92 should be pre-magnum engine. A 93 Dakota will be a Magnum, so I don't think you have the right years above. A 93 PCM will work in a 94 and 95 Dakota. 96 is OBDII, so it is a different syustem in itself.

An automatic PCM will work fine in a 5 speed truck. Only the tach light will be off, which I never found it to be that useful in my stock 5 speed anyways. Also, a RAM ECM is running the same engine as the Dakota, therefore it should also work without a problem. Since both are manual I believe you said, you will have no problems.

Like OUtshined said, you can run the two extra wires or I see no reason why the Ram harness shouldn't work, it is the same engine and should be the same ECM. You already have a manual trans so you don't have to worry about the grounding for P/N switch. If you did ever change an auto to a manual, you just need to change the plugs that activate the P/N switch from the automatic trans shifter to the clutch pedal. It is pre-wired essentially. It is a green connector under the dash near your clutch pedal. Yellow wire I believe.

92 Was the first year for the Magnums, my first 318 came out of a 92.

The Ram harness is different - the PDC on the one I looked at was in a different spot. The PCM connectors are the same. I ran a 94-95 Mopar 5.9 computer in my truck. The only issue it gave me was it tripped a code for tranny temp too low. My truck does not have a tranny temp sensor to begin with, so I assume that was specific to the 5.9 powered Rams.

If you are desperate I am parting out my 92. Have the engine harness already pulled. Also have the MP PCM.

I have a 95 ram pcm. As for the harness, my plan is to use the injector wiring from the '97 and use my harness. Does anyone have the diagram to so this?

Hi, I have a 1994 Dodge dakota club cab, 2 wheel drive, 5 speed, and it had a v6 in it. I took the v6 out and put a 318 v8 in it. The v8 came from a 1996 or 1997 jeep grand cherokee and I put a computer in it from a 1997 I believe,.. I will check that later.. a 1997 Dodge full size, 2 wheel drive 5 speed. I kept the original v6 wiring harness and added 2 wires for the injectors with no problem at all. I got the extra wires from a wrecking yard. I had to use a oil pan from a v8 dakota as they are different because of the jeep being a 4x4. I also had to get a y pipe for a full size and cut the end off of it to match it to the existing exhaust system,... outside of that I didn't have too much problems with it,... oh I almost forgot,... the other thing I had to do is get a flywheel and clutch for a full size truck to make it work with the tranny that was in the dakota. That was about all that had to be done to make it work.

I hope that this was a little bit of help to you. I am going to get some pics of it up soon.

Paul

Check on the year of that computer. I'm betting it had to be a 95 or older. 96 and newer were totally different wiring harnesses and computers as they went from OBD1 to OBD2 in 96.

two second fuel pump activation is normal when you turn key on...

how did you check the coil, the pick-up and other items? How do you know they ar OK? Did you get specifications and use proper testing equipment to diagnose these items?

No spark has nothing to do with fuel pump or fuses

Without using a scanner to check for data, my first "guess" would be crank sensor....
