How do you check for leaky fuel injectors on a v6 motor? You don't have to remove the entire fuel rail do you? Can you remove one at a time and have someone turn motor over and do a visual?

 

Best way is to have them profressionally checked.

However, you can buy a fuel guage, run the car for a minute, leave guage on and go out every hour and check it. If it drops majorly fast to 0, you have a leak SOMEWHERE. If it drops only like 10psi over night, I say thats fine and nothing to worry about.
