Thanks guys, after that post I didn't have the problem but it happened yesterday and I didnt manage to get it started, I will try the injectors today. It could well be the temp sensor as well because the gauge flys up occasionaly even though the engine is running fine..
Over the last couple of month's my K11 has had trouble starting.
It will only happen when left for a couple of days. Initially I was taking the fuse for the fuel pump out and turning it over then putting it back in and it worked fine. But after a few times it didn't work again.
