1999 Pontiac Sunfire, no power to ignition (won't start)

Switch off, other wires show zero voltage. Grounding meter to steering column mounting bolts. I took the fuse panel box that is under the hood loose to check for possible wire fell off or bad wire, ect. While jiggling the wires around, car came alive for a brief moment. Heard a click or snap sound, like a fuse popped. Checked fuses, all ok, but no power to instrument cluster again. Thinking inline fuse? But cant find the rascal if it's in there. Considering replacing fuse box. Not sure what else it could be

Ok just rechecked the wires going to the switch & ran a wire to the ground on the battery to assure I had good ground.
With ignition switch OFF & all plugs connected to switch, the 2 beg red wires show 12+volts, the little green wire shows 10.44 volts, all other wires are zero volts

With ignition switch on, the big red wires ( ignition hot) both drop to zero volts

Going to go do that now. Will tell you what I find

Ok, red wire going from battery to fuse panel under hood corroded, cleaned it up, checked voltage from battery to fuse box on every wire in the box. All of them show 12+ volts EXCEPT the small wires ( orange, purple, green, green/white stripe) they have zero voltage. Also tested every relay in box. My multi meter doesn't have a continuity tester, so hooked battery to pins 86&85 on relay, & ohm'd pins 30 & 87 to see if circuit opens. All relays clicked & ohm'd out. Son took my truck to work. So cant go after a new cable for fuse box & contact cleaner. So will have to wait till morning. But with running a heavy guage jump wire from battery to post on fuse box, still have power to switch, but when turn switch on, voltage drops to zero. Dash lights & instruments still dont come on

Also. When checking the voltage on the wires in the fuse box. They read 12+ volts ( cept the ones I mentioned) BUT they didnt instantly show 12 volts, it climbed up slowly

Yeah, gonna replace em both. But will be tomorrow. Also going to remove the copper plates in fuse box, sand them down, make them shiny & drown em in die electric grease when re-assembled. Will let you know tomorrow how it goes & thanks much for the help so far!

Replaced both battery cables, replaced wire going to fuse box, removed & cleaned contacts in fuse box. Same problem, power to switch when off, turn switch on, no power

Thinking there may be a short in one of the ign wires going to fuse box under dash, going to run a jumper wire from fuse box under hood to ignition switch & see if it powers up, if it does, replacing some wiring, if it dont. Breaking out the.45 acp & putting that car out of my misery.

Found it. Ignition wire between hood fuse box & ign switch has a short, running new wire now. Again MUCHO THANKS! If there is a rating thing on here, you get an A+!
