Check the EFI main relay, the circuit opening relay, and the fuel pump relay. Inside the fuel pump relay there is a switch controlled by a coil. During start, the fuel pump gets full power for a couple of seconds to build up pressure. Once pressure is good, the fuel pump relay is supposed to switch (via the coil) the fuel pump to reduced power. If the coil in the relay is bad, the reduced power setting is not available and the fuel pump will run at full power all the time. At this heavy current draw, it won't be long until the EFI fuse blows. This would also give more pressure than is necessary to the cold start fuel injector which runs on a timer. This extra pressure during the time that the cold start injector is operating may be the reason the engine is flooding with fuel.
