Will code 2654 and code 2649 stop my car from starting

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! You've made it this far! You're almost to the finish line! Error codes P2654 and P2649 are related to issues with the variable valve timing (VVT) system, which could impact engine performance but typically shouldn't prevent the car from starting. However, if the VVT system has severe issues or if other components were affected during the engine swap, these errors could contribute to starting problems. Ensure all wiring and connections related to the VVT system are properly connected and functioning. Was the ECU replaced or reprogrammed? Is the ground connected? Retracing your steps carefully is time-consuming and frustrating, but it will point you in the right direction. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
