Hi folks,

I'm hoping one of you will know how to cure the issue my 8V is suffering with. Whilst coming home from a two day tour of Wales, having covered a couple of hundred miles without issue, I pulled up to give my legs a stretch, as I had twice before during the day. However, when I went to turn the bike on this time, the rev counter went through its usual sweep and the GRiSO sign came and went, only to be replaced by the word SERVICE.

The starter kicks in and turns the motor over just fine and the petrol pump sounds to be priming, but it won't fire up. I checked through the diagnostics and ECU 54 is showing a fault.

Has anyone here got any idea what would have caused this and what the likely course of action to fix it will be?

Thanks in advance all,

Phase sensor I think.
