Subject: '93 code 27, can't fix injectors. IP: Logged
Message: I guys, I have a '93 Dakota LE 2WD with a 318 under the hood. I can't get rid of this code 27. Here's some details...
I first got a code 27 about a month ago (the code actually showed up twice). I changed the fuel injectors with some fuel injectors I got from a 95 Crown Vic. Still got a code 27, so I changed them all again using another Crown Vic. Still got a code 27... and yes I reset the computer after both times.
Sometimes my truck runs great, other times not so great. I could smell gas, so I pulled out the spark plugs and they're all looking pretty good except for one of them has gas on it. I changed that injector again, nothing. It makes me think that the injector is getting stuck "open" and more than necessary gas is coming out. I checked the SMEC and everything in there looks good.
What's next? is it just a bad spark plug/wire? It couldn't be that simple could it?

Message: Check the wiring harness for the injector that has the problem. It is possible that the insulation has been worn off and it is shorting out. A number of people have also reported problems in the past with a variety of critters chewing on the insulation. Worth a look at any rate.

Message: I riped off the tape and traced the wire from the faulty injector back to the SMEC and the wire and all the other wires look pretty good.

Message: I too had that problem and went crazy trying to fix it - changing injectors, wiring...
The problem was my computer. I replaced it and it has run great ever since. I just wish I had bought the performance computer instead.

Message: Yeah I thought about just going out and buying the performance computer right now... seeing as it wouldn't hurt either way.
The only thing stopping me is that according to the summitracing.com page. The Mopar computer requires premium gas, I usually go for lower as I'm a broke college student.
So you think the computer will help? hopefully I can get my hands on one soon.

Message: Also, are we talking about the same computer the SMEC that's on the passenger side fender with the big electrical connector that plugs in to it?

Message: Could be a plug or wire. If the plug ain't lightin', no fuel's a burnin'. That's the easiest thing to check, I'd go there first. If they are ok, pull the fuel rail with the injectors intact. Lay some white paper underneath them and then turn the key to the on position. Check the spray pattern of the suspect injector as well as the others and see if it is dribbling fuel or spraying a nice fine mist.

Message: Check the wires and plugs all day if ya want - the code is referring to an injector (no 5). My problem was intermittant and drove me up a wall trying to fix a good injector and its wiring - my bet - its the computer.

Message: Well I ordered an ECM that should be coming in a day or two. I'm hoping this is the fix... I'm also hoping the ECM I buy isn't garbage too.

Message: Well I put in the new computer yesterday and it ran great... until this morning. I started it up and went to scrape the windshield, got back in the cab and noticed the engine light was back on. Code 27 again. What else is there to do? here's a quick list of what I've done so far:
1) change fuel filter
2) ran fuel injector cleaner
3) changed injectors (Crown Vic OEM# FOTE-D5A)
4) changed injectors again (FOTE-D5A again)
5) checked connections, changed a plug in for one of the injectors.
6) new computer
What else is left? should I maybe put the original injectors back on instead of using the Crown Vic injectors?

Message:
Check the gounded side of your injectors wiring.
Your injector no. 5 has a 2 wires. Note the color of the wire and find it at the computer. Run a new wire (outside the wiring harness)from as close to the computer as you can get to the injector (you can take a thin sewing needle and push it into the wire at the computer to actually get to the wires pin). You can do this to the grounded side also.

Message: I assume the grounded side is good. When I followed the grounded wire it went to a section of wires that were sodered together. The connection to that cluster of wires looked good. I assume that if the grounding was bad then all the other wires in that cluster would be affected too.
I will try pushing a new wire into the computer section. What about the original wire thats connected to the injector? should I remove that wire in order to insert a new one?

Message: I would cut the old wire near the injector (is this the injector plug you replaced?) - it would insure that the new wire is successfully inserted.

Message: Please help.i also have a 93 dakota 4x4 with 3.9L
Im having almost exact same problem . I keep getting
code 27..when light comes on...She acted like she
wasnt running on all cylinders , but a few times
while going down road running rough she has
straightened herself out and ran good again. but
light stayed on ..i checked and i was only getting
30psi on fuel rail at an idel so i assumed fuel pump
or filter . Replaced filter then fuel pump today .
And i got no change at all, and still only 30psi on
fuel rail. . The check engine light came on after
only 5 min of cranking her after new pump installed.
But i did finally use a long rod and listen to my
injectors to see if they were hitting and driver
side closest to cab was not making any noise . But
on passenger side middle injector i noticed the
plastic clip that locks it on was broken . i pulled
it off while she was ideling and got nom change in
idel .. but when i listened to that paticular
injetor it was ticking like it was working. Shouldnt
it of changed the idel when i disconnected that
injector , if it was working . but definatally didnt
hear anything out of the one from driverside ..Im
not that mechanically skilled . If told what the
problem is i can turn a wrench and swap a part but
not good at diagnosing ..Also i cant find anyone
with a scanner that will fit my truck anywhere
around me ..so if yall have any ideas please i need
help
