A.A , I'm facing this problem from last 4 days , cultus 2009 efi is not starting up and produces firecracker sound suddenly. But sometimes it starts automatically producing no sound . Please tell me about its solution , thanks
I think the plugs problem. Change the plugs. Rest the experts can guide you better.
Does the MIL blink during the firecracker sound?
try starting it at night, look at the coils in the darkness
check your spark plug's
check your distributor timing
