I am still no where near getting a cough or splutter out of my 800. The engine will crank but the injectors are not injecting and the spark plugs are not sparking. There is 12v to the coil and fuel is passing through the filter in the engine bay.
I have had a replacement crank sensor which did not solve the issue. What else could have gone wrong? Both ecu's are clean and spotless inside and out

Help?!

It has to be either a wiring fault in the engine bay woring loom.

It would be handy to see if the ECU is getting power....it doesn't sound like it is.
Could well be a relay or fuse problem....but again, you need to know where to look.

Unless you have the info and expertise, this might well be a job for an auto-electrician.
