Start issue with Citroen C4 2005

[Tehome]

I have some issues with my Citroen C4 2005 model, It wont start.
Engine is cranking, so battery and starter is good. Have checked the voltage, 12 volt.
Took out all the spark plugs and checked that all ignites. Smell gas from all spark plugs so I believe gas is comming in.
Also checked that there is comming gas to the engine by disconnect the hose, and there it is comming gas.
Also check the air filter, and this is clean.

Anyone has a clue what the cause might be?

Have you scanned for trouble codes?

At this stage, could be many things but trouble codes would give you a start on where to look.

Does it have trouble starting with hot or cold engine or both?

Does not matter, wont start at all. No i have not yet scanned for fault codes, dont have a scanner. But that i must get.
