I have a 1999 searay 190 bowrider w/4.3 fuel injection. When I go out it will start and run great shut it off and start back fine but after a few shut downs and start ups it will not start back had to be towed in twice. I have took the one way valve.out.of the fuel line and seem like it fixed the problem but that's what I get for thinking. The last time I took it out it done it again but this time I finally got it started back after a few trys. It popped and cracked a few times and then started running fine. I was thinking maybe the coil or coils getting hot or fuel pump but was told that when a fuel pump goes.out it normally just stops. This has happened three times anyone got any ideas. Thks
