ajohnson928 Posted May 18, 2014 Share Posted May 18, 2014 Between the relay and whatever the white block is there is something missing. I've seen in on other people's MJs & XJs and I know it has a vacuum connection. Anyone want to fill me in on what it's called and what it does? The truck runs fine without it but if it could run better... Link to comment Share on other sites More sharing options...
Co.Jeep.Manche401 Posted May 18, 2014 Share Posted May 18, 2014 I might be wrong depending on your year but mine has the EGR solenoid there. Here's a pic. Link to comment Share on other sites More sharing options...
Co.Jeep.Manche401 Posted May 18, 2014 Share Posted May 18, 2014 Ignore the red wires, that's some bull$#!& from the PO. Link to comment Share on other sites More sharing options...
ajohnson928 Posted May 18, 2014 Author Share Posted May 18, 2014 Yeah that's the part I've seen elsewhere. So, do I need to replace it or just keep on going along without it? Link to comment Share on other sites More sharing options...

91Pioneer Posted May 18, 2014 Share Posted May 18, 2014 EGR solenoid. I would "put it back" if I was you but I like to keep things nice and stock generally. Link to comment Share on other sites More sharing options...
ajohnson928 Posted May 18, 2014 Author Share Posted May 18, 2014 I'll have to add it to my JY list. Where does the other end of the vacuum line go? Link to comment Share on other sites More sharing options...

Geonovast Posted May 18, 2014 Share Posted May 18, 2014 FYI, that white block thing is your ballast resistor. It quiets the pump after startup. If you ever have a problem with the pump going out but it starts fine, first thing to try is to jump those two wires. Just file that away somewhere. :thumbsup: Link to comment Share on other sites More sharing options...
ajohnson928 Posted May 18, 2014 Author Share Posted May 18, 2014 Thanks for the link dainternetguy. And thanks for the info Geonovast, I'll keep that in mind for the future. Now, is a solenoid from the jy good enough or should I get a brand new one? Link to comment Share on other sites More sharing options...

64 Cheyenne Posted May 18, 2014 Share Posted May 18, 2014 Would a 4cyl have that solenoid? Link to comment Share on other sites More sharing options...

ParadiseMJ Posted May 18, 2014 Share Posted May 18, 2014 Do you have an EGR or is it blocked off. Some guys eliminate the EGR altogether, especially if it has an aftermarket header. Can't do it in CA, mostly because of the rumored commie pinko sympathizers. In Kentucky, if you don't have emissions testing, it could likely be gone.

ajohnson928 Posted May 18, 2014 Author Share Posted May 18, 2014 No the EGR is there but the solenoid isn't. Link to comment Share on other sites More sharing options...
