Jeep Wagoneer Stumbling Problem
 

Ok so heres whats going on...
I have an 87 4.0 Wagoneer. It has been sitting outside unused for about
a year. I decided to got it out to take a spin in it yesterday, and
noticed that it will not rev over about 2,500 RPM. It almost instantly
dies. It will also stumble and sputter when I try to accelerate
moderately hard. It seems to me as though it's starving for gas... thus
leading me to believe the fuel pump has taken a dump. Are my
assumptions correct? Or is something else causing the problem? Thanks!
Gary

Is the fuel a year old as well? I would start with a new fuel filter
because that is easier and cheaper and go from there. Seems like fuel pumps
either work or they don't work, I have never had one semi work.

Hi Gary,
I would guess you also need a carburetor kit, too. Usually over a
year period the gasoline will evaporate, drying the accelerator pump
plunger, and shrinking the gaskets, causing them to leak between
galleys, plus a little corrosion usually forms clogging the jets. And
was the bad pump the reason it was parked in the first place?

Well, this isn't the carburated version... I went out and bought a fuel
filter today and it made a considerable difference. It seemed better,
but it still has a flat spot. It seems like it gets better and it gets
worse. Any ideas on that? Haha.
Thanks,
Gary

And no the supposidly bad fuel pump was not the reason it was parked in
the first place. It was a bad starter.
