A code of po146 is o2 sensor circuit-#2 post-converter sensor,left bank. Look for any broke wires going to the O2 on the left side facing the truck.

    Facing the front of the truck? Why not just say driver side or passenger side?

Chevy wont start

sounds like seprate issues check for fuel pressure, and spark. the code refers to a poss bad o2 sensor wich would be a seprate issue since o2sensors typically wont keep it from starting, just use alot of gas. good luck

My 1999 chevy silverado started lagging down then backfiring

There are to many things to look for that cause the symptoms you described. Best thing to do is get it scanned for a DTC code, that's why your check engine light is on. Auto Zone scan's for free and most auto shop's now scan for around $10.00 to $15.00 since almost every shop has a scanner and want the business.
The scan is going to give you a miss fire code with other codes to why such as to the left or right side banks running lean or both running lean and may be a transmission code to why it shifted hard.
Good luck and keep me posted, as long as there is a engine management problem the transmission may not shift in to it's 4th gear and OD may not activate so take care not to burn out the transmission.

99 Chevy truck check engine light running lean on fuel

Sounds like a vacuum leak. try spraying carburetor cleaner or starter fluid around vacuum lines and intake while engine is running if you have a leak engine will speed up when cleaner hits leak.
