Hey, my car has a cold start issue, i've changed too many things and stil having the problem, i changed the spark plugs, spark cables , battery, injectors, belt distribution, filters ( fuel, oil, air), starter, butterfly valve i think thats it and already did a hole on fuel tank cap becouse it had vacum. Thanks

Presumably it starts when not cold?

This suggests a sensor might be mis-reading at lower temps...

Yes, this happands when i start the car on the next day or even when im not using for like 10 hrs
What is that sensor?

Sounds like the coolant temperature sensor to me: https://rimmerbros.com/Item--i-MEK100061

If the sensor has failed, the ECU uses a default setting that will allow the car to run without overfuelling, but it will not enrich (choke) enough to start from cold.

Didn't know the ECU of 99 had that impact

I've changed the sensor and still the same problem..
