My girlfriend's mk3 has been having some electrical issues lately which drains the battery most days but when it's jump started off another car the engine will fire but it stalls almost instantly. This doesn't happen everytime as her dad had it running only a few hours ago but when we got back from autosport today in my mk2 we went to try the mk3 which again had a flat battery. We connected it up to her dad's v*ctra and the engine started up but wouldn't run. Anyone have a suggestion of what it could be??
