i have a volvo s80 y reg non turbo a friend has put a new timing belt and cam v v t now the car will not start at 1st thought timing must be out but have had this checked by 2 garages now all which say the timing is spot on so then thought maybe the timing had been out and bent some valves so removed the head and had it all tested and thats come back ok put the head back on still not starting the 1 time it did start after a long timing turning over it would tick over but would not rev up since then its back to not starting again if anyone can help it would great . cheers phil
