Hi I have a 97 r reg 3.9 efi auto discovery that won’t run. I took it to the shops the other weekend and it cut out half way there but restarted fine but then cut out on the way back and wouldn’t start. I’ve just charged the battery and tried to start it fired up for a few seconds and cut out and now just cranking over. I’ve checked I’ve power to ignition coil but still nothing.
