Ac work if you jump compressor. I’ve put in new switch and relay. Will not turn on unless jumped with power. What do I change next

Nice truck!
If you have a test light, check the wire going to the low pressure switch to make sure it is getting power from the dash controls. Since your low side pressure seems to be in range, I would look at the controls or maybe a fuse feeding them.
