Corsa D Hot start Fix

[ruffles1986]

Hi mates. I have a Opel Corsa D. When the car is hot the car is hard to star, as VAG group cars. Also when the car is hot and i press accelerator and then depress it revolutions down near to stop engine.
Is posible fiox it on ecu?

It seems, that the engine is 1.7 diesel, does the engine rpm's fluctuate when engine is idling? If yes, check fuel pressure, if the fuel pressure is fluctuating +-more than 50-100 bar on idle, change the denso pressure regulator, which is located on the pump :)

Not fluctuate, only when i press and then depress i revs go down the engine is near to stop. And when the car i hot if i stop the engine and try to start is hard to start. I checked injectors and is fine.
