(Pt 1) Chevy is DEAD...Shop STUMPED...After AFM DELETE?! ('20 Silverado 5.3L)

Pine Hollow Auto Diagnostics

A DESPERATE Shop owner called me in to diagnose this 2020 "Beached Whale" Chevy Silverado. It drove in with a failed Lifter Tick. Classic 5.3L V8 GDI. A comprehensive AFM DELETE was performed: new Camshaft, Lifters, and ECM Tuning. And now the truck is DEAD....Crank No-Start. All of the "Experts"
