[Alpine]

This is a continuation of my earlier post when I said I broke down, but I thought I'd put this question into a new post.

So my problem has developed into not starting just after the engine has warmed up. If I let it cool it will start.

My code reader says no codes, but I don't trust it to be right

I know the coolant temperature sensor has been mentioned as a likely cause (although my temp. gauge reads ok).

I'm just trying to work out if there are other likely sensors or things that could be at fault?

eg. could the crank position sensor play up in this way?

Cheers
