Hello
I have a 1990 XJ40 whose Engine light just came on, with Fuel Fail 23 as the troubleshooting code.
Does anyone know exactly what this means?
Regards
Richard

Thank you for getting back to me.
The manual says it's too rich, all right.
But, since the air filter is less than one week old, I just don't know what to do about.
Any suggestions how to identify what the problem truly is --and how to fix it?
Thanks
Regards
Richard
Hi,
Rich running, sure, but if I was you the very first thing to check is fuel pressure, then plugs, then lambda sensor.
Good luck,
Blake
And it is a very good idea to check the lambda sensor first.
