Hi welcome to just answers my name is***** for a poor or loose connection to the G40 Camshaft Position (CMP), located behind the cam gear on the passenger's side of the head. If the connections are clean and tight, check for good ground on the Brown/Blue wire at pin 3. Check for power at the Purple/Red wire Pin 1 (typically a 5 volt power supply but may also have near battery voltage).
If all voltage and ground checks are OK and there is no available trigger from the G40 CMP Sensor, the sensor is faulty and must be replaced. inspect the condition of the timing belt. A loose, worn or mis-aligned timing belt can cause a no start
