Been having this random issue since I bought the car if it sits for a day or more. Seems like the majority of the time that it sits for a day or more, the next time I try to start it, its hard to start, cranks over many more time than normal before firing. I'm leaning towards it being fuel system related, and with the thread about the cp4/duramax lawsuit, it's got me thinking. My VP44 truck would do this when I had a leaking return line, causing the fuel system to loose prime. But so far I haven't found any leaks. I've been trying to randomly run some treatment/cleaner through the fuel, thinking maybe its dirty/sticking injectors, which has seemed to bump the mpg slightly, but still the random hard starts. Any ideas or insights appreciated.
