The vehicle will have to be cranked a few times to get the bad fuel out of the far end of the fuel delivery systemif you have a safe way of collecting a sample from the fuel rail (like a fuel rail test port with a green cap) you can take samples there by switching the ignition from off to run several times until the fuel is clean.

You probably have a clogged fuel line or fuel filter. I'm not sure what you're referring to when you say fuel filter regulator but I'm guessing you mean pressure regulator for the TBI. Tear down TBI and give it a good cleaning carefull not to scratch or gouge anything.
