2007 f150 sometimes won't start
sometimes my truck starts first try. Other times it cranks but won't start. it's
not the fuel pump. it's not the fuel pump module. both have been replaced.
you never know when the problem will happen. Seems to be getting
worse.Very intermittent. any suggestions on what the problem could be. My
mechanic is stumped and his approach seems to be keep replacing good
parts with new parts.
