Get it scanned and
Check ignition system.

Then ECT might be bad if it start working without it.
Bad ect can cause ecu to go in limp mode.

Does your car is heating up?
Have you done any work recently?

Fuel pump problem maybe

If the problem exist due to fuel pump why it give the same issue with CNG.

No it will not give issues with CNG if you fuel pump is bad... I will suggest to have the car scanned for error codes...

aziz.rehan (Rehan Aziz) 2021-03-29 12:46:17 +0500 #15

Because fuel pump is not responsible for delivery of cng only petrol

What is meant by error code

pwuser159371407082 (PWUser159371407062) 2021-03-29 15:57:28 +0500 #17

I discussed with several mechanics but no one was able to solve the said problem.

omersiddiqui5482 (omersiddiqui5482) 2021-03-29 16:06:57 +0500 #18

An error code is lodged in the ECT (card) of the car. when you connect a computer to the car with the OBD2 port it will show you the error codes which will lead to the exact fault...

I am very much sure it is an electronic fault...

Ok i will try this.let see what's happen
