Hi all,
I've had an issue with the engine pretty much ever since I got the car. In short, it sometimes refuses to start on a warm engine. This usually happens when the engine has been shut off for between 5 and 15 minutes. Anything shorter or longer than that, and it works perfectly. When this happens, it acts as if its flooded. It smells a bit, and if I give it a few minutes and then crank for a long time with the throttle wide open, it will finally fire. Now, I've been trying hard to find a logical explanation and it has occurred to me that maybe one or more injectors don't close properly. This would cause pressurised fuel to dribble into the manifold until the pressure is low enough that the leak stops. My theory is that this process takes a few minutes, so that if you catch it before 5 minutes have elapsed, the amount of leaked fuel is insufficient to flood the engine. Then you move into the flooded stage where it will not start, and then finally into the stage where it's sat long enough for most of the fuel to have evaporated and it starts fine again.
Have any of you experienced something like this and do you think my theory makes sense? I suppose a pressure gauge on the fuel rail would be the easiest way to test for leaks..? Are the injectors easy to replace?
Your thoughts, please.
Henrik
