My 2013 Impala cranks but doesn't start after I fueled up with a full tank of gas in -22 Fahrenheit/-30 Celcius. I suspect it may be bad fuel so I attached a fuel pressure tester to the fuel rail pressure valve and the fuel pump runs when I turn the key to on and the pressure measures at just under 70 PSI. It doesn't continuously run the fuel pump so I removed the Vacuum/Pump relay in the fuse box and jumped the 87 and 30 pin together. However, the fuel pump doesn't run in this situation and I can hear a buzzing noise from somewhere around the valve cover/intake manifold. Does anyone know how to get the fuel pump to run so I can empty the fuel tank? Or another way to empty the fuel tank? Thank you for reading.
