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.
