Post by: pascoe on 04 September 2010, 22:52

hi i have a 1.8 8v gti and when its warn and at high revs over 4000rpm or low revs under 2500rpm it judders like its being starved of fuel but its got a full tank and i was wondering if its a fuel pump problem, injectors or sumthing, any ideas

first thing I'd try personally is the fuel filter!

I doubt its the fuel filter if it only happens when warm.

Is it K-Jet or Digi?

Airbox is the biggest giveaway I've always thought. Someone correct me if I'm wrong.

Digi - Has the box maf sensor on the top

K-Jet - has a load of hoses coming from the airbox

Hope this helps.

This may help with the fuel pump diagnostics too.

ok thanks i have a new fuel filter now and will fit it wen i get a chance, but i could be the lift pump from that thread but i cant hear any buzzing it just gets starved of fuel especial when going fast and after.

Why don't you **test** the lift pump before changing it, otherwise you are just replacing parts blindly.
