Start motor cranking

/ 9-3 (9400) / 2000 / 2. Engine / Motronic 2.10.3 (B204i) / Technical description / Start motor cranking

As soon as the start motor starts rotating and the control module receives pulses from the crankshaft position sensor, the fuel pump relay is activated and all the valves open and remain open depending on the temperature. This will only occur once (first injection) and only if it is colder than 20°C (68°F)

After the first fuel injection the system will return to a sequential injection.

In connection with cold starts, up to 0°C (32°F), injection occurs with open inlet valves.
