94 z28 won't turn anything on with key

last month i had a fan short circuit and it obviously burned up some wiring on my steering column cause i can put the key in and turn it to try and start it and nothing will happen i have traced a pink wire that runs down the column and have put a toggle switch on it it's the only way to turn fuel pump on and everything. the key will not turn anything on but the radio and make it so i can use the power windows that's it. but with the toggle in the on position and key in i can start car any suggestions on how to be rid of toggle switch. i have put new fan motor on and for one week i didn't have to use the toggle the key worked properly

See if there's anything in Shoebox's writeup on the ignition switch that helps:

There are also some other schematics on my site. Unless you had something out of the ordinary wired up, no fan short circuit should have cause any wiring damage in the column.

I actually sounds like the fusible links...in rare cases one melting one can take out a good one nearby.

The fusible links are located on the passenger inner fender and attach to the (+) terminal that's covered by the red cap.

Take a look at SHBOX's page: http://shbox.com/1/battery_cable_routing1.jpg THose small wires attached to item 14 are the fusible links.

Good luck!

so tried everything and nothing really came of it but on the first link given on the last picture the red wire with blue connector that's how my connector looked after the fan shorted out and is the wire that i had to put toggle on. the fans were also straight wired to the fuse block under hood the a/c fuse any suggestions from here

Sounds like your custom fan wiring is pulling too much current from where it is not supposed to. The factory fan circuits use relays to keep from doing that. I think I would return the fans to stock wiring, if I were you. Schematics on my site show the factory wiring.

Hard to decipher.... but I think you are saying the coolant temp sensor in the driver's side head is missing - hope they put a plug in the hole. No, it doesn't "control when they come on". The sensor in the head is only for the dash gauge. Any auto parts store can sell you a single-wire coolant temp sensor replacement that will fit and work.

The sensor in the water pump tells the PCM the coolant temp. The PCM controls the fans based on this temp.
