i've been working on cars for years, and never had i had anything like this happen, i don't know where to go from here. car is an 86 iroc, manual trans. headers got hot and burned through the brake line, i knew it was too close to the header but it had been fine for years so i never thought anything of it.

today i bend a new hard line, put a new brake hose on, and bench bleed the master cylinder. tighten everything up and go to back out of the driveway and the car has no power. turn the key, nothing....i had just pulled in 2 hours before. i turn the key a few times, car finally fires back up, but my fuel pump isn't running, so it dies fairly quickly. i put the key in the off position, and the brake and choke lights stay on. I turn it back to the run position and those lights go out and the alarm starts going off, but sounds abnormal. there is no power to the fuel pump, headlights, power windows, only thing that seems to work are the gauges and the starter...

i blame the igntion switch, thinking that maybe somehow the internals got screw up or something, maybe reversed, since that is the only reason the gauges would have power when the car is switched off. changing it seems to have fixed that problem, but i still have to power to anything in the vehicle except the starter. i check all the wiring, don't see anything burned or cut, everything in the whole car seems to be ok. I'm trying to fix this for my brother, please help!

 

I'd start with making sure the main lug at the starter is clean, tight and checking the fusible links coming from it (thin wires up to the black 'capsules' on that lug). The smaller wires are the primary power wiring to the cars fuse panel.
