My 351 FI windsor has problems

I have a 1991 Ford F 350 witha 351 Windsor. When I bought the truck it drove fine, but now every once in awhile it will act up, sputter, backfire, and then it will die. But if I turn the truck off, let it sit for a while, then start it back up, it drives fine. What's the deal?

Sounds like the fuel pump. Get it pressure checked, and if you change it, do the relay too.

  • Shifting problems and intake problems? I drive a 1997 ford ranger with a 2.3l automatic. I have recently experienced a hard shifting in my truck even when I'm not on the gas it has problems shifting. And I cleaned my air filter and filter hose that goes to my throttle body and there was transmission fluid in the hose. What can be causing this and how can I fix it or how much will it cost roughly?
  • In what vehicle was the Ford 351 Windsor 4-Barrel put in? I got a Ford 351 Windsor 4-Barrel in my 1966 Ford Galaxie but I don't know what vehicle it was taken from lol.
  • Do 164 tooth flex plates interchange between 1977 351 Windsor and 400 Ford engines? I know the bolt patterns are the same and balance weghts changed on the 302 in 1981 to 50 oz from the 28.2 and that both Windsor and Clevelands used the 28.2 oz. What I want to know is are the dimensions the same from the flange surface of the crankshaft mount to the bolt mount for the torque converter and is the balance weight located in the same place on the flex plate relative to the bolt pattern.
  • Windsor 5.4L built in 2002? I have a 2002 ford f150 Harley davidson edition pickup. The specs state it having the triton 5.4l v8 supercharged sohc engine. When I look at the drivers side valve cover the sticker says Windsor 5.4l built in 2002. Should the Windsor engine be in this pickup? Is triton the same as Windsor? N
