help with data link adapters and codes

[Midland]

Also found a list of International fault codes. Some of my codes are matching those. Some point to Instrument cluster error and/bad ECM. Hadn't given much thought to a bad ECM since I was getting ABS codes and other similar datalink codes. OTOH, when it did start Saturday, heard the lift pump running (usually don't hear it under this symptom) and it fired right up. Headed off to check the oil pressure right now. Then cobble an adapter to get into the weatherpack connector. Fuel pressure while cranking--makes sense since it acts like out of fuel. Also found detailed troubleshooting in OnCommand for all sorts of stuff like this, more ways to test J1939, etc, which will be next after verifying ECM is still functioning. Unfortunately, many other mandatory family distractions that are going to delay me on some of this. Thanks to all for getting me this far.
