Question on Stalling??? maybe fuel pump??
 

I have a 2003 Ford Explorer Sport Trac with 68,000 miles. I'm thinking
I have a fuel related problem. Idles fine and will accelerate normally
up to 3,000 rpm. After that, runs rough and won't accelerate. Let off
throttle and idles normally again. So I replaced fuel filter.....no
luck.

Now I'm thinking fuel pump.

Are there other things that I should be looking at??? No codes
flashing....nothing. Maybe a sensor???


Appreciate any ideas before going to the dealer.

SHOULD set a code.

Constipated exhaust. Does the exhaust sound unnaturally quiet? Is
there a whistle to it? You can disconnect it up front and test drive
for an internally collapsed muffler or clogged convertor. DO IT
BRIEFLY AND CARRY A FIRE EXTINGUISHER. YOU COULD BE THROWING FIRE AT
THINGS YOU SHOULDN'T BE THROWING FIRE AT!

Why not go to a good independent shop? There are tests like fuel
pressure, datastream scan etc. A good independent professional tech
will do better for you than the rookie of the week at the dealer. Of
course, I know nothing about the particular shops and dealers in your
area.

Hello there .............. I have a 2002 Ford Explorer Sport Trac doing
EXACTLY the same thing. Try to rev the motor and it chops off precisely
at 3000 RPMs. I just swapped the fuel filter - no help. Have you
figured yours out yet? I know fuel pumps and catalytic converters are
expensive and I donn't want to swap them unless I am sure.

I did notice there is a strip of discoloration in the metal around the
muffler - looks heat induced and it's only a couple inches wide all the
way around. I wonder if this points to an internally collapsed muffler?

Please let me know if you have any updates!

Thanks,
Bear

Man.... Am I a dumbass or what?????


This is going to sound really silly..........but here is what I found
out. Took it to my dealer and he explained that the engine is
"designed" to cut out at 3,000 rpm WHEN IN PARK. Basically, the
computer governs the fuel so you can't rev and damage the engine. The
truck runs fine in any gear..... I only noticed this one day when
trying to warm the engine up. I felt like a fool. Truck is just
doing what it is supposed to do.

Also, the dealer said to take it out on the highway and "open her
up"... If it cuts out, then bring it back..... Took it out and truck
jumped from 2500 rpm to 3500 in the blink of an eye. So, no
problems.......

Wow! That's good to know. Now I feel stupid too! LOL But my truck
really did/does have a problem. It would not accelerate while driving
down the road all of a sudden the other day. I was barely able to make
it back home. Also the air conditioner cut out at the same time. I'm
thinking the truck's brain box may cut out the air if there is another
problem - hoping anyways. I decided to try the cheap things first and
since it acted like a fuel filter I changed it out but I never drove
the truck afterwards. Just tried to rev it up in the driveway. That's
when I noticed the 3000 RPM clip. LOL So it may actually be fixed with
the fuel filter .............. I'll take it out on the road later and
see.

Thanks for your reply,
Barry
