Hello everyone,
I am new to this site and hoping that someone can help with some issues. Electrical and the Ignition switch. I have a 2001 pontiac bonneville (4 door sedan) and I am not getting any power to my Ign. switch, anything that runs on the accessorys is dead. If I pull my Ign 1 relay (under hood) and jumper it, I will get fuel pump, dash lights, power windows, radio, heater, windshield wipers ect. Does anyone know color of the 12 volt feed wire and where it goes from the Ign. switch to the power source? Any electrical diagrams would be great too! Been trying to track this for 4 days now. Thanks guys!

This?

Or this.

That looks like it, but is very blurry when I try to view it or print

How's this.

There is also a TSB on the ignition switch causing a no start condition due to plastic pieces interfering with the switch contacts. That could make it appear as if it's not getting power.

It is better to keep repair questions on the forum, so that everyone can benefit from it. Travis (sonoma_zr2) provided the electrical diagrams.

If it appears that all relays, connections, and fuses are getting power, it's possible that you could have a grounding problem. The relays are switched via ground, not via the source.

Ok, all wiring for source is ok and haven't found ANYTHING wrong with power (relays, fuses, continuity on supply wires) . So you mentioned grounds.... do you know where I might start looking for these? I see the diagrams are not showing me the grounding system. I really do appreciate the help so far!

The grounding occurs within the PCM. If you can jumper past the ignition switch and get normal action, that would still be my first suspect. The switch is separate of the lock.

I tinkered some more with this and here is what I have came up with. The 15amp fuse labeled Ign switch, is good and has power to it. If I pull the fuse, I loose interior lights and such. Ok..thats expected. Now here is where the problem comes into play. The Orange wire from bottom of fuse box (under rear seat) has no power going to the ign switch. I am assuming this is a constant power from battery and tied in with the "ignition switch" fuse. Continuity is good from bottom of connector (of the rear fuse box) to the ign switch on this orange wire. If I run a fused jumper wire (positive source) from bottom of the connector of rear fuse box, to this orange wire, I have power to the switch and dash now works. I can not see continuity, from bottom of this connector terminal to the 15 amp ign switch fuse. My guess...I should be. So, without 15 amp fuse and orange wire jumped = ign. switch working but no ctsy lights. Fuse put back in and orange wire jumped = ign. switch working and also ctsy lights (no matter what, still missing heater and radio). So.... fuse box buss blown?? Is there a way to disassemble the rear fuse box to check for any damage internal. And if so, how does it come apart?
