Johnnydiscovey Posted April 21, 2017 Share Posted April 21, 2017 My Disco 06 will not cut off engine unless I shut off lights. I can shut off and take key out. It still runs. The second I switch off lights, it stops. Any ideas? I have a leak from sunroof down on the passangers footwell. Had some cables rewired as suspension fault were constant and navigation stopped working. Quote Link to comment Share on other sites More sharing options...

Peaklander Posted April 21, 2017 Share Posted April 21, 2017 A live from lights shorting onto the fuel solenoid at the injection pump perhaps? How do you start it? Need the lights on then too? Quote Link to comment Share on other sites More sharing options...
Johnnydiscovey Posted April 22, 2017 Author Share Posted April 22, 2017 The lights can be off when starting. No problem starting it. Someone said it could be shortcut with the el to trailer hook. I removed all fuses there, but problems still. Quote Link to comment Share on other sites More sharing options...
Puffernutter Posted April 22, 2017 Share Posted April 22, 2017 The stop solenoid will only require little current to keep it open enough to let enough fuel through to idle. Step 1 is when it is doing this to remove the feed to the stop solenoid at the stop solenoid and prove this is the problem. If this is the case, the stop solenoid is getting a small leakage current and it may not be the lighting circuit, it could be anywhere as electricity is fickle stuff! Let us know if it stops with the feed removed. Cheers Peter 1 Quote Link to comment Share on other sites More sharing options...
Johnnydiscovey Posted April 23, 2017 Author Share Posted April 23, 2017 I am not a mechanic so I have to explain this to the garage. Fault search can be expensive. Is this what you are talking about? See link Quote Link to comment Share on other sites More sharing options...
dave88sw Posted April 23, 2017 Share Posted April 23, 2017 If your Discovery is an 06 it will be a TDV6 and therefore won't have a traditional fuel stop solenoid, it will most likely just stop telling the injectors to fire. It sound to me like you have a corroded earth somewhere, the engine ecu might be earthing via the lighting circuit. It's difficult to say where the fault could be, it's obviously not ideal having the sunroof leaking into the car as parts of the main loom run under the plastic trim on the sills and any connections within that section quickly corrode and fail. 1 Quote Link to comment Share on other sites More sharing options...
Johnnydiscovey Posted April 23, 2017 Author Share Posted April 23, 2017 Thank you Dave. I know the garage opened up the foot well and into the sills that has all cables in it. But the bundle of wires are badly proteced they said. Quote Link to comment Share on other sites More sharing options...
