My 2010 2.0 litre Diesel A/T is 15 months old and has less than 500 km on the odometer. Shortly after buying it, I broke my wrist and until now do not have full use of my right hand. Since resuming driving I have been using a smaller car. For these reasons, the Captiva has only had infrequent outings and regular warm up sessions. Yesterday I wanted to start it and the engine only turned over once. I assumed the battery voltage could be low, although it showed 12.4 volts. I charged overnight and the voltage was higher and the headlights very bright. However trying to start produced the same result: turned over once and then stopped even with the key held to start. I noticed that prior to each retry, the glow-plug lamp did not come on. I disconnected the battery in case a reset might correct the problem, but except for requiring the radio code there was no change. I assume it is a sensor, electronic glitch, or other electrical problem. I checked all the fuses and relays etc. in the front and back fuse boxes and all seemed ok, but still have the same problem. I don't have a wiring diagram. Any ideas on what to look for.
