my friend's 87 740 seems to have a random no start. i checked it out tonight:
i turned the key to ON none of the lights came on in the dash. i cranked it, but it just sputtered and died immediately. i turned it OFF and then back ON, and then i have lights. then i have all the lights, i crank it, and it runs fine.
this seems to have come on with the extreme cold lately. otherwise the car has no running problesm, very smooth and plenty of power, so i've ruled out ignition and fuel. ignition switch?
