Could be a few things but start with the basics.
Power at the + side of coil?
If no power, check at the key and is the kill switch tripped?
Where are you finding power?

No power in the + side of coil and no power in the electronic system , remember is a MPI engine.
and more the engine circuit breaker only kill the starter,
I checked the kill switch it’s good and only kill the coil power
I Install a Vessel View Mobile and the same not power to work.
I disassembled all the peripherals of the engine to change the head, but assembled correct all the wires and connections
Understand MPI
Breaker doesn't just kill the start, power from bat, to breaker, from breaker to red/purple feeding motor and ignition key, to purple wire, to 20 amp fuse or breaker, to gauges, to kill switch, to coil and motor ignition/alternator power
Since nothing comes ON, check power at key purple wire, then 20 amp fuse
I checked step by step you instructions and no power , but I recked the 15 amp fuse on the direct wire from battery to ECU and this fuse was good in appearance but when I tested the continuity it’s doesn’t work , I changed the fuse
and have power in the system.
And the engine started after a long time....

Different ground
The main electrical engine harness has a ground which is connected where your showing.
The EFI harness can have 1 to 3 additional ground connections. They are all smaller wires and connections are at different points
Just remembered the motor was partially sunk in salt water. If water got into the harness or connectors there could be all kinds of gremlins which would keep showing up.
The wire in second pick would not be a harness ground, it would go to another accessory which may not have been installed.
Thinking about it more, it can also be on the power side. Each sensor has power, ground and a feed going to the PCM. The power and ground come from a single wire harness point. So the engine connectors, wiring harness to/from helm and anywhere in between. The problem is the sensor's connections to the PCM are showing invalid which is caused by a bad sensor or bead connection. Since there is more then one sensor this would say there is something in common.
Here is part wiring on a 555 PCM, this is just to show you how the sensors are connected, and may not be exactly how yours are done
I can help you a little with the vesselview. You can not clear the code from the engine. There is a clear code for the app only. You can clear them from the app than see if they come back which it sounds like it will with what you have going on. If we have the same version the vessel view does have oil pressure and water pressure readings but they are kind of hard to get to.
Once the boat is connected tap on the rpm reading and this will take you to the gauge pages where you can select 4 different pages made up of all sensor readings your engine has, even some you do not. For example, mine shows incoming seawater temp, I do not have that sensor so it just shows 32.
You have to turn the key on to where the vessel view turns on to connect and get to what I was telling you about. If you are not connected to your engine than the pages will not show up.
