You should find a video showing how to test the fuses with that multimeter you bought.

Could my code have anything to do with this (12 Battery input to PCM disconnected during last 50 key starts.)???

Or the vacuum wire?

Next steps please...

Now turn ignition key to run position and ground black lead to battery negative/metal then use red probe and check fuses for power meter should move just like it did when connected to battery . Do main fuse box under hood first .
