My 98 F150 4.4L v6 has a delayed start. The time of the delay depends on
the temperature of the weather. When it's 80F or higher and I turn the key
to on, I can hear the FP hum for about 6 seconds. Then the check engine
light blinks one time, very fast. The blink is so fast, you have to be looking
right at it or you miss the blink. Once it blinks, the truck starts perfect. As
the temp. drops, the waiting time for the prime to complete takes longer.
When it's 30F or lower, I need to turn the key on and wait for up to 20
minutes before the hum stops, CE light blinks, and the truck will start. Once
it starts, the truck runs perfect, whether sitting in idle, or stomping on the
gas peddle. Before the engine light blinks, it's a crank but no start. Out of
the hundred or so "crank no start" situations I've read online, I haven't read
any of them that say anything about an extended prime time that varies
with temperature so I'm hoping by asking, someone will have experienced
this and can shorten my trouble shooting experience. As a footnote, I
bought the truck two years ago from the family of an old man that had died.
The truck had 9k miles on it when I bought it so it had done a lot of sitting
around. I now have 30k on it. The problem has existed since I bought it, but
has gone from a 5 minute wait at 30F to a 20 minute wait. The truck has a
recall on it due to corroding fuel tank straps and will be going to a dealer for
that work in a week. They said they will charge $99 for a diagnosis. After
hearing stories about dealers even screwing FP problems up and charging
k $ plus to replace them and it not being the problem, I would like to check
everything else it could be, leaving FP replacement as the only thing it
could be when I take it there. So can anyone suggest where I should begin
my trouble shooting?
