problem with wiring

i have bought a '84 300zx last month. i have been having problems with all of the lights on the car. i thought it may be the alarm being installed incorrect, so i cut it out and reconected the original wires. well, now i'm not getting any power to the coil or the fuel pump. anyone have any ideas what the problem could be or maybe have a wiring diagram? delarosa74868@yahoo.com
