Not very wise to assume the check engine light came on for no reason. The way to avoid disappointment is to always expect the worst. The light is on for a reason and there could be a fault code stored and you need to know what it is for future reference.

It is true it is usual to initially cancel the code and see if it recurs...

I am not sure which diagnostic reader is suitable but I hear Indian stuff has slightly different electronic systems to everyone else though common to South Asia.

I suggest you check in the handbook to establish the precise function of the (flashing) engine light and then ask around for somebody local with suitable software/diagnostic equipment...

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

Any engine can be put in any vehicle if you have enough money and time. The better question is does this swap make sense. I have no idea as to that answer. Sorry.

You most likely have a vapor-lock problem in your fuel system,or possibly a clogged Fuel Filter. There may be trash in the tank if the filter is bad, replace it. Check to see that the fuel-tank cap is closing well. Check the Air Filter also it WILL effect the way the engine runs I'll need more information to speculate further, too many relevant facts missing in your question. Try to include everything Thanks!

First check there is power reaching both devices. Use a multimeter to check for power. Should read 13 volts approx. Check fuse and connections ..... If that is OK, then its the float or dial. Replace.
