Start problem

Hi Greg
What i have to do to solve this problem?

Are you saying that this hot starting problem appeared only *after* you removed the fuel rail and injectors?
If so, I'd go back to areas you were working in and look for any wiring or connectors that might have been disturbed.

The system is designed to provide a rich mixture when the engine is cold. Cold engines love the rich mixture; warmed-up engines hate it ! So, if the control system is faulty and giving a constant rich mixture then the engine would start fine when cold but be difficult when warm. I think Greg was thinking along these lines when he mentioned putting the throttle right to the floor, as doing so clears a flooding condition.
Most often a problem of this nature is caused by a faulty coolant temperature sensor.

One possibility, of many, is a mixture control problem.

Like you say i think is fuel evaporating on injectors rail but why?
What do you think i have to do?

Looks like item #9 in the illustration...located on the thermostat housing

Personally I don't think fuel evaporation is likely to be an issue after just 20 minutes of driving. I'd think that would occur only after long drives and/or unusually hot conditions. Just my opinion.
