willl this work for a 2012 chevrolet silverado lt 5.3? thanks

It looks like a 2012 did come with Active Fuel Management system. The Range will work on it. If you have further questions Range is great at answering questions.

Will this work on a gmc 2019 pickup denali 6.2 engine

Yes, it should work fine. Thank you.

Will this work on a 2019 suburban 5.3?

I believe it should, works on a 2018 5.3 silverado.

Would this work on my 92 oldsmobile?

I don’t believe Active Fuel Management was available in ‘92. So, I would say no. But check the product page on the Range website for compatibility just to be sure.
