Does any know what these codes mean. U1262. J1850 Bus. Also the ECM gets hot like you can't hold your hand on it. Is that normal. It's a 99 mustang GT.

If this were my car I would first rule out all devices connected to the PCM. For example:
  • shorted ignition coil
  • shorted injector
  • shorted sensor
With a problem in the ignition circuit being top of the list.

>>From the Ford service manual
U1262 SCP Communication Bus Fault - Perform Network Communications Test Go to Workshop Manual Section 418-00, Module Communications Network
<<

The Ford workshop manual has a whole series of pinpoint tests to verify the Module Communication Network. If interested in getting a full set of Ford service manuals and wiring diagrams for your car I maybe able to help. PM if interested.

Hint. Often problems in the MCP are wiring and ground related. Think back about any recent work done. How about any evidence of water or rodent damage?

Glad you got it figured out, usually not the problem. What are you replacing it with?

To me, a basket case would be a engine with rod thrown through the side of the block. Any thing less, not a basket case. imp

In the field of automobile restoration, the term “basket case” means different things to different people. In general, it refers to a car that, no matter how amazing it once was, may be past the point of saving
In my day it usually meant a car that has been taken apart by someone unable or unwilling to reassemble it,also assemblies like the carburetor(had a lot of Qudrajet's brought into the shop in pieces)that OP try to rebuild and have to give up.
May mean different things to different people but they are all not good!
