I have a5.7 Mercruser with EFI. Last couple of times out had a no start condition after shutting down when engine was warm. Let boat sit for an hour it will start fine. Last trip out after changing plugs, plug wires, rotor, distributor cap, module was at full throttle and engine popped and stalled now no start at all even after cooled down. Turns over sprayed starter fluid in through air box still no start put on plug tester and have no spark. Could this be the coil? Any help would be awesome tired of throwing parts at it.
