Good evening,

for the car in question, the symptoms are as follows:

• Engine warning light switching on and engine shutdown when 2500 rpm is exceeded.
• Possible restart after approximately one minute or more
• When the problem appears, and during restarting, the power supply to the diesel priming pump disappears (installed lamp on priming pump power supply wires), and by switching the ignition off and on several times with the key, as soon as the power supply reappears, the car restarts.
• Sometimes only engine warning light comes on with car in degraded mode with presence of power supply to priming pump, and switching off engine does not restart with lack of power supply to pump.
• If I keep the car never below 2600 rpm the problem does not occur.
• Replaced diesel pressure sensor, pressure regulator and diesel filter.
• Any tips?
• Greetings.
• Stefano
