Possible Fuel Contamination... Help!

[kones]

Hi everyone, I have a R32 GTR that is a little sick, I think it could be either shit fuel, fuel pump as kicked it in, or a problem with the computer. It has a bosch 044 fuel pump, power FC, 650cc injectors. Always filled up with 98 octane fuel

So i made it about 5km down the road then started to couch and splutter, so pulled in to side street. Next thing i know is that it will only rev to 3k RPM and very roughly at that.

When i put my foot down it stalls and chokes, i have to feather the throttle to get up to to 3k.

I have no idea what could have brought this on.. it came out of the blue while i was driving and everything was fine..

Iv filled her up with a bottle of octane booster as a suggestion from a friend and that has seemed to help a little

Any possible tips of ideas would be greatly appreciated

Thanks!

sounds like fuel pump failure... or blocked filter. check both out.

Whats the best was to check the fuel pump is keeping up?

I know its on i can hear it.

It still uses AFM's? Checked them?

AFM's are fine.. i disconnected them while running and she just died

Have a look on the pfc hand controller. Watch the afm voltages. May be a faulty one
