Angry Need some help

I have been helping my friend get his car running right but it seems like every time we fix something on it something else goes out. I'm getting super frustrated at the car and need some help. First off the car isn't a fbody but it is an lt1 equipped Buick Roadmaster. He brought it to me running rough and it being an lt1 i figured it was the opti, plugs and wires. After changing them the car ran great so he drove it home. the next day he calls me up and says that he is having issues so i told him to come back buy so i could have a look at it. he got to the gas station by my house and called me saying that he couldn't steer the car. I went to look at it and the belt was thrown off. I replaced it and had him start it. when he did i noticed the PS pump pully wasn't spinning so the PS pump got replaced. A day after that the car was running like crap and the battery wasn't getting a charge so it got replaced and took it for a test drive. the car was still sputtering. I tested the fuel pressure and it was at 20psi so the fuel pump was replaced. He drove home again and wouldn't you know it the next morning the car starts, warms up then cuts off. I tested the fuel pressure today and it was at 0 so the relay was replaced and it didn't help. Oh the fuel filter was replaced about 2 weeks ago and when tested today it looked good. I can hear the fuel pump when I turn the car on but there is zero pressure. Did I miss something? Any help is appreciated.

You could have a pin hole leak on the fuel pump outlet hose, or maybe the hose popped off all together. If you can hear the pump prime with 0 fuel pressure that's all I can think of. I'd say get back in the fuel tank and have a look.

Turns out the line between the pump and the sending unit was kinked.. easy fix and the car purrs like a kitten.
