My 92 Dak 3.9 has done the stop and start thing for two years. Well now it stopped running completely. I've replaced both the crank sensor and hall sensor and still no spark. I have noticed the fuel pump doesn't come on briefly when you turn on the key either and I cant get it to give me any code with the key on/off thing.

WHAT CAN IT BE NOW!

 

It could be the notorious power splice to the ASD and power steering pump relay, or if they are getting power the pump could be going out.

 

ASD is getting power but no spark to the plugs. I have checked the so called Power Taps and fusible links that I could find and they seem fine.

The "check engine" light doesn't come on for its bulb test when you turn on the key and I can't get the light to blink a code when I do the key on/off thing. Could that indicate the ESU is the problem?

 

The ASD may have power, but is it working and putting out power. Did you check to see if the computer is receiving power at the computer terminal?

 

I switched the ASD relay with another that I know works. So the actually answer is no. I'm not sure what comp. terminal you are referring to.

 

Then check the FAQ for service manuals and wiring diagrams to check the wires to see if it is getting power and ground. Then check the wiring diagrams and find the power wires for the computer and check to see if it is getting power. Just like said before it most likely is the power splice. Go to the FAQ in this section to read about it.

 

I've been to the FAQ section and it BLOWS big time. Cant get nothin! All it has to say is "Sorry no matches"

 

Look in the 1st gen dakota section. Where you clicked on this post. Then go a few post up. Look to the left side. Look for a GREEN ARROW. It will pointing to "FAQ"

 

Ahhh. Ok.
