AOA,
Experts I am facing a problem in my car, my car running fine on CNG but on petrol its missing or say not run at all. i went to the mechanic and he said that this a injector issue and replaced the injector But it didn't work. then he told me that it is your Fuel issue as your fuel pump is weak and doesn't have much pressure.. i need to know how to make sure that its a fuel pump issue, as i checked that fuel pump was able to give petrol but i don't know the what pressure its required. or i have to check other things as well?
Your guidance in this regard is highly appreciated.
