so i just bought an 85 camaro with the 2.8 multi port f.i. and i am now having troubles getting it to start....number one..my key switch turns alfully hard but has never been a problem in the past few months....now all i get when i turn the key is is silence...it draws down the power like normal but nothing happens and sometimes my lights will begin to flicker as i do this.....so far i have replaced the starter and the battery yet nothing seems to get any better...i have also noticed some clicking every once in a while when i try to turn it over...this was why i replaced the starter...but i then realized the clicking is comeing from up by the firewall on the drivers side...almost sounds like a relay but i am not for sure....if anyone has any helpful info on this rather frustrating issue i would really apreciate it...

thanks, nick
