Have a 2003 Jag xj8. Got home parked up, tried to use it a couple of days later, and it would not start. the battery is fairly new, but tried to jump start and charge the battery but still nothing. The only thing was the fan whirring when I switched on, all other electric parts seemed to work.

 

Was it cranking the engine as per normal?

 

Ni it wasn't. Nothing at all.

 

I suggest that you have the battery tested under load, testing with a little electronic

box is NBG. Batteries can fail "just like that".

If you can't get into the boot use the key in the boot lock.

It may not be the battery but you need to know.

 

Are you able to shift it into the various gears? Can you get it into Neutral or anything else (foot on brake of course)?

My wife's 2005 just had the infamous ZF shifter cable bracket bolts fall out. Luckily, it occurred right in our driveway, and the one bolt that actually fell out was laying right there. I used a lock washer when reinstalling them so they stay put from now on.

When they loosen and fall out, you can't start the car if it is not actually in Park (our Jag was stuck in Park, but the Reverse selection was lit up, won't start of course, and the parking brake failure occurs, etc.). The bolts are two 8mm suckers that hold the shifter cable bracket to the transmission, driver's side, easy to get to when you jack up the car and look.

 

Can any one help. The car WILL not start, the electrics work but it will not start the engine is dead. I eed to get it to a garage but cannot get it into neutral because of the electronic hand brake. How do I get it into neutral anyone???

 

If the battery is low one of the symptoms is that the park brake will not disengage and you won't be able to move the car. Have you removed the battery and had it load tested? Make sure the battery is fully charged and the park brake should disengage.

 

Done all of that.

 

You have had the battery tested under load and not with a handheld electronic box and

the battery voltage held up under load-please confirm.

With the ignition on can you hear the parkbrake operating when you press

and lift the chrome switch or when you remove the key from the ign?

 

Have done all of that, just wat to get thegear into neutral and handbrake off.

 

Does the engine turn over? The PATS lamp in the middle of the dash, please describe it's illumination action when the key is inserted. (blinking? solid?)

A brake pedal/gearshift interlock system is incorporated in the automatic gear selector mechanism.

To move the gear selector from Park:

1. Turn the ignition key to position II or start the engine.

2. Press the brake pedal.

3. Move the lever from Park.

To release the Emergency Brake, you must place the ignition key to position II, press the brake pedal and press the Emergency Brake button.

 

Thaanks for the tip, but without the battery engaging, it does not work. I need to be able to get it to a garage. Therefore I have to get the rear wheels off the ground and in neutral with park brake off. I cannot do this

 

Colin, you stated "The only thing was the fan whirring when I switched on, all other electric parts seemed to work." You don't need the vehicle to start, you simply need voltage applied with the ignition in position II for both operations. You also did not reveal what the PATS LED in the dash was doing when you placed the key in the ignition barrel. I want to try to get you some help, but if you give us erroneous information, then it will be impossible.

 

Sorry didn't mean to. When I switch on, the lights on the dash come on, the fan belt starts "whirring". I have tried all other electric parts the Air con; indicators, horn etc
Just want to be able to disengage the gear and get it towed,

 

Have you checked the inertia switch?

Do you have a spare key?

Try spare key if you have one.

You may have a possible PATS issue (security system) which needs reprograming.

 

By inertia switch you mean the one that stops the fuel flow? Yes checked. Spare keys checked.

As I have said have had a local garage (not Jaguar) try and move the car, they cannot they have contacted Jaguar (in France) but they seem unable to help. Surely there is a way to get the car into neutral??

 

Does this help?
"How To Get a 2004-2009 Jaguar XJ8 Out of Park In an Emergency"

 

Chris, while the OP could manually depress the solenoid to get out of Park, it won't release the Emergency Brake, that would have to be manually driven at the connector in the boot. However, the OP has never stated if the engine will turn over but not fire up, or if the PATS LED has blocked starter engagement. If the vehicle has power, the most effective way to get to the results needed is to turn the ignition to the run position, (position II) and depress the brake pedal to release the interlock on the shift lever, and take it out of park, which will also release the Emergency Brake. You can't just press the brake and get this done, the ignition must be in the run position, then press the brake pedal, and he has yet to confirm he has tried this.

 

The ENGINE is NOT turning over at all
