Changed the starter in my 78 280z worked fine until I took it for a drive, one of the wires came off the starter it will not start. but show power to the gauges and fuel pump buzzes. When hook the wire back up nothing not buzz etc any ideas

Where does the other end of the wire go to?

If the end of the wire was grounded you might have blown a fuse when you tried to start, or when the wire came off, depending on which wire it was.

Considering the number of wires attached to the starter, "one of the wires" is pretty vague.

Sorry it is the wire that has the smaller wire, with a clip onthe end, that also ataches to the starter

That would be the solenoid wire. If it was touching ground (because it fell off) when you turned the key to Start you would have a direct short. There should be a fuse in the circuit somewhere. Check the wiring diagrams to see where that wire gets its power.

thanks for the help the little wire was easy to place the bigger one I'm guessing goes on the solenoid post that did not have a wire attached. Don't know how the bolt came off thanks again

The big one came off too? You didn't say that. There's one that has the battery positive and alternator charge wire attached and the other supplies power to the starter motor. Sounds like the one that passes power through the solenoid to the motor is off, based on your symptoms. But that wire is almost never removed. Maybe whoever put your starter together wasn't paying attention.

A picture would help.
