280zinGA

Been surfing through some Z car sites and need some help getting a friend of mine's z running. I build mustangs so when presented with the z, my first thought was uh, wheres the starter solenoid?

I have searched through here and zdriver.com and found 2 threads close to the problem I have but it ended without them solving it.

The car is a 79 280z 5speed and has been sitting covered, under a car port for 6 years.

The car has power at key on (lights work, radio works etc) but when you turn the key to crank everything dies. I had the battery charger on full power and when you turn the key to crank, the radio or something buzzes and then something behind the passenger side kick panel clicks and then it stays dead for 4-5 seconds then will give power back to everything that runs off switched 12v.

I recently had the starter rebuilt so it isn't that. I hooked the battery charger straight to the starter posts and it still did the same thing.

I talked to a local z shop and they said it may be the main relay. They said sometimes the heater core is prone to leak after sitting for awhile and may corrode some of the wiring or ECU.

Going tomorrow to mess with it some more. Took the volt/amp meter with me and just about everything has 12v until you turn the key to crank . . .

Even the wires coming off the ignition switch.

thanks for all the help, especially since electrical help questions seem to be a staple among the z forums.
