I decided to start with the ECU with the fuel pump issue because it seemed like the easiest to diagnose. Then having leaned how to diagnose the connections in the ECU for the relay ground, the TPS issue ones should be easier to figure out.

Thats good once you get that one going again it will help you with the other two
This sketch is just part of the sketch I sent back a page focusing on the just the safety diode.
You can open uptake P8 and replace the diode but it might be a challenge if you are unfamiliar with working on circuit boards so I suggest you install the diode outside same as all later Guzzi's have. I'm pretty sure once you connect a new diode the pump will prime.
