ABSTRACT:
In a method and a device for operating an internal combustion engine with a fuel pump, which on the drive side is coupled with a camshaft or a crankshaft, and a fuel accumulator, which is supplied by the fuel pump and to which a pressure sensor is assigned for sensing the pressure in the fuel accumulator, to each cycle of the internal combustion engine a first and a second crankshaft rotation (CRK_R1, CRK_R2) are assigned. Depending on a signal sequence (P_F_S) of the sensed pressure in the fuel accumulator which is characteristic of the respective crankshaft rotation it is ascertained whether the crankshaft is in its first or second rotation (CRK_R1, CRK_R2).
