One of two things can cause this problem to occur. First is one of the injectors is shorted out in which case you should unplug all injectors and then replace the fuse, plug the injectors one at a time until the fuse blows then replace that injector.
Or you have a short in the wiring which is touching ground somewhere, insect the wiring harness closely to see if you can find the damage.
Here is some wiring diagrams (below) so you can do some testing.
Please run some tests and get back to us so we can continue helping you.
