I have either a P5000 or DP25K in my shop right now and I'm not getting any power to the solenoid at the injection pump. I have traced wires all the way back to the fuse and relay box. I found some corroded wires for the battery to those two blocks i repaired and replaced them and one of the wires that needs to get power isn't getting power. It's as if it has a bad relay but the relays are good. I was able to use a jumper wire to the wire I need to have power and it started right up. I'm not sure why its not working when everything is plugged in. Any thoughts? Sorry for the novel.
