Cranks but will not start

I added ten gallons of fresh fuel and it sounds like the fuel pump is working. I did try a bit of starting fluid in the intake with no sign of firing. I will check for spark. One follow up question, as I am checking for the most obvious things first, should the green wire connected to the fuel block next to the battery be going to ground all the time? My red terminal has 12 volts but the green wire attached to the post with a nut does not have continuity to ground and I am wondering if the fusible link on the green wire has gone bad.

Thank you so much for your quick reply. Please forgive me for not being clear. The photo below shows the fuse block next the to PCM with the red and green terminals at the very top. The red from the battery has 12 volts plus but the green post does not have have continuity to ground but I am not sure if it is supposed to be? I have started to expose the fusible link part of the green wire but stopped until I check the fuel issue you recommended. Should those two posts show 12 volts between them? As far as the fuel goes, I was hoping that even old fuel would allow the vehicle to try and at least sputter. I added ten gallons of treated fuel to the tank to hopefully dilute the few gallons of bad fuel in there (it was treated with fuel stabilizer), but what I do not know is if bad fuel will actually clog up a fuel filter or jam up a fuel pump? I appreciate any help you can offer so that I can concentrate on the most likely cause of the problem.
