A method for starting a motor vehicle engine includes measuring the profile of a rotational speed of an engine shaft of the motor vehicle engine. An estimated rotation speed of the engine shaft is determined that is expected to be present after one working cycle of the next cylinder to be fired. The estimated rotational speed is compared with a resonant rotational speed range of a vibration damper. Where the vibration damper is configured as a dual-mass flywheel and resonant vibrations occur in the vibration damper within the resonant rotational speed range. If the estimated rotational speed is within the resonant rotational speed range, at least one of introduction parameters for the introduction of a fluid to be introduced into the cylinder or an ignition time of the cylinder is changed so as to change the estimated rotational speed to be outside the resonant rotational speed range.
