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" and the Dealer are STUMPED...the truck has been off the road for nearly 3 MONTHS!! Owner is getting frustrated as well.

Let's jump right in and see why the Chevy is Cranky-no-Starty.
Looks like Fuel Pressure is NOT building in the GDI system...but WHY?
NO CODES are set!!!

Here we go....make LOTS of popcorn!
