I don't understand that comment. All the fuel hoses are full of fuel all the time. By clamping off that relief line you will stop the accumulator from allowing pressure on the high side to bleed down quickly. This is not a permanent fix by any means but is a very legitimate way to test for the problem. The cold start injector,although electrically operated, still requires pressure from the fuel pump to work. It does not have it's own pump. The reason it works is that it will let fuel thru at much lower pressure than the mechanical injectors. But it still needs pressure and a working fuel pump.
