Seat Cordoba Year 02 starts when you want

I have a Seat Cordoba Tour 1.4 16v.Gasolina del Year 02 Mod. Ancient (that year the new came out) and starts when he wants, that is, he spends good days that he does not want to start, after giving the starter in the starter in a very slowly, it seems even that at that time some cylinder fails and in one moment to another it is correctly clear how you have the stepped accelerator, a great acceleration occurs. I discard the lack of fuel because after this there is a strong smell of gasoline.

Verify the compression of all cylinders
then if you say that it after several days takes good to start if your car has an electric pump verifies the fuel retention valve or fuel filter.
Then verify if any empty is loose or open or multiple of broken or cracked admission.
then verifasiososostema of ignition. If you already did the aforementioned I hope you have solved

Ideally, when you do not start if there is a spark presence in spark plug cables, you must be careful that there may be the presence of fuel but if it is much or very little it will also affect whether it starts or not.

I think you have a problem with the dead point sensor (also called motor steering wheel sensor). When it does not work, or does not correctly censa the position of the first piston, it does not give the signal so that the centralian mandates spark and the start occurs.
Luck!

The first thing is to thank you for the message and the dedicated time.
I cannot rule out anything, but the strong smell of gasoline that leaves me to think about that, fuel into the cylinders, the problem is that now it does not fail and no checks can be made.
Thank you very much for the information.
