P1282 is a fuel pump relay control (coil) fault.
The fuel pump may be kicking on and off due to the control coil fault.
You may want to go to your PDC and pull the fuel pump relay and make sure the relay pin cavities in the PDC base are not corroded or pushed down.
Some times just removing and reinstalling a relay will clean off the relay pins and cavities enough to refresh the contacts and do away with a fault.
If in doubt, swap the fuel pump relay with the radiator electric fan relay and see what happens.
This is unrelated to the other DTC.
Note that the fuel pump relay control coil is powered from fuse F11 in the JB. It also powers the ASD relay control coil. If F11 pins are corroded it may be causing the FP and the ASD relay to drop out.
