I am looking for another fuse box on the car besides the one in the glove box?

Electrical problem 6 cyl Two Wheel Drive Automatic 145000 miles

i am looking for another fuse box on the car besides the one in the glove box?

its a station wagon I am looking for possible blown fuses witch would have resulted in hooking batter up backwards.

What codes am I looking for how many blinks before I find out what the problem is? If the computer is responding how good of sign is that? The car turns over but wont fire could there be a different problem?

Nothing under the hood I need to get to the computer and start checking for power. If I check the coil pack for power what color wire would I check? I have checked for power there last time and I couldn't find any but that doesn't mean I was checking right but if the computer is sleeping than what?

Ok I have power to the coil pack and the fuse panel inside the glove box what should I look for now it still wont fire

Is there any specific way to check for power at the computer I have power at the coil pack and in the fuse box but still no spark maybe it is possible for it to be something else wrong?
