Hi I have just bought my mk2 gti I have replaced the lifting pumping and fuel lines I have petrol going to the engine ,the car is trying to start but just splutters and won’t fire up any ideas what could be still stopping it from starting I have also cleaned all the plugs and by leads ?
Ok. First off, 8v or 16v, digifant or KJet? I'm assuming Digi 8v when you say lift pump, that being the one in the tank. There's another, hi pressure pump externally, that needs to be in good condition. Next, has it started whilst in your ownership? If so, what if anything has been changed? Cleaning plugs that have been fouled often doesn't work, new ones are always a safer option, but check for spark before you refit. Can you check the ignition timing? Also the main rubber inlet boot, that it's not torn?
