 Subject: 2000 Dodge Dakota Computer issue
IP: Logged
Message:
Our 2000 Dodge Dakota V8 4.7 all of a sudden stalled while my husband was driving it to work. We haven't been able to get it to start since. Two separate repair shops said that the computer is the problem, so we ordered a replacement computer specifically programmed to our truck. When we installed it the truck still wouldn't start. We are currently working with the place we got the computer from to see if there was a problem with the computer they sent us, but I am worried it might have something to do with the connections to the computer. One of the connections appears to be producing some kind of liquid. Whenever we plug it into a computer (either the new one or the old one) when we unplug it, there is and oil like liquid all over the area it plugged into. We cleaned both the computer and the connection, but the fluid reappears when I reconnect it and try to start the vehicle. Does anybody know what might cause this and how to fix it? Thank you in advance for any advice.

The oil is most likely coming from your power
steering pressure switch. They are known to fail
and when they do they can force wire up the wiring
harness and into the computer (PCM) connectors.
It can also get down into the O2 sensors.
Before you do anything else, try this. With the
truck NOT running, turn the key to ON (don't start
the truck). Then turn it back OFF, then ON again,
back OFF, and this time leave it in ON.
Codes will display in the odometer window. It
will say P DONE when complete. The PCM even tests
itself.

AandPDan I just tried the on and off thing but all the odometer says is "No buS". It doesn't seem to be doing anything. Is there a certain amount of time I should expect to leave the car on? Am I possibly doing something wrong?
Also, if I fix the power steering pressure switch will it possibly fix the problem, or is there likely a lot of damage that needs to be repaired if that is what's causing the liquid? Thank you for your help!

No bus, most likely the crankshaft sensor. Clean computer plug with electrical contact cleaner and let dry.
A bad or dirty crankshaft sensor will show a no bus and the truck will not start.
