Do not post the same question multiple times please.

And you need to provide some vehicle details: Year/Make/Model/Engine/Odometer

Thanks.

you most likely have an open in the ect wiring. when open the ect reads -40*...so the ecm thinks its a cold start and overfuels. can't elaborate further as you didn't include vehicle specific info
