4.0L auto 4X4 Eddie Bauer
I use this truck for plowing the driveway. Its got a lot of clicks and
rust.
A couple of weeks ago I noticed my fuel filter was leaking, truck ran fine
though.
Next day, it was real cold and I tried to start it. It wouldnt start but
cranked ok.
I assumed it was the filter and installed a new one. Still no start.
Ckecked
spark. Spark ok.
Checked fuel pressure, shows pressure at the test port but will not hold.
ie
when I turn key ahead, fuel pump
engages for a couuple of seconds, immediately check pressure (only by
depressing tip of Schrader valve) and I get
a dribble of fuel. If I depress valve and have someone turn key ahead,
there
is plenty of flow.
seems like pressure is bleeding off through one or more of the injectors.
It
finds its way to the
basepan as the oil level rose dramatically. I drained and replaced the oil
and had it running one day
but next day, same thing. Fuel is in the base again. At least a quart.
This
is from repeated attempts at starting.
I've checked fuel pressure regulator for leaky diaphragm, its good.
One other thing of note: the first time this occurred, it was cold enough
to
"slush"ify the antifreeze.
This thing is driving me crazy. If this was an old car with a distibutor,
it
would sound to me like the dist
was off 180 degrees. It pops and bangs and spits and backfires while
trying
to start.
Is it possible that even though there is spark, the ign module is not
timing
the spark properly?
Any suggestions welcome.
Thanks Justin
