Hi there newbie here,

Problem, I have a 2001 KR Supercrew with about 90,000 miles 5.4 v8 and it ran fine yesterday. Went to start it today to go to work and it turned over fine, just wouldnt fire. Any ideas?
My lack of mechanical skills and your expertise is most greatly and most humbly appreciated.

 

I'd be surprised if you find too many gear heads around here. I would recommend some of the other forums (if you haven't already). Or possibly a mechanic!

Could be any number of a million things and engines these days are at least as complicated as your home computer. Proper diagnosis beyond the obvious usually requires sophisticated test equipment.

Sounds like you might be in need of a routine checkup anyway. You don't want to be left stranded somewhere at exactly the wrong time!

 

If it's turning over but not firing and it was ' the old days ' the obvious problem is fuel supply.
However as Svermill suggests there are so many things with modern engines and systems that could cause those symptoms.

However if it were me I would still start with a fuel line check.

Hope you sort it !
