Be sure that any engine immobilizer system (security system) is not activated, thus preventing the car from starting. Check for the characteristic, but momentary, whirring sound from the in-tank fuel pump at key "on". If no fuel pump operation is detected at key "on", check for battery voltage at the pump wire harness at key "on". If no voltage is detected, that circuit has to be diagnosed to find the fault. If there is power to the pump, but no pump operation, the pump is probably dead. If pump operates, check fuel pressure in fuel rail. If fuel pressure is within factory specification but there is no injector operation, the injector circuit has to be traced to find the fault. If you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.
