Hey guys got another brain buster for you. When i drive my gen 1 3.0 for a while, say half an hour, so its warmed up, shut it down and try to start it five minutes or so later it doesn't want to fire. when you unplug the injectors then crank it, it will start and run as long as you plug the injectors back in really fast. Any ideas? as usual any help is greatly appreciated.
