Installed a new battery after she overheated and wouldnt start. It started with a jump but seemed the battery was dead Replaced with a new battery Turned the key and nothing. All lights radio etc work. Dash says gear box fault but it started prior from a jump Even a jump with the new battery cant get the starter to make a peep.
Is there a reset button somewhere

 

You can try the inertia switch. It is located on the passenger side footwell. The should be a cover on the side of the footwell that you can remove. Push the button on the top of the switch in to reset it.
The most likely problem is bad battery cable check the ends of the cable for corrosion and frayed broken wires. They are the weak point between the battery and the starter.
You can also try a hard reset by taking the negative cable off and holding it against the positive cable for 30 seconds.
Give those a try and report back so we can search further.

 

Thx Vern
Checked the cables Seem in good shape
Have power for all accessories:heat radio power seats windows seaterheaters etc
I will try when I get home and let you know

 

+1 on the Battery cables...They can look good, but looks can be deceiving....Inertia Switch is also a possibility as mentioned.

 

The hard reset worked ......Alleluia...... Thank you all so much for the help
Now how do I get the little yellow light to go out
Looks like an engine
It wasnt on prior to the over heat episode

 

You need an OBD scanner. Take it to a local autozone, oreiily's parts store and have the codes read. Write them down and report back. Then have them clear the codes and check engine light. Let us know if it comes back on after a few trips.
One really needs a code reader if you are going to work on a Jag.

 

I will get a code reader for sure. Where do you plug it in
I noticed under the dash on the driver side there is a plug like thing

 

Vern
I unplugged a couple of the sensors on the engine and guess what......engine light is out
Gone She runs great

 

Good to here you have it running again. Unplugging sensors might turn off the light but it doesn't fix the problem.
The large rectangular pin socket is the OBD port where the reader plugs in.
Try to get the codes as soon as possible.

 

Is this your first car?

 

no I had an 02 x type 2.5 but it was totalled I was t boned
This is just like it but 3.0

 

Is there an inside trunk release Cant locate it

 

The handbook only shows the key fob and the push button for trunk release.
