Radio isn't catching stations.
 

I haven't driven my car since January but while it was unattended I did a few things to it. I changed the oil, put back on stock struts, remove my front bumper, and remove my airbag system(isn't connected to radio).

I finally drove it today and some reason my radio isn't getting any radio stations at all. I press the "scan" button but every station is static. Does anyone know what might be interfering with my car's radio to make it not catch any stations?
