I am trying to get a 2007.5 Silverado running. This car has twin in tank pumps with -8 line. I deleted the factory fuel pressure sensor and am using an aftermarket fuel pressure regulator and return. The truck will start and run for a few seconds and then die. Truck is also setting DTCs:
0x7EB: P0192 - Fuel Rail Pressure Sensor A Circuit Low (Pending, Current)
0x7EB: P0231 - Fuel Pump Secondary Circuit Low (Pending, Current)
I think it's not seeing fuel pressure and cutting fuel. I can't turn off the DTCs, but is there a setting in HP Tuners where I can eliminate this? Possibly another way around this issue?
