what fuse keeps blowing? does it have anything written by the fuse or a fuse number? What fuse box? Inside the passenger compartment or in the engine compartment?

if it's the 30A fuel injector fuse, it powers up the pcm power relay and the fuel pump relay and goes to the alternator.

does it blow right away or does it take some time? If it blows right away, you have to look for a short to ground in the circuits. If it blows after you drive for a while you may have to separate the circuits and see if you can narrow down what circuit is the problem.

it's going to be tough to find if it takes a while to blow the fuse. You will need something that can measure the amp draw on the different circuits while the car is driven and see how much the draw is. Try looking at the wire harness for anywhere it might rub on the engine or the body and rub through. Wiggle the harness to see if you can make it blow the fuse.

a direct short would be easier to find. They make tools that send a tone through the circuit and you can follow the wiring until the signal stops and that's where you look for the short.
