New to your forums but have been looking them over and have found some good information, just not quite what I am looking for.

I have 02 Dakota Sport with the 3.9L with 145K. I am looking to replace the oil seals on the intake and exhaust valves. That portion I am not to concerned about as I have the tools and the seals. What I can't seem to figure out is how the electrical connectors come apart on the fuel rail. There is some sort of locking device that slides up and down and it exposes the clip when pushed down. Yet the plug won't budge and even tried compressing the clip. Ideas?

Any DIY threads on the above would be most helpful. As they say a picture is worth a thousand words.

Thanks
