Answer
There is a short circuit that connects to the efi fuse, check the injector wiring harness, check there are quite a few things connected to this fuse including the fuel pump, wiring for the O2 sensors and efi relay, it's going to be a little difficult to find, try disconnecting some engine wiring connectors and see if the fuse stops blowing, it could even be the ignition switch, I'm kind of busy right now and won't be able to get back for a few hours until this afternoon, I'll see if I can come up with any other suggestions. Try disconnecting the fuel pump and see what happens.
