1.8 Astra - cam sensor - T1mb0
My Astra 1.8 is suffering intermittent starting problems. Sometimes it starts first time no problem but occasionally the engine turns over for a few seconds before firing. It has never failed to start but can be quite frustrating. I have been told by a well meaning colleague that it may be the cam sensor needs adjusting. The vehicle has had a top end rebuild and seems to have started this problem. Any thoughts.

Sorry, these are not 'adjustable'. They work or they don't. Cam sensor failure isn't uncommon, but should bring up the Engine Management Light when it fails, and sometimes puts the engine into limp home mode. When one failed on my Vectra it didn't have any effect on starting.

Also check the earth to the coil pack - if need be, run a new one directly to the battery earth, it isn't a long cable run.
