My V50 has developed a starting issue. When turning the key to start the engine turns briefly then kicks back on the starter as if it wants to start. It getting progressively worse, I'm not getting a full turn of the engine before it kicks back, it feels as though it wants to start like there is compression there but something's stopping it from firing up, happens both hot and cold starting. Engine runs great, idles smoothly, fuel consumption mid 40's avg'.
Any pointers in the right direction to finding a remedy, I'm fairly mechanically competent so capable of putting it right with some ideas where to begin.
