UVCH connection plug

Hello guys. My 2001 started rough and I ran a scan that told me injector 3 wasn’t operating. When I went to pull the valve cover I noticed the connector looks like it has an issue. The male end looks fine but as you can see one of the connections on the female end looks almost burnt up a little bit. I’m not really sure what I should do next. Any help is appreciated. Thanks

RiffRaff Diesel has Valve Cover Gaskets, Under Cover Harnesses, and the pigtail outside for the main harness. OEM.....
Maybe CNC Fab.

If the items Gasket and under harness are original it is time.

This should be what you need to fix that pigtail on your main harness.

So I can just buy that pigtail and splice it in? I was going to pull the valve cover completely off but maybe I don’t need to? Any idea what would cause this to happen to the pigtail?

High resistance from a loose connection there or a glow plug drawing too much current are both possibilities. It's not an uncommon thing to find.

Would it be a good idea to go ahead and take the cover off and test the glow plugs to make sure this doesn’t happen again? Or the injector itself somehow? I’ve never messed with the glow plugs or injectors on this thing. 268k. Stock.
