Update - 3/22/2005

The last thing I did in November 04 was to swap out the ECM (inside by
passenger kick panel)
I bought it off E-Bay - big risk. but it worked & did the same as my
original, for about a week. Fuel pump runs, runs, engine cranks,
finally pump shuts off(pressurized)engine starts. F....!!1!..
Same shit different ECM. could I have 2 identically bad ones? Same
scanner codes also!
about a week later this FP run / no start problem went away.
Its now Feb. 05 & no problems with that.
CEL still comes on after a short time. 1min - 5min. & poor throttle
response from idle(smooth) to around 2000rpm. Not noticeable when on
the road.
It passed emmision test last week( weeew!)

So its one of "those" problems. The only thing I did was to run a few
cans of sea-foam injector cleaner in gas last Oct 04. Hmmmmmmm
I've never had much faith in cleaner additives correcting an injector
problem.
But I could see using it as preventive maintance regularly during the
year. I never did that.
Ok that's that for now. Time will tell

94 Explorer limited (yes very limited)
4L v6 4WD 160K (bought new in 95)
Have used Amzoil 2X / year its intire life. No oil leaks/no oil
burning.
I think that says somthing.

Thanks again to all out in usnet land!
