Technical Fiat Bravo 1.4 66kw starting problem

[Hulskero]

Hi,
I have an issue with a Fiat Bravo 1.4i 66kW. The car stayed in the garden for 1 year. It has a problem starting when the outside temperature is around 10 degrees. Sometimes it starts on the 10th attempt, but usually on the 3rd or 4th.
There are no error codes (the check engine light doesn’t come on), and when the car starts, everything works fine.
I have tried:
- Changing the ignition coils
- Replacing the temperature sensor
- Cleaning the fuel tank and adding new fuel
- check spark plugs

For what I should look next? Have someone similar issue?

Does the fuel pump run reliably?

Does the fuel pump run reliably?

I think yes, everytime I try to start I hear noise of pumping gasoline to injector rail

I had a problem where the Immobiliser only read the Key Chip in Warm weather,

I heard a relay Click when it was going to run..

Lots of people with the same issue, i don't think someone has found a solution to this day. Filling the fuel tank above the half mark on the dashboard gives you an easier start, but still not from the first crank.

In later years, fiat started to fix the (still) persistent cold start issue by updating the ECU software - https://www.fiat500usaforum.com/forum/fiat-500l-forums/fiat-500l-issues-and-concerns/31963-fiat-500l-tsb-18-017-14-improved-engine-starting-and-performance

But, such update for the bravo, i suspect is unobtanium, so the only logical step is to reach out to a tuning company and ask if they can tune the ecu and improve cold start.
