(Pt 2) Chevy is DEAD...Shop STUMPED...After AFM DELETE?! ('20 Silverado 5.3L)
After taking the CRANK-CAM oscilloscope waveforms on this "Beached Whale" 2020 Silverado in Part 1, I got a KNOWN-GOOD waveform from the Legend John Thornton. And guess what...they MATCH PERFECTLY...within 1 degree!! So... the mystery deepens! If Cam-Crank is SPOT ON, and the engine runs fine with the CMP sensor UNPLUGGED, then WHY will it NOT build High Pressure Fuel ONLY when the CMP is PLUGGED IN?? We have to dive deeper into the operation of this GDI High Pressure Pump, specifically the Fuel Solenoid TIMING with respect to the Crank and Cam. And for that we need a KNOWN-GOOD Stock Silverado. Enjoy the GDI Rabbit Hole! Will the Final Diagnosis be correct? IVAN'S PICOSCOPE WAVEFORMS: https://drive.google.com/drive/folder... TOPDON Phoenix Plus: https://www.amazon.com/dp/B091BQNR3S?... Ivan
