FUEL FAIL 14 CODE 14

Typically code 24 is reserved for the ecu to ignition amplifier. Recheck your fault code by just switching the ignition to "on", wait 5 seconds, then re-check your code(s). Code 24 is uncommon, and very few people have documented this

Other possibilitie is the ignition amplifier is bad or the connection is corroded. The part is easy to get to, and is easily replaceable, but I would not suggest trying to test it yourself unless you know how to use a voltmeter.

If you want to replace it I would first buy a Haynes manual and follow the instructions (they have pictures).

Check additional details in the Jaguar Online Manual in this link: jag-lovers.org/ebooks-index; check the section 10 Engine >> 10.14 Ignition amplifier module (need to register for free).

Also, check this interesting info AJ6 4.0L Engine Management System Diagnostic Guide (pdf format).

Hope this helps; keep us updated.

Hi did you solve this problem

this has to do with the engines ability to warm up and meter the fuel. either the thermostat is sticking or the coolant temp sensor is out of range. there are 2 of them at least, one for the guage and one for the pcm. if you find it is the t-stat sticking, replace with jaguar parts.

my manual says fuel fail 14 deals with yourr coolant temperature sensor is no in operating range

code 24 is the ignition amplifier circuit

1st u need a service manual-it has pages of codes-ch engine lite can mean old 02 sensors-cheers mate

Check MASS AIR FLOW SENSOR , try to get a used one and fit to the car , it is very easy to install. And by the way the MASS is the part that is in connection with the air filter , the one that has an electrical connector. When installing make sure that it is tight and no leaks. This answer was based on your description and code supplied hope this would help

Fuel fail 46 is emission related and if I remember is related to the oxygen sensor/catalyst. I would reset the code by disconnecting the battery for 45 second and if it comes back on then start with a proper diag.
DO NOT REMOVE THE BATTERY TERMINALS UNTIL YOU MAKE SURE YOU HAVE THE RADIO CODE
Your welcome to email me with any other issues and if you dont have the radio code
