1991 Dodge Dakota wont start

Hi:
When the vehicle doesn't start, are you getting spark and fuel, or does one of them shut down?

Check the ECM wiring to make sure everything it tight. IT sounds like the is a wiring problem. If I recall, on the passanger side inner fender there is a huge wiring block. Within the wiring harness, there are several splices that chrysler made in the wiring. Open the harness about 18 inches and and check the splices for corrosion. For some reason (and I don't have the schematic in front of me) I remember a white wire with a red runner causing this problem. The splice would corrode and the truck wouldn't start.

Let me know what you find.

Are you able to pull a code?

Ken

I don't know what to say. I really feel it has something to do with the splice that Chrysler put in the wiring. Let me look into it and then you will know exactly what to look for. It's been some time since I had the problem. But I remember dealing with a white wire from the distribution center on the passanger side inner fender. I believe it ran to the computer (ECM) and as a result of corrosion on the splice, I couldn't get spark or fuel.

I will look into it for you. It's driving me nut now.

Ken:
I tried looking at TSB's, recalls. Here is what I want you to try if the truck doesn't start again. The power distribution center that has all of the small wires coming out of it is going to be the target. I believe in a 91 it's located on the pass side inner fender under the hood. It will be a black box with what appears to be hundreds of wires going into a wiring harness.

If the truck doesn't start again, carefully cut open the harness. I believe within the first 12 to 18 inches you will find wires spliced together. If they are green and corroded, cut them apart and resolder it. Any corroded splices need to be redone. Just make sure to protect your work with a quality electrical tape. Then, retape the wiring harness where you opened it to protect the wires in it.

I recommend doing this before it lets you down again. I'm confident your problem lies there.

Please let me know if this helps.
