Are the plugs in firm? Is the injector loom plugged in properly further back?

if the cam sensor was faulty i thought it would not start at all if i crank it over enough it will eventually start and as long as i keep revs on it it runs but a bit rough will idle after awhile but the light staying on

it will start if the cam sensor is faulty as the crank sensor will let start,and vise versa

No such thing as an earth on a car....unless you have connected the body work to a bloody great big ground spike  :y

Its a common mistake  ;D

but as an electrickery bod you're a pedantic **** over the this term. In all automotive manuals, they refer to the other connection of the battery as earth, whether that's a negative earth used on modern cars or a postive earth as found on cars years ago.

have a look in the back of your Zafira Haynes manual, all the simplified diagrams show a even though you don't have a big  earth spike in the ground.
