My l200 has been parked up for 8 months. Recently I tried to start it but the battery was flat so I tried with jump leads. The first time I tried the engine glow plug light came on then went off like normal. Couldn't get enough power through the leads so the next day I bought a new battery. However it still won't start and the glow plug light doesn't appear on the dash at all. I've checked and there is no voltage at the glow plug busbar or the coolant temperature sensor. Is there a fuse specifically for this circuit?
