For context, I just picked up a brand new '91 F250 with the 7.3 IDI and it ran great for 2 days until I went to start it the other day and it just sat there cranking over and over no matter how many time I would cycle the glow plugs. Batteries/starter/glow plug relay and Glowplugs were all replaced within 20k miles. So from what im seeing online all the main issues with a no start should be fixed but nothing happens besides continus cranking. Any help would be accepted, I juat want to get this fixed so I can start rhe restoration

So as the title says im installing a amp and a 12 inch sub in the trunk. I have already ran my power wire and got the ground wire in a good spot, in the past ive alwayd used RCA cables plugged into the head unit but with that not possible can someone show me how they installed there RCA adapter. Im trying to not get in over my head here and just looking for some help here. Thanks in advance
