2015 Chevy Silverado 150k, Gwatney DOD Delete kit. Won't start. Died on the road while scanning with HP Tuners. No codes.
Truck will fire but not start. Replaced Secondary Fuel Pump as Scanner show it never turned on. Tested 80lbs static after replacement. Secondary, in tank pump frame was in 4 pieces. Still no start. Replaced Primary Fuel Pump as it's quite loud since DOD kit, still no start. Scan says everything is working but Secondary never comes on except for Prime. I'm leaning toward the Fuel Pump Controller or the Fuel Pressure sensor associated with it. I've tried running all the diagnostics I can find, but I'm out of ideas. Here is the latest scan from today. The Engine does fire and it will try to run when you spray a little gas or carb cleaner.
Any information is very appreciated. Fuel 5.hpl
