I have a Mk4 Golf GTI, 1.8T engine. A few days back, I had this issue where my engine did not start. After ignition, as I tried to fire the engine, it kept cranking but did not fire the engine at all. This happened about two weeks ago, after which I left the car alone for 15 minutes. When I tried again, the engine fired and everything was normal again. Following that the car has been running OK, sometimes I do feel something is different while starting the engine. Now, today the same problem came up, where the engine kept cranking, but did not fire. I was almost going to give up, when I tried again and there, it fired!
I'm a bit worried about what the issue could be. I've been trying to do some reading on similar issues faced by others, but I'm getting conflicting ideas.
Could someone please help out?
