Sunfire injectors failure

Hello good morning.

Someone can help me, I have a problem with the injectors of a Pontiac Sunfire 2.4L automatic, these when lighting the car begin to throw gasoline, the leagues and filters were changed and it continues to do so, the fuel pressure regulator is already changed and it continues to do so, it will be necessary to change the injectors (3 and 4) or do any line be covered causing it to trigger more pressure than normal?
greetings.

I didn't understand anything, the injectors have to throw gasoline, now because you mean the three and four? Do they throw all the time? Did you try it in a test bank? Are those who carry the side or above? The Orrines are in good condition?

How kike grax for answering, throwing gasoline up the 3 and 4 are the injectors that throw gasoline and the injectors are new, they load the top and the Orrines are new.
Greetings.

The injectors are new or used, and of the type they are, they are the ones to press with a large staple that grabs all the injectors or it is of the KE type wears a rail of injectors above the injectors.

Then it is only for the cells or the gums are very narrow or when they were broken, or the rail is not well accented, I think it is nothing more than that, the orrines are put on or with bacelin or fat so that between soft and does not spoil, you will be existence to the ramp to rule out that it is released.
