Turns over but that's it!

[CJK '73 240z]

HI All,

I have posted re: this topic before but still have not had success firing up my '73 240z (9/72). When I turn the key the engine will turn over but will not fire. It will fire briefly with starter fluid but only runs for a few moments. I hear intermittent clicking from under the dash but that's it. I have checked the fuel lines and there is no fuel coming from the fuel pump. The fuel pump may be the problem or lines or tank... but other problems lead me to believe that there is no power runnning....well ...anywhere. The only power I have while the key is on is to the starter and to the headlights (no signals, radio, heater, interior lights, brake lights... nothing). I have replaced the fuse box but still no success. I have been told to check the inline fuse but am unable to find it. If anyone has any suggestions please let me know - in layman's terms please :nervous: Thanks!

Lets try this again. When the engine is turning over you should have gas flowing to the carbs. Your Z should be equipped with both electric fuel pump and a mechanical one. Information : when you turn the key all the way to start. the power is 12v to the coil and when the key is let to the run position it then runs on 8v. So if the engine is trying to start and wont continue. You need to check the ignition switch . You were told this before . The actual switch is the part at the vary back of the complete switch where the wires are plugged into. If this switch is bad this could cause the electric pump to not be energized also. The electric fuel pump should have power ,the green wire, check it near the gas tank and see if you have any power there in the run position.
