Method for starting an internal combustion engine

To start the internal combustion motor, in a vehicle, a control determines the operation where initially fuel is injected for an injection time (t1) into the cylinders according to the fuel pressure. The control monitors the pressure (p13) on the fuel before or at the start of the injection, and the control registers the fuel pressure (p13danach) at the end of or after the fuel injection. The control sets the injection time according to the two fuel pressure readings.
