Car wont start

[JayA]

Hi,

My car won't start, it will turn over but not fire.

I've tried jump starting...this did nothing (so rules out battery issues I think)
When I push start it it starts fine, and will then restart when warm. (this rules out starter motor?)

Also the exhaust gas warning light has come on since I push started it.

Anyone got any ideas?
Thanks

to clear up a potentially confusing point...
When I said "it will turn over but not fire", I meant it will crank but not turn over
