There are a few reasons why your car may not start after having the head redone. One possibility is that the timing belt was not installed correctly. If the timing belt is off by even one tooth, it can prevent the engine from starting. Another possibility is that there is a problem with the fuel injection system. If the fuel injectors are not working properly, the engine will not be able to get the fuel it needs to start. Finally, there could be a problem with the ignition system. If the spark plugs are not firing properly, the engine will not be able to start.
If you are not sure what the problem is, it is best to take your car to a mechanic to have it diagnosed. A mechanic will be able to identify the problem and make the necessary repairs.
