Fuel injection wiring problem with 89 cherokee 4.0L
Hello All,
I just recently bought the above mentioned vehicle from a friend with
the wiring problem made clear at time of purchase. The jeep runs fine
99% of the time but every once in a while I need to jiggle one of the
wires that connects to one of the injectors. The injector wire in
question had been wrapped with electrical tape by the previous owner.
The only time this problem comes into play is when starting it, once
you're up and running it's fine. My question is what would be the best
way to fix this? Is there a sub harness for the fuel injection, and if
so how much should I expect to pay? I got a really good deal on this
jeep so I'm not afraid to spend a few bux to make it right. Any info
will be greatly appreciated.
Josh

No such subharness that isn't $$$. I'd take the tape off and find
out what is there. It might be the last person just twisted wires
together and taped them. (a bad repair) If you need a new connector
NAPA should have them.
If it's just a broken wire and connector they can be repaired if your
somewhat comfy with a soldering iron.

The connector can be dissasembled but it can be tricky. Redoing the
female connector takes patience and a bit of luck but it can be done.

Feel I should point out the heat shring tubing goes on
BEFORE you solder the connection. But you would have
figured that out in due course. :)

Re: Fuel injection wiring problem with 89 cherokee 4.0L
I've read numerous times and tend to believe (based on my own personal
experience) that it is best to not solder splices and connections that are
subject to the vibrations of an engine/vehicle. The solder creates a ridgid
point in the wire and increases the chance of it fracturing next to the
solder instead of flexing. As well, the heat applied to the wire may be
causing it to become more brittle. Apparently that's why even the most
sensitive and critical automotive and marine connections are in crimped
from the factory and you seldom see a soldered factory joint. I have
actually seen wires broken next to a soldered joint. Don't flame this, just
passing on what I'd been told/read.
