Default 91 Fuel Issues

Hey guys

So my 91 was having issues with a bad hard start when cold.... shop said injectors, replaced those and nothing. Now, I can smell fuel in the cabin, and do not want to drive it anymore. Any ideas?

Check the vacuum line on the fuel pressure regulator. If there is fuel in it then the fuel pressure regulator diaphragm is ruptured.

Replaced the injectors with what?

What is your fuel pressure?

Is the pump pressurizing the injectors when the key is put to "run"?

Is the pressure bleeding off too quickly?

Is there fuel in the FPR tube?
