We have replaced the fuel pump. And the car is still cutting off and it wont start. It ran for about 2 days after we changed the fuel pump. What could be wrong? We put it on the machine to see what was wrong and it was showing the oxygen senser will that make it cut off?

The O2 sensor would not cause a non starting condition unless it has caused a short circuit resulting in blown fuses.

You need to find out what is missing causing the non starting. Check out the link below for more information.
