ok so i have a 93 eg si. it will not start without a boost but as soon as you boost it it starts right up. but when i put the battery on the charger the charger says that the battery is alredy fully charged. and then when the battery is hooked up again and you turn the key on somtimes all the lights ect. will turn on and work perfect but then you try it again and nothing will work and the dome light will be a dim and blinky and then you try again and everything will work fine again. but nomatter what the car wont start like it wont even turn over it just makes a click sound and everything dies helppp

 

Wow. Check the starter.

 

i thaught that at first to. it ended up being the battery it went all wierd and acid came out off it, threw a diffrent battery on and it worked fine
