Embodiments herein relate to an arrangement and a method for improving the performance of a start assist system for an internal combustion engine (ICE) of a vehicle comprising: a start/stop system, a primary source of electrical energy (V1); a secondary source of electrical energy (V2); an electrical starter motor (S); an engine control unit (ECU); and additional vehicle electrical loads. A start controller (SC) is arranged such that the starter motor (S) and engine control unit (ECU) are operable with power supplied from the primary source of electrical energy (V1) at an initial cold starting attempt. If reset of the engine control unit (ECU) occurs during the first cold starting attempt, the start controller (SC) is arranged such that the starter motor (S) is operable with power supplied from the primary source of electrical energy (V1) and the engine control unit (ECU) is operable with power supplied from the secondary source of electrical energy (V2) for an additional cold starting attempt.
