targa Posted April 25, 2011 Share Posted April 25, 2011 JDM R35 2 1/2 years old Tried to start it about 3 weeks ago, the battery was a bit low as I hadn't used the car for 2 months. First it wouldn't start. all dash light on, starter button nothing, but the headlights came on, and the headlight switch could not turn them off. Then it finally started,but It wold stop. Tried disconecting the battery, car still running, headlight still on, no way to stop it,apart from clamping a fuel line. Tok it for a drive, after about 6 kms the headlights went off. drove for 12 kms, stopped, and the starter switch stopped the car and it started again normally. Everything operating as new again. Tried to start it again yesterday, dash lights on, headlights on again, starter switch nothing. Disconected the battery, dash light and headlight off. So I charged the battery over night and tried again this morning, same thing again , dash and headlight on but it won't start. Had to disconected the battery to turn the lights off. Help Help any ideas all please??????? Link to comment https://www.sau.com.au/forums/topic/362025-help-r35-gone-crazy-again/ Share on other sites More sharing options...

Daleo Posted April 25, 2011 Share Posted April 25, 2011 +1 for new battery. Cars do all kinds of weird things when they don't have enough current to run their systems.

targa Posted April 25, 2011 Author Share Posted April 25, 2011 Thanks guys but it's not the battery. Battery shows 12.9 volts plus tried a jump starter as well. why are the headlight coming on? Why wonldn't the engine turn off when it was running? It must be to do with the can bus system somewhere. might need a consult 3 to check it out.

Batteries can show 14V and still be stuffed, especially after sitting around unused then quickly charged Link to comment https://www.sau.com.au/forums/topic/362025-help-r35-gone-crazy-again/#findComment-5778375 Share on other sites More sharing options...

Martin Donnon Posted April 25, 2011 Share Posted April 25, 2011 You should Water Spray those brakes..... Two things I would do - Replace battery just for the fun of it - stop any stray noise potentially on the CAN bus. Secondly drop the Steering Lock and lubricate the firing pin I know none of this makes any sense - but give it a go Link to comment https://www.sau.com.au/forums/topic/362025-help-r35-gone-crazy-again/#findComment-5779142 Share on other sites More sharing options...
