Issue with Fiat Coupe 2.0 16V
It is very difficult to start the car, once the engine is on, it can't rev and starts loosing power.
I have completely renovated the engine, the compression is fine,
- the engagement was checked many times and is also fine
- main parts that have been changed:
Fuel Pump
Furl Regulator
Distributor
Wiring Spark
Spark
Igntion Coil
MAP sensor
IAT senor
Tmepretarure sensor (injection)
Lamba Sonda
HALL sensor on Crankshaft
Clean Injectors
i tried using 3 different ECUs and there's no change with any of them
I've tracked the installation from the ECU to each Sensor and everything is fine.

Also, I forgot to mention that the car has inlet manifold kappa turbo and the balance shafts have been removed

Hi, did you ever find the problem? I replaced the same as you but it still runs the same.
