What does it mean:Fuel 44 Fail in the VCM in a jaguar 1991 xj6 sovereign?

You can buy the actual Bosch injector plugs new with crimp terminals. Here is a link to an ebay listing that you can use as a start for possible sources -
Bosch Fuel Injector Connector Jaguar XJ6 4 2 69 87 eBay

With the car in key position 2, the position right before you turn it to start, hit the VCM button on the right trip meter, you will get a code.

Fuse #1 is for the electrioc cooling fan at the radiator. May just be loose or need re-seating and/or cleaning of the contacts.

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

Fuel Fail 24 is the code for the Ignition Amplifier Module. These are very difficult to find for older Jags because Jaguar does not make them anymore. I also do not know of any aftermarket companies that make them new. I do know you can get a remanufactured one from www.jagbits.com. It will cost you somewhere around $300 but without it, the car is junk. If you need any information on replacing it, let me know, and I will be glad to walk you through it.

Hi

Lamba Sensor Faulty. (Oxygen Sensor) On the exhaust down pipe.

Good Luck !

A FixYa would be nice... Thanks.....John.

this is the most common error code, just means the one of the nods in fuel pump misfired, on every model other than the ones for usa market, after clearing the error code on vcm the check engine light would reset. for our cars its programmed to stay on.
also get fail 17 fuel 17 same thing
it will not effect the running of the car or its performance
may run a little rich

Fuel fail 44 usually indicates the lambda sensor is faulty. (oxygen sensor)
