So I run into this problem like once every 5 starts. Key is in, turn on, all lights come up, glow plug indicator and the normal beeps. Turn key to start, and nothing happens. Turn off, remove key, repeat and it starts as normal. Any ideas where I should start looking? It almost always starts on the 2nd attempt...if not then on the third. But I'm a little paranoid that at some point it wont.
