We have an AC school bus Tata make. We have been facing issues with the bus since last one month. Sometimes it fails to start, other times it stops while running. If we try starting it after 15-30 min or later, it starts without any problem.
For this issue we had called MG Motors, Rohtak. They send two technicians with a Laptop (charged 2500/-). After the diagnosis technician conveyed us that all electrical are OK and there is some problem with the injectors (2 nos. faulty) which needs repair or replacement. As this is a school bus so we were not able to take it at the same time for the repair. Again after some days it stops on the way and we called the technician again. This time the technician told us that the fuel pump is faulty. So we brought the vehicle to the service centre. To our surprise this time technician told us that ECU/ECM is faulty and needs replacement.
2 technicians, 3 check-ups and 3 different solutions by Tata with no guarantee of problem solution. These incidents clearly indicate that the technicians are not able to diagnose the actual problem.
You are requested to align the trained/knowledgeable technician from Tata to check the vehicle as soon as possible.
