Does anyone know if I have to replace the entire power distribution box or is there an actual relay I can replace?
I haven't driven the XK in over a year. I've been busy with work and just haven't had the time or energy to mess with it. I started having issues when I put a new upper control arm on. I had to move everything around including the PDB. The starting became intermittent at that point. Today, I finally decided to get it going because I miss driving it. I jumped the starter with a remote starter switch and it started right up. No power is going to the small wire when I try to start the car so i know it's the relay but haven't found any hard information on what to change.
So no power to the fuse? I think it's on the underside of the distribution box. My memory isn't what it used to be. I think looking from the top you see something that looks like a grate. Under that. I read it somewhere, never had to deal with it. You'll probably have to work your way backwards from the fuse. From the underside of the PDB, FL037 red/white wire is coming from the fuse. You really should pull some DTC codes.
Sean, I've worked on cars a lot but I do not typically work with the electronics on them because I'm just dumb when it comes to that. But, I do have a question. The F19 30a fuse in the PDB is the starter fuse.(or so I believe it is) When I push the start button, the voltage goes to the starter relay, then to the fuse and the to the starter. Or so I'm hoping that's what it does. So my question is, can I check at the fuse if it's getting voltage or is the fuse before the starter relay? Hopefully that makes sense.

Well, the Jag is back working. I have NO CLUE how the hell it happened but there was a 25a fuse in 19. On your first post you said 19 30a. When I looked at my box I saw the 25a. I have never touched a fuse in that box so I'm not sure how it got a 25a in there. At some point it got put in but I'm glad it's working.
