      there is also crank sensors that can fault on the b gsi and cut the fueling

      to check it connect the car to opcom or tech 2 and look in the data logs for the engine rpm signal if this is at 0 whilst cranking the sensor is dead

      Belt ok but may have jumped a tooth or to by the looks. Only compresion in one cylinder. Going to re time it and hope for the best. If not will be breaking. Irmischer import.

      If its 2 teeth forget it matey iv worked on hundreds of these engines in all variants 2.5 2.6 3.2 etc and there aint much movement on the timing.

      if you retime it and it missfires and throws up cam sensor fault you know its well goosed and if its only cot compression on 1 cylinder tbh it prob wont start
