Thanks for your timely response, Kyle. My answers follow:
>DAMN! Where did you get a fuel pump for $78!! When I replaced mine,
>NAPA had the cheapest in my area at $130.
Got my fuel pump at Bennett Auto Supply in Jupiter, Florida. Only place
that had it, too. Everywhere else I called said it was a "dealer only"
item! ($150 at the dealer)!
>On my 93, the filter is against the frame rail, not in the tank.
Although everyone I asked said the filter was on the frame (I even
bought one for $15 that another auto parts place said would fit), I've
been all over (and under) that truck and there ISN'T one! Instead, its
in the tank along with everything else (fuel module). Fortunately, the
fuel pump came with replacement primary and secondary fuel filters,
short piece of hose, connector and clamp. So used those, too.
>I was also told to turn the key over a couple of times(but dont >start
it) to build up fuel pressure.
Yep, tried that, too.
>Are you sure you did everything ok?
I think so. Took great care to replace everything in exactly the same
place/orientation per the instructions (BTW, what is the "clock" the
instructions refer to re: fuel pump? I put everything back as before,
but don't have a clue what that's about. Is there a timer to regulate
flow, or does the pump provide steady flow?).
>Hmmmm, not sure why your Dak is running this way......did you reset
>your computer after the pump change? Did you disconnect the battery
>before replacing the pump?
Yep (disconnecting the battery resets the computer, right)? One reason I
wanted to take it around the block. The battery has been disconnected a
few times before, but never ran this rough while the computer relearns.
>Maybe try running a water remover through the fuel system? How about >a
good fuel system cleaner?
I put STP injector cleaner in and let it run at idle for 15-20 minutes,
couldn't tell any difference. Good suggestion, tho'.
>Maybe an injector is clogged??
Gee, I hope not! But that's what I'm starting to think. Any way to check
without taking the injector(s) out?
In a message dated 99-02-05 18:51:40 EST, you write:
<< My 94 3.9L MPI Dakota Sport stalled on a busy hiway. After replacing
the fuel filter in the fuel tank(!), it still isn't running right...but
still a big improvement over not running at all. It is hard to start,
but idles okay. But give it any gas and the engine wants to die! Both
the instructions with the replacement fuel pump ($78) and the repair
book both sound as if it should run properly after reassembly without
any special start-up techniques (i.e., bleeding the fuel line, etc.). Am
I missing something, or do I have another problem? Any suggestions will
be most appreciated! >>
