Hi Joe,
Many thanks for your input.
Afraid it's too old for a touch screen.
I hooked up an OBD11 but could not register any faults.
One thing I forgot to mention, the first time I hooked up the OBD and tried to read the faults, the engine started.
I drove about 10 miles, stopped and started twice, no problem. I thought I had solved the problem. Parked the car up and when I went back to it the next day it wouldn't start and hasn't done so since.
I'm hoping it's not the dreaded intermitant wiring fault.
