DME relay.
Cheap to replace and you should always carry a spare in the car.

Could be intermittently failing DME relay.
BTW, there are two types, a 15A unit and a 30A unit. These are the same right? Just higher amperage capacity in the newer 30A units? I was fooling around with my Motronics box on the weekend and decided to swap out the old looking DME relay. It worked fine, but since I was in/under there, I decided to fit the 30A unit in it's place.

"But I stop driving the car for six years."
This could mean a rusted fuel tank and rust in the fuel clogging the fuel filter. How long ago was the fuel filter last changed? Six years ago? Six months ago? |

Some how the car will start right up after sitting 2 or 3 minutes later.. But if I tried to start right after stall is won't start. To me is sound like the warm up start problem.. But I can be too sure... |
