I haven't heard of a pump going out on a 200. Same engine as a Tundra? Have not replaced one of those yet...Original blinking lights were from speed sensor harness.
They could not get any power from the fuel pump. There are 6 fuel pumps for the LC in the US. It will take 5 days to get it. Part is 800.
Have had several GM products that had been run out or low enough times and the pump would not work. Seems like our luck runs when the pump dies its atleast 3/4 full
