clbarclay:
Not sure just what the level of risk is but it is possible to damage an ECU by the current earthing through the vehicle during welding. As a precaution I always disconnect and store ECUs in a safe place before welding.

pugstu:
would it still spark if the ecu was [!Expletive Deleted!] though?

jjsaul:
so long as the battery is d/c'ed the ecu should be fine when welding (unless you weld the ecu to the floor or something  :lol: )

spark at the plugs?
if you have a spark and no starting check all the various wires and cables to the AFM / injection system.
also check you havent got a petrol leak between the pump and engine bay....mine did that - i wondered why it wasnt starting then realised there was a big pool of petrol forming under the vehicle  :roll:

fezzy192:
do range rovers have some kind of crank sensor ???

if so maybe its that do you have the injectors firing when you crank ??

ScrumpyJack:
My 3.9 has an inertia button, like a fuel cut off, reset button, it's under the front passenger seat, get to it from the back,
if that's not it check the fuses under the drivers seat, there is a block of 3 check the fuses first but also check the connections, 1 of mine came loose took 2 days to find that 1, mind you Mr AA didn't know either.
