electrical problem

If there is absolutely no power, I would suggest checking your battery terminals and cables. Loose/weak terminals can wreak havoc on your car's reliability.

Also, if the terminals can be moved and adjusted without first loosening the nut on them, then you need to tighten or even replace the terminal.

So check that and let us know how it goes.

Thank you for your assistance. I checked the battery and all connections were good. I have narrowed it down to either the ignition switch relay or the fusible link on the negative side. I am going to change them out to see if it solves the problem.

If the cables are good, then the problem is likely in the ignition switch or it's relay or in one of the fusible links in the GIF image below. Keep us posted and good luck. Sounds like you have a pretty good handle on what you're doing.

The ignition switch relay did not solve the problem. Is there any way to check the fused wires without stripping or cutting them?

If there are exposed ends on them you could use a multimeter and do continuity tests on them. If the ends aren't exposed, you could try to poke a small hole in the insulation on the wire and stick the leads in.
