1997 pontiac sunfire, brand new battery, car wont start. cant even get it to crank when i turn the key. ive found various websites saying it might be a problem with the theft system. so far none of those solutions have worked. tested the starter at autozone and oreillys, both passed teh test. after putting the starter back in, the car turned on 2 times in a row, then went back to the problem of doing nothing.... any ideas?

any idea on how to check for this? any idea on how to check for this?

yea it can come in go sometime eventualy stopping for good. if you have a voltage meter you can check the output when you turn the key. you can also test the resistance if you can find out what the normal would be. if you dont mind the gamble you could just try to replace it. its only thirty dollars but it is on a list of alot of things it could be. you can also check to see if it is getting the twelve volt start signal goin to it if you have a voltage meter it would be the two small wires goin to it like i said it should be getting twelve volts to it. if its not getting the twelve volts then for some reason the car computer is not letting it start and it could be the theft system or some other problem like low oil or something. there are a ton of reasons why the car will not let itself start. yea it can come in go sometime eventualy stopping for good. if you have a voltage meter you can check the output when you turn the key. you can also test the resistance if you can find out what the normal would be. if you dont mind the gamble you could just try to replace it. its only thirty dollars but it is on a list of alot of things it could be. you can also check to see if it is getting the twelve volt start signal goin to it if you have a voltage meter it would be the two small wires goin to it like i said it should be getting twelve volts to it. if its not getting the twelve volts then for some reason the car computer is not letting it start and it could be the theft system or some other problem like low oil or something. there are a ton of reasons why the car will not let itself start.
