

hmm does seem strange, id try a different lambda probe first, maybe the probe makes it run shit, and with it off, it will over fuel so run shit?

it can only be so many things really, all which can be swapped!

if not probe then do the blue temp one...

Going to Rae's tonight

Hopefully get to the bottom of this

Will report back

Well went to Rae's last night and hooked it up to laptop to try and find the answer to this problem

Alternator = Fine
Lamba = Fine but sluggish
Timing = Fine
Dizzy = Fine
Battery = Fine
Fan = Was wired up backwards explains slight temp issue (just another problem caused by the person who did the conversion)
Blue temp sender = Fine
Knock Senor = Disconnected

So we could not pin point the exact problem

But it did narrows it down to a few things to check

Coil
ECU
Fuel

Anyone want to take bets on which one it will be??

or can think of anything else to check

[hayesey]

my vote is on the ECU because that's what was making my car get the hump a while ago till I replaced it!

[Dougy]

Well suprise suprise its not the ecu

Car is running very rich and my money is not on the injector rail

It has to be some problem with the fueling system

Any ideas guys

[PeteG40]

what chip does it have?

[Dougy]

had a standard one on before then switched it with a Jabba one

[Dougy]

Right this is starting to get right on my tits now

Only thing that it could be now is the Injector Rail or Intank Fuel Pump

Changed the fuel filter yesterday and made no difference

Could an injector rail cause this much trouble?

[PeteG40]

in tanks are £20 new...  i think i might have a fuel rail with injectors you can try if needs be

[Dougy]

I have injector rail to try its the intank one I don't have which I want to try first as the pump other fuel pump is still making a noise suggesting that theres a block intank pump
