Hi all, I am new to this forum and to Z cars. I bought my 1982 280zx non turbo from my neighbor who had it rotting away in his garage. I started with the motor, got it running by basically running through and replacing all of the obvious things like; injectors, plugs, plug wires, air filter, fuel filter, water pump, radiator, thermostat, any hoses that were bad, computer, coil, cap and rotor, and so on. I had this thing running perfect so I moved to the inside and completely restored it. Long story short I was getting very close to being finished when I noticed fuel leaking from the rear of the car. The leak seemed like it was coming from the fuel pump so I decided to replace it as well. I thought this would be simple which it was BUT........now the car runs horrible!! Bad idle, horrible acceleration, black plugs, I can barely keep it started when I let off of the gas, and it all started after I changed the fuel pump. I thought maybe I got a bad pump from O'Reilly's so I ordered one from Z car source and got the same result. Like I said, this is my first Z car so I'm learning as I go, any help would be appreciated because I'm all out of ideas.
