i have a 75 280z and when i hook the battery cables up the starter turns over automatically. not sure of problem can anyone help.

 

Welcome to ZDriver!

Is the key set to START?

 

Um did you put the + cable on the proper side of the starter?

 

Ah... that would do it.

 

thanks for the info i got it to work but the ignition isn't working i bought a new ignition switch and it didn't help. when i turn the key over nuthing happens any answers.

 

Have you checked all your fuses and fuseable links? Also making sure the signal wire to the starter is connected?

 

fuses are good but i am still having a problem. i can turn the car over with a push button and i am getting power up untill i get to the ignition. evrything turns on with a push button but the ignition wont work any ideas?

 

When you turn it over that way you are by-passing the ecu and ignition which are turned on with the key. There are two wires coming from the battery to the ecu. One + and one -. When you turn the key on you should hear a click from under the dash. If you hooked the battery up wrong then you may have fried something. Buy an inexpensive muti tester, download the FSM from xenons30, (donate $5) and start checking everything. If you get stuck post it.
