Your help appreciated as always.
My Car will not start and my chap has used something called a noid light I think on one of the injectors and tells me no power,
Any thoughts?, relays and fuses appear fine,

Thanks in advance

thanks for your advice, my chap seemed to think is might be the crankshaft sensor, where exactly is it located?

thanks

thanks for that, assuming worse and that it is ecu failure is it easy to remove, and I get the impression repair is the only route as presumably new is not an option.
if so who best to repair?
is it possible to get to crankshaft sensor without a ramp?

problem originally started as not starting well when hot, but when left to cool would, now not starting at all?

many thanks
