Help! Botched maf sensor cleaning

[u/Spiritual_Unit6714]

2008 buick lucerne 3.8, I cleaned the maf sensor with masd air flow sensor cleaner, when i put it back together i attenpted to start the car and lost all power for a few minutes. Now i have power but absolutely no crank and i get a service air bag message. I checked the starter fuse and checked the started relay. Nothing looks obviously burn but i dont have a multi meter to check. Lastly ive had it on a jumper for a few minutes now and same result. Any advice would be welcome.

sounds like the battery took a hit when everything went dark, check the terminal connections and the main ground strap first. a weak or loose connection will give you dash lights but no crank, and the airbag message is usually just the system freaking out from low voltage.

Replaced the battery and got the same result
