Engine Mechanical problem
2003 Ford F150 6 cyl Two Wheel Drive Automatic 93094. Miles

my o3 f-150 starts for a second then it cuts off like its out of fuel. But its got over a 1/4 tank. It'll do this over and over. Then I smell gas like its flooded. I hold gas peddle down all the way to the floor and it starts runs like its flooded or like its jumped time. Idels real ruff and putts and spudders. Then all og a sudden it takes off and runs normal. Once it acted like I was out of gas while driving but never cut off all the way just like it was running out of gas but had plenty. I put new plugs in and it did it again. Today while driving it just started acting like it was cutting off then it ran for a while HELP

Have you checked to make sure it is getting a good spark?

Yes, and it does. I even replaced plugs just to be safe to.

If you smell gas, either the spark isn't hot enough to ignite it, or there is a timing or compression issue. Is the spark a hot blue snaping spark? Also, I question if it has spark when in the start position and then loses it when in the run position. Does it die when you place it in the run position?
