hey guys, just wondering if anyone could help me out with a problem ive got with my vp berlina. bit of background, around 10 months ago i got it converted onto gas, and got my alternator fixed a month ago. now my problem is it occasionally it doesn't start. The problem has been happening for around 6months. When i get in to the car and turn the key to the point before ignition normally the dash lights light up (ie. oil and battery lights), but when its not going to start nothing lights up. When i try and start it, turns over but never starts as if there isnt any fuel. it was very rare to happen 6 months ago, however has started happening more and more often. Usually if i wait a couple of hours and get in it'll work. Its not the immobilizer and it happens on both petrol and gas. Any help would be greatly appreciated.
