2006 Avalanche w/6.2 Black Scorpion. For whatever reason after running and then shutting down for more than 30mins, it will not start. It seems like a vapor lock. Runs good with no hesitation at all when running. I installed a new booster pump, water separated filter and fuel filter, but it still does it. I managed to get it started by using full throttle a few time. I’ve also had to be towed in a few times and have start without any problem in a few hours. After looking online, it seems to be a common problem, but I haven’t found a fix. If anyone has any idea, please help. Also, where is the fuel cooler installed on this thing and is it even possible to get to it without removing the entire engine.

Engine temp reads 220F - Would you believe it?

New (to me) '01 Concourse with Scorpion Engine. I have some issues but one is the classic sign of vapor lock. Run along, all is well, run slow and the boat stalls. Cranks, catches and dies. I hear the fuel pump. Eventually it starts up. Now the temp gauge is pushing 220, the impeller was changed 4 days ago when delivered. Could this be true? I'd see steam, wouldn't I? Thanks for your thoughts. jz
