Hi, I have this car since few years and it has 357 000 km on it. I took the car last week and it stalled on the road and wouldn't start after, the day after the car started and I drove it to somewhere else, After that it would start but stalls soon after or ran for a few sec and stalls. I had the car checked by two mechanics and they can't access the computer. One said the computer was fried and the other had no Idea. Some time the car will start and run smooth and the days after it won't. Does someone here had this trouble with this before or can someone tell me what should I check. I will not go at the store and replace parts I am not sure they aren't working.

Even if the scanner wont communicate with the computer you can still check if the problem is no fuel pressure or no spark or no injector pulse signal from the computer.
Follow the wire harness from the computer and look for a loose or dirty ground connection.Or the ecu might be fried.
