I plugged my shiny new Landrover / Jaguar Foxwell NT510 PRO Multi System Scanner into my car yesterday evening and read the codes.

I got a few historical failures and the P0100B code that I expected.

I cleared the codes and did another scan which returned only the P0100B code.

I then switched off the car and disconnected the code reader.

Now I can't start the car.

The ignition comes on and all the electrics work (a/c seats, lights, but the car won't crank).

What could I have possibly done wrong?

Please, any suggestions?

I knew there was a reason I always took it to the mechanic!

Also, I cant read the codes from the unit on my computer.

Once again HELP HELP HELP!

OK here goes...

Have you tried both/all keys?

Have you tried inserting the key into the smart key socket in the center console cubby hole (I assume you still have the 2011 XKR your profile mentions)?

Have you tried disconnecting the battery for about half an hour and then reconnecting?

Can you read codes at all, e.g. with any sort of code-reading device?

Highly unlikely you'll have done anything any damage just with reading and clearing codes I'd think.

Well, got home from work and removed the battery cover trim.

Said to the wife "I'll just give it another go before I start disconnecting things."

Jumped in the car, pressed the Start button....

Heard the relay click and the fuel pump prime then.................I was just about to take my finger off the button, then Vroom!

There must have been about a five second delay before it started, but it seemed a lot longer than that.

Anyway, the crisis seems to be over for now, phew!

Had a run round the block then a few more "normal" restarts and things appear to be fine.

Just got the original issue to deal with now.

I'm sure I heard the bloody thing sniggering when I was going back indoors!

Speaking from experience, be very careful.

I've immobilized my S Type on a few occasions with non jaguar software. It's a long boring story.

Anyway. If you are going to attempt DIY fixing of your car. Keep your battery on charge while you mess about with the code reader. The batteries go flat very qui
