Range rover Sport 2014 4.4 V8 L494 none start issue !
Good evening all,

my close friend has bought a car recently off eBay as a light front end crashed damaged, when we picked the car up the storey from the guy that owned it was that he had a light crash front end bumper lights job and rad pack, (no air bags went off) so not too bad but repairable, it was advertised as a non runner, when we asked him more about it he said that the car was running after the light crash, it was removed then he claimed on the insurance and then the car went to Copart, he then bought the car back from Copart and then advertised it for sale.

so far me and my friend have plugged in the car and read all fault codes,

fault on car - engine will crank but wont start.
engine runs on brake cleaner in inlet so engine is ok
no pulse from injector when a node light is fitted to the injector plug.

codes are -

P250A-37 Permanent Lin bus A
P062D-11 temporary Fuel injector driver circuit performance (bank 1)
P165D-87 Permanent Active grill air shutter control circuit
P0607-00 Permanent Control module performance

we have a crank speed of 170 RPM on the live data


we have took his ecu reprogramed it with k-tag and put in onto another car and is started fine twice with no issues so its not the engine control module.

we have checked the crank sensor to the ecu and we are getting 70volt signal on the scope.

we have also communicated with all 30 control modules and it will rear live data.

we have disconnected the front n/s headlamp and the Lin bus A code goes away he has changed the headlights on the car with the rad pack and front bumper.

All engine control pin outs seems to be ok and no powers or grounds missing.

we have changed the main battery and programmed.
2nd battery was tested and is ok.
all testing has been done with a good quality battery charger on at all times.

any suggestions are welcome is there anything we are missing or have not checked?


any help much apricated we have been using a snap on and autel diagnostics, we do have access to a SDD but have not yet put that on the car.
