Hello and welcome to JustAnswer!
P1693 is informational and just sets in the engine controller or powertrain control module when there is a code set in the opposite module.
P1287 sets when the injector pump module sees low voltage from the fuse system relay. This could be a handful of things and it will take some electrical testing to determine what is going on. Low battery voltage, a bad fuel system/ASD relay, a wiring issue between the relay and injector pump, or the injector pump itself can cause this.
