Running like #^#*
Ok so I have a 1991 bronco with the 5.8. It ran perfectly for ever. New fuel pump filter regulator. All of a sudden it died on me. Now when it's cold it still runs fine but when it gets warm it just quits. It get worse the more I try to start it. But if I wait till the next morning it runs fine again until it gets warm.
I ran codes and it came up with : 40 46. 21.
Heeeeeeelp
