The Dk Grn/WHT wire is ground. The ECM completes the ground for the circuit. A meter measures voltage differences between the wires. It looks like the relay is shorted and the wires have 12V on both, which is why you are measuring 0v potential difference.

A new ice cube 30A 12V relay is $10. I would try it out and see what happens. You have one in your truck fuse box you could try out and see if it works.
Was out today and the boat fired right up and ran fine.... went back to the dock and let it idle for a while and then eventually the boat shut off..... i could not get it started again after that.... I thought I ran the boat out of fuel but that was not the case. The engine is for sure not getting fuel for whatever reason.... I have almost identical systems and this is what I have checked so far....

1. fuel pump power on when bench tested and when I jump the pink to grey wire on the fuse block
2. all (3) blue fuses are good
3. the fuel pump does NOT prime and does NOT get the 2 seconds of power at key on. There is no power running to the fuel pump
4. the relays do not click
5. Waiting to try and swap relays but I did rotate them around as they are all the same and no result was different.

any thoughts here? PLEASE HELP!
