I assume you know where the fuse box is on the pass side wheel well, right? Well, with an ohm meter you can start testing to see what fuses in there have continuity and which ones don't. On my meter, there's a function for testing with a beeper. It will beep if this fuse is still good. Otherwise, it will show zero on the meter. If it's bad, it will not change and show a one or infinite....no continuity. The EFI fuse should be a 15 amp fuse. The headlight fuses and all are in there, but I do believe stereo fuses and the like are behind the kickpanel on the driver's side of the cab interior. Test the fuses under there the same way.
I suppose you really oughtta test the main fusible link first, though.

You'll see it when you look in there. It's the first 30amp fuse in the line of fuses.

Yes. The fuse is about $3 at Autozone, and to replace it, you have to:
1) (After disconnecting the battery) take off the 2 bolts holding the under-hood fuse block down. The fuse block is on the passenger side fender in the engine bay.
2) take off the bottom cover on the fuse block, via 2 clips on one side.
3) Press on the clip where the fuse hooks in, and push the fuse down. It will come out the bottom.
4) Undo the 3 screws, remove the wires. I recommend using a nut driver or socket to take the screws off, they strip extremely easily. There is one large screw, a 10mm, and two smaller ones, 8mm or 6mm, I don't remember.
5) Hook the new fuse up, and screw the wires back onto it, and push it back up into the fuse block. Installation is the reverse of removal
.
If it blows again, you have some problems somewhere. Probably an underhood main wire shorting to ground.
I recommend taking the old fuse out and matching it up at the parts store. There are several different ones. You want the one that looks like this:
1) (After disconnecting the battery) take off the 2 bolts holding the under-hood fuse block down. The fuse block is on the passenger side fender in the engine bay.
2) take off the bottom cover on the fuse block, via 2 clips on one side.
