Technical My car doesn’t start without engine spray

[ErDe]

Hello! I have been having problems with my Punto Evo 199 1.3 MJ Diesel.

The car won’t start without an engine start spray. If I turn it off while driving (while still moving), it starts again on itself but if I stop the car it needs the spray again.

I have tried replacing the mass air flow sensor and the pressure control valve (common rail system) but it didn’t solve the problem.

Any suggestions about what I should do?

Check the pressure of the fuel rail..

The OBD Port can read this from the motor ECU..

LOW pressure will not allow injection of fuel
