You need to get a scan tool that will work with a 7.3 diesel and display live data- AutoEnginuity, Forscan, or one of the other options like a Snap On Solus, Verus, Modis, or Zeus, a Launch or XTool or Autel, something that will display live data - what the ECU is seeing - and not just read and clear codes.
Once you have a scan tool, plug it in to the OBD Data port under the dash, turn the key on, connect the tool to the ECU, and let us know if you see an RPM signal when the engine is being turned by the starter and the key is in the on position.
Do you have any friends who are better with diagnostics and maybe speak English? I can help you fix your issues, but only if you can understand what I am telling you to do.
