Hey guys, fresh rebuild here on this boat and I have most of what I need to run. It is MEFI 5 for starters, I have spark, it cranks over, timing is correct, fuel pressure at the fuel rail. My injectors are not firing. I put a fuel injector test light in the plug on all cylinders and no light is coming on when cranking. I have a solid ground to one side of the injector plug, and the other side I would imagine delivers +12v to activate the fuel injector. For some reason they are not working. I’m not sure what else to look for, I’m going to go back and check all grounds. Any ideas?
