How to disable fuel pump 07 NBS
I need to know if it is possible to disable the fuel pump in a 2007 NBS with a 5.3 AFM. I have already pulled the fuel pump fuse and relay, truck still runs and has correct fuel pressure.
But is the fuel pump still running...if so you didn't pull the right fuses and relays.. There can be enough fuel in the line to keep the vehicle running for several minutes at idle if the pump is off...try revving the engine once the fuse is pulled...
