Q: why is my car chugs and dies after a half tank of gas

asked by on

Car chugs and dies after a half tank of gas , I have changed fuel filter already last week

My car has 186500 miles.
My car has an automatic transmission.

The fuel pump may be starting to go bad, when you get below half a tank, the pump does not submerge in fuel as much to keep it cool and it will seize up and stall the motor. You will need to replace the pump and check inside the bottom of the tank for small metal bits that almost look like shiny sand. This all has to be cleaned out of the tank or it will ruin the new pump.
