I used a test light instead of the multi-meter. Do you recommend that I go back and test with the meter to get the exact voltage?

I am not getting any voltage to the fuse that goes to the ECM, dash warning lights, and gauges, but the fuse is not blown. There must be an open somewhere, and I need to find it.

How did you test the fuse. A blown fuse is not always visible. Use a meter to check voltage on both sides of the fuse.

Ok, I checked the fuses with a test light, but I will use the meter. They each should be getting 12V right?

Yes, you should have 12v on either side of the fuse with the ignition on.

I checked the voltage on each side of the fuses and found that 2 fuses only had roughly 3 volts going to them while the rest had 12.2-12.3. The fuses with the low readings are the one that control the ECM, gauges, etc...

Without a wire schematic for that car, I'm at a loss. You definitely have an issue between the ignition switch and the fuse box. If I were to take a bet, I would say possibly a bad fuse box or some build-up / corrosion somewhere inside the fusebox.

And if you get a chance, post up the exact results of each of the ignition wires and what voltage they are getting with each key position. It's a little tedious, but it will make sure that something wasn't missed in the ignition switch.

I do have a wiring diagram, but I'm not a technician so I don't really know what to look for. I try to trace the wires, but there are connectors, splits, etc... and it throws me for a loop.

As for checking the voltage of the ignition wires and taking note of them, that's something I can do in the morning.

If you can find a way to attach the diagram (either by picture, scanning, etc) it would help.
