Electrical issues, yay!

2004 V8, no issues like this before today. Went to start the car and there was no power when I moved from ACC to start.

At first there was no start chime but the lights, clock + mpg + temp orange bar were lit. When I moved it to start there were no lights on the dash except the red battery if I held the key there. I checked battery terminals; all good. Then I looked at fuses and tried wiggling plus pushing down on them (wasn’t sure which one to pull to check). When I tried again, the start chime plus more dash lights came on (trac, vsc,…ones with normal start) but when I moved the key to start there was a buzzing sound and the dash lights slowly went away.

This was at the neighborhood park and was with my 2 year old so couldn’t stick around to diagnose anymore. Plan is to go back in the morning with a multimeter to check the battery first.

That said, since “more” power came after I pushed on the fuses, I’m wondering if it’s not a battery issue. Maybe a bad fuse or a relay that went bad? The only other thing I could think of was when I tried the very first start, I accidentally turned the key real fast all the way through to start. Not sure if this could’ve done something.

Any thoughts? Anyone have a similar experience or can point me to which fuses or relays may cause this? I’d hopefully like to bring some fuses with me when I go check it tomorrow. If it’s one of the cube relays, it’s going to get a bit tricky to decide which one to buy and bring a spare.
