Default Fuel problem

My car quit running yesterday, got it home and checked fuel pressure it was only 20psi, but I have codes saying both of my 02 sensors (I have LTs so I only have the 2) have low voltage. I am not sure if the pump is bad or if the 02s are bad and telling it not to send fuel? I had just filled up the gas tank 20 miles before the problem started.

Sounds like a fuel pump issue to me because bad o2s shouldn't make ur fuel pressure drop epically a 40lb drop

Yeah I didn't think it would. Its just weird, I filled up on gas, drove 25 miles to a ball game and it was fine, then when I left, it did not even go 1/4 mile before it started coughing. plus now it says my front 02s have low voltage. I just would hate to buy a new pump if its not the problem, I am going to pull the pump tomorrow and look at it, see if the sock is dirty or anything.

Well I pulled it out, and the rubber hose for the feed line down in the bucket had come off. so I am going to get some fuel injected hose and put it in and hopefully it runs

Good to hear u got it figured out seems like 80 percent of fuel pressure problems are related to the fuel line in the tanks. At least from everyone I've heard have issues
