I have Maruti 800 Bharat 2 car. It did not get started, what should I do ??

I have a maruti car. It is 2003 model. It is Bharat 2 with MPFI engine. It does not get started. One mechanic told me that the car has problem with its ECM (Electronic Control Module) unit. Please advise.|||Check if the battery is down. If its fine then better call up 24 hr helpline of maruti. That should be a safer option, than calling a road side mechanic, after all you have put some money in it and you should not loose it.|||The battery of car may be down/ defective.Start the ignition ,keep car in second gear, press clutch tell someone to push the car as soon car gains some speed release clutch. If the problem is with battery then this way car will start.If car does not starts then there is some other problem Check Fuel Pump also
