2003 F150 Trouble starting
My 2003 F150 4.6L has been having trouble
starting the past couple weeks. It cranks nice and
hard and usually starts but every once in a while it
takes a couple tries (only in the mornings or after
it's been sitting for a while). Once I get it started, I
can turn it off and it will fire right back up. Fuel
pump and filter were replaced in May, timing
chains were also replaced in May (timing chain
guards broke and caused the chain to jump). Any
ideas what could cause this? I don't want it to get
worse and leave me stranded.
