what do they check during tech before they allow you to race?...my airbag light has been on forever...will i not pass for that?

 

you'll be fine, your car doesn't have much work done, you have nothing to worry about. Look up for the NHRA tech inspection onlie. Basically they check for things like making sure you have seat belts, your wheels are ona nd you have all lug nuts, that your battery is tied down, etc.
