Hello everyone, new to the club. I'm working on a 1978 280z and this thing has been sitting for years. So to start out I drained the fuel tank and put new fuel in, changed engine oil/ filter, installed new spark plugs & wires. All while I was waiting for a new ignition switch to show up. So once I got the ignition switch installed I started to crank it over trying to get a start. It wouldn't start so I took off the air measuring device and tried some starting fluid. It backfired on me. I verified I had spark at my plugs. I ended up going under the car and checking the voltage at the fuel pump while cranking and I had 0 volts going to the pump itself. Can someone help me out with wiring diagram and or description of up stream components to check from the fuel pump? (relays/fuses) and the location on the vehicle. Thank you all for the help and the add.
