So I went to the shop to have my cat replaced because everything else checked out. This time they checked the fuel pressure. The pressure was 47lbs and is supposed to be at 50-53 is what they said. My guess is fuel filter. The regulator is made into the fuel filter. What do you guys think? Car runs great very smooth .
my actual cause of p0420

How did they verify that everything else "checked out"?

I think he probably meant to say that the regulator is part of the in-tank fuel pump/regulator/filter module.
No I meant the fuel regulator is in the fuel filter and it is. Its a Saturn sl2
Saturn put all the fuel stuff in the tank in 1997. If you had a flow restriction like from a bad filter the pressure would go down when you get on it. If you don't, pressure will go up, as it needs it to rise so the injectors fight the lack of vacuum. This is why they used to have vacuum-tied pressure regulators on fuel rails with return systems.
I think these mechanics are looking for a cop out so they don't have to fix your cat again. If they can't sell a part that meets EPA specs they need to stop and buy better stuff, or they'll get comebacks like you.

The fuel filter isn't in tbr tank I know that for a fact. Its on the bottom of the car and the regulator is built in
Gm says the pressure should be around 40-55. So 47 is cImpletely nornal . I'm getting extremely frusterated. The kid that works there was like all I've owned is Saturn's blah blah blah. I honestly don't care I just want my car fixed.
Cats can and do go bad. There is a good chance that this will fix it.
I know but the shop doesn't want to do it now.
They were hoping a 14 year old car would bring them some diagnostic work. It's in good shape. Read the warranty on the receipt you have and, well, throw a fit.
You must look like a "mark" being a young dude. Don't give up. Say you spoke on the phone and were promised a new cat and you're not leaving until you get one. Block a bay door and be a jerk, whatever it takes.

I'm going down there again in 20 mins. Ought to be fun
someone may end up getting an attitude adjustment . Believe me I don't mind giving one. I hate being lied to!!
The boss wasn't there I gotta go back at 5. You do that o2 extender?
Earlier I had said that you found an honest and decent shop. Obviously this development shows that is not the case. I was actually surprised when they said they will replace the converter.
So far I am running two out of two
Put the O2 extender and spend your free time with your two year old. Play with him and put your truck/car trouble on the back burner.
