No electrical power?

I'd have to be sure the battery has a full charge and the charging system is working ok. If the battery is down, you can't do any testing.

Use a digital multimeter across battery posts, everything off, what is the reading? 12.6 volts is the generic spec for a full charge. Leave the meter leads on the battery, have helper turn key to crank, usually the voltage shouldn't below 10 volts, much below that and the computer may not work.

Make sure the battery terminals are clean, tight, and the cables are in good condition. Check ground from battery to engine block to make sure it is tight and clean. Check main fuses under the hood in power distribution box. I am assuming that there is nothing is working.

Possibley some fuse links do you have a pic of what was smoking?

I posted a couple of wire diagrams follow the wires make sure you have power to them and check the fuse able links in the diagrams.

Also have you checked all the fuses inside and out?Thats another thing you need to check.

Your welcome anytime glad to hear you got it fixed.
