Why won't my 1997 F-250 351 Winsor 8 cyl not start or will stall

Hi, Concerning your stalling or no start condition it very well could be a fuel related problem but, without performing some testing this would only be a guess. You could have a fuel pump failing, a relay failing or an electronic device failing etc. We would have to duplicate or catch the problem when it failing and perform testing. I would suggest instead of spending money on buying parts you could be spending money on having it tested to find the exact cause and if money is the issue after the testing then buy the parts and install them yourself. Sorry we can't be more precise Thanks, Jim
