An arrangement and a method are provided for improving performance of a start assist system for an internal combustion engine of a vehicle comprising: a start/stop system, a primary source of electrical energy, a secondary source of electrical energy, an electrical starter motor, an engine control unit, and additional vehicle electrical loads. A start controller is arranged such that the starter motor and engine control unit are operable with power supplied from the primary source of electrical energy at an initial cold starting attempt. If reset of the engine control unit occurs during the first cold starting attempt, the start controller is arranged such that the starter motor is operable with power supplied from the primary source of electrical energy and the engine control unit is operable with power supplied from the secondary source of electrical energy for an additional cold starting attempt.
