hi

checked the ground as per your suggestion and everything was clean and in good shape.
what else can be the problem?
why it seems that there is an electrical blockade when the engine stalls?
what is causing the system to go blocked?
last time when the engine stop i was adviced to disconnect the positive terminal from the battery for few minutes and connected it back, then it seems that the system was reset and the engine started. The problem is that it is happening frecuently and i beginning to not trust the car.

Disconnect the battery cables again and pull the boots off the cable ends. Tell us what you find (along with 11 other members here a month, I bet you find a surprise).
