Having problems with your 2003 Ford Focus ?
Does a 1999 ford focus fuel pump from another vehicle have to be recoded to work with my car.
You might have a fuel reset button. They are usually in the glovebox. You might want to check the fuse/relay to the fuel pump as well.
Fuel pump doesn't have any coding to do. It is either the correct pump or it isn't. If the fuel pump you are using is from the same type vehicle with the same type fuel system then it should work. ow, a 1999 fuel pump probably will not work with a 2003 vehicle. They had different fuel pressure requirements and connections.
