1978 280z Fi Relay?

Alright, just wanted to say thanks for all your help, Never got the fuel pump working off of the stock harness, but ended up pulling the pump, and noticed that the strainer in the inlet line for the pump was filled up with gunk. cleaned that out and replaced the fuel feed line from the tank to the pump, and got fuel back to the rail. The next day the pump went out so i replaced it. Now the car runs, but misfires like crazy, and runs really rich (blowing black smoke), the car sounds like it has a huge cam in it. Pulled the spark plugs and they are all fouled, but the #'s 1,2,5,6 cylinders were really bad. Going to try swapping injectors, and see if that helps, is the fuel pressure regulator a common problem with these FI systems??
