[gregxjr40]

help my 1990 my xjr40A will not start when engine warm, starts on the button when cold but pop to the garage for a pint of milk and i`m stranded when i come out. tried wriggling wires & selecting gears etc then all of a sudden she starts. any ideas?

Hello, may I suggest that you take a look at my final post under the heading 'Engine starts and idles etc'. From my investigations and testing I would recommend replacing the crank position sensor. Hope this helps.
