The fuel injector fuse keeps blowing and causing the car to not start. What could be causing the fuse to keep blowing and where do I start to fix the problem?

You have short circuit between the fuse and the fuel pump relay or between the fuel pump relay and injector

Where would I even begin to look for the short? If my short circuit was between my fuel injection fuse and the relay. The car would not start would it?

I would unplug all injectors and replace the fuse then turn the engine over to see if the fuse blows if not plug the injectors in one at time until the fuse blows, that will be the bad injector.

Here is a guide to help you see what I am talking about:
