i have a 95 Z28 and it willnt turn over. you can turn the key and no gauages light up, the ony thing that comes on is the radio but no sound from the speakers. it die on me going down the road. it started iding rough then just cut off. anyone have any ideas what it could be?

 

First you need to verify battery is charged and will hold charge
Then if battery checks out test alternator. Also check your power block if everything tight
And not corroded


Start there first.

 

hook jumpers up to it and see if you get power, then if you can get it to start and run pull the hot battery cable, if the car then dies its a bad alternator

 

It could be ignition switch related.

Ouch! Don't ever pull the hot wire off the alternator while running
I know its an "old school" way to check if alternator but it is a big no no
Easiest way is to test it with a multi meter. While running probe the battery if you get 13- 13.8 volts then
Alternator is working. I have seen some charge a little lower but not less than 12.5 volts

 

not off the alt., off the battery it does the same trick without the shocking side effect, shoebox could be correct as well, also could be vats see if your security light is blinking as well

 

That was the next area but I'm slow lol

Btw on that topic have you ever seen a car have dead spot in the ignition cause
Of this? Reason I ask is I have to wait a few seconds or when alt gauge goes up else
Its dead if I just put key in and immediately turn it. Just wondered

 

The switch has sliding contacts, so anything is possible if it gets worn out.

 

Ok thanks. I was thinking key chip

 

thanks for all the input. i guess im going to have to try the ignition switch, evetything else checks out. im going to go over everything once again then dive head first into the ignition switch. thanks for all the help!!

 

She is alive!! thanks shoebox for that link. as soon as i changed out that switch she fired right up!
