The diagnostic trouble code (DTC) U1262 on a 2000 Lincoln LS indicates a Communication Bus Fault. So, this means one of the main modules is not working so I would start by checking the fuses this guide can help, please check the fuses with the key on.

Here are the fuse locations so you make sure you check them all. If you have a shorted fuel injector or oxygen sensor it will pop the fuse and cause the PCM not to get power. Check out the images (below). Please let us know what happens.
