can anyone tell me where the starter relay is on a 1993(L) 1.7 non turbo diesel astravan? The van has an intermittent starting fault, it usually turns over and starts fine but sometimes it just doesn't turnover at all. I have checked the switch and it is fine(12 volts at the output ) So I think the relay might be the problem. When I find its location I will be able to check it as a process of elimination.
