The grey fuel injector relay is something I had seen in the forums as being a problem, but I could never find one and figured this was maybe just on the 850s. I only have an electric fan relay in the cowling above the radiator.
My circuit diagram for 1997 V70 does show a 'main system relay' that appears to feed the fuel injection ECU, and I have found this in the engine fusebox.
I took it out to note the part number (9128164) and cleaned the terminals before replacing.
I've been out today and managed to restart twice within a few minutes of shutting off. Not conclusive as this would have been possible by chance previously. I will monitor it further.
