My Corsa (V reg, 1.2 GLS 16v) will not start. When i turn the key the starter motor turns but the engine won't fire. For a while it would start ok if the engine was warm but never if it was cold, but now it won't start off anything but a push start (bump).
So far I have changed the spark plugs, changed the starter motor and had a brand new battery, none of which has helped
Somebody please help!
Corsa still won't start?
I would have told you to replace all the things you have allready replaced AND one more thing.
Check into your fuel system. I bet you a dollar the fuel isn't getting to the intake manifold and that is why your car isn't starting. You might have a clogged fuel filter that isn't letting enough fuel pass through it. You might have a bad fuel pressure regulator which is not providing enough fuel pressure or you may have a dirty clogged up carb. Or if its fuel injected or has a throttle body injection system, the injectors may need to be cleaned or replaced. You may also have a bad fuel pump which isn't pumping any fuel at all. If so replace it. A good way to check if you car isn't starting because there is not fuel pressure is by taking off the air cleaner if you have a carb. and having someone turn the ignition key while you pour A LITTLE BIT of gasoline into the carb from the top. Don't put to much gas or it will flood the engine, and you will have an even harder time starting it.
If the fuel system isn't the problem then it should be a problem in your ignition system. Your alternator might be bad, its not your battery because you already replaced it. It might be the distributor, ignition module, ignition coil, or the spark plug cables. Its not the spark plugs themselves because you already replaced them.

did u try a new key switch
Trade it in for a Ferrari.
you'll need to check the fuel filter but I think its more likely to be the coil pack.
get your coil and all your leads changed - a coil not pumping out quite what it should will result in poor cold starting
it should cost a hundred quid or so to have it done for you - its not a big job on a corsa.
get your timing cheked also
does it make a quiet whirring noise?
have you tried pushing the car a few feet forward while in gear? it sounds like the forks in the starter motore arent lined up. Moving the car in gear with spin them round a bit, and hopefully line them up, enabling the motor to engage the engine etc.
Your vehicle could be suffering from good old %26quot;coil robbing%26quot; wherein there isn't enough juice in the battery to spin the engine and spark the plugs.
This can be caused by either a faulty battery, faulty starter, faulty coil pack, or a faulty igniton amp.
You could also have a fuelling problem such as a weak fuel pump, clogged filter, faulty coolant sensor etc...

It could be a fuel problem. Does the exhaust smell of petrol after cranking the engine?
