guyz after you turn on the car( when the fan starts humming) and before hitting the sulf, the kit is supposed to turn on( green for cng or orange for petrol), but there is absolutely no light! and it doesn't start of course. but after many tries, there are moments where u get cng light, but the red dot keeps blinking along with green fuel lights. There are also moments when the switch is properly turned on and the car starts properly, but this happens after a lot tries.
Can anybody plz tell me what's the problem and how much the mechanic should charge for it? or is is simply some wire issue which i can fix at home?
