57 plate 1,6 petrol zafira, approx 40000 miles.
Emission light came on last week and car started running rough.
I assume front o2 sensor in manifold is u/s as engine sounded like the mixture was too rich (misfire etc)
I have changed sensor (aftermarket part) and car won't start.
It turns over but won't start.
I have left the battery disconnected overnight to reset ECU, but it makes no difference.
Any ideas?
Thanks
