Car wont start fault code 47. how to fix? 1993 XJ6

I recommend you have your battery tested. The starter requires MUCH more power than the radio does. You could also see if the car starts with a jump start. Also, as a general rule, a battery is only good for 3-4 years so if it is older than that it wants to be replaced anyhow : )

Good luck!!!

under the bonnet there is a fuse box on the inner wing there is a fuse in there that might have blown for the charging circuit

let me know if this helps mate
cheers

fuelfail37 is a egr problem it should not be there on your aj6 engined car has its not got a egr valve? on a uk spec it has not got one. car in the us spec it may have one in which case its siezed/stuck or the solenoid or wiring to it is at fault.try and clear it by disconnecting the battery for a few minutes then reconnect

PROBLEM COULD BE FAULTY FUEL PUMP OR IGNITION MODULE.CHECK FUEL PRESSURE SHOULD BE 41 - 47 PSI. IF NO FUEL PRESSURE TO LOW REPLACE FUEL FILTER.STILL LOW FUEL PUMP FAULTY.IF FUEL PUMP DONT RUN CHECK FUSE AND RELAY.IF FUSE RELAY GOOD PUMP BAD.IF FUEL SYSTEM OKAY USE A SPARK TESTER TO CHECK FOR SPARK AT SPARK PLUGS IF NOT CHECK IGNITION MODULE FUSE IF OKAY IGNITION MODULE COULD BE BAD.USE A CODE SCANNER TO CHECK FOR FAULT CODE IN PCM AND IGNITION MODULE.THIS SAVE YOU FROM SPENDING TOO MUCH MONEY.

Fault code P1178Rich Fuelling Trim, Long Term (AMFR)Check for manifold air leaks, rectify as necessary Check for recorded MAFS fault code, rectify as necessary Clear fault code and perform service drive cycle to verify fault cleared Contact Jaguar Service Hotline if fault still present.

Taken from the Jag service manual.

Depending on milage, check timing.

remove the battery for 2 minutes. it might reset the problem. if not try a spare key

Check you fuel pump.

Rate this.

Generally speaking if a EFI car wont start but will "turn over" there are many points in the fuel system that could be hindering the process. I would start with the fuel filter. Also if when you begin to turn the ignition on you should be able to hear a light humming noise (this is your fuel pump engaging). If you dont hear this humming it could mean a bad fuel pump. A temporary fix is to take a none abrasive or punctioning object and tap on the fuel tank... Fuel relay would have to be checked electronically...like the previous poster stated...

The started is located on the left rear corner of the engine, ontop of the car, not underneath.
If you look in the engine bay down ontop of the transmission on the elft rear corner you can see it.
I do not suggest hitting it with a hammer, most of these started now have plastic gears unlike the older ones.
Usually it wont come to life by hitting it.
