have a 1992 Pontiac Bonneville SE with about 230K miles. The problem started about 1- yr ago. Initially it would happen on rare occasions, I'd turn the key and nothing just a clicking sound, I'd turn the key again and it would start right up. But for about the past year now it just kept progressively getting worse and worse with each passing day. It takes more than a couple of turns of the key to eventually get it started. Now it takes 20-30 mins of turning the key on and off before it will start, all you hear is the clicking sound of the starter but it wont start. All the lights and guages come on like normal. I took off the starter, alternator and battery (less than 6 months old) and took them to get checked at the auto parts store and they checked out fine. I checked all the connections, cleaned everything and still wont start. The only odd thing, aside from the fact that it wont start, is that on very rare occasions it wont even click and when that happens I notice that the Security light on the guages comes on and stays on even after I take out the key from the ignition. When this has happened I have to wait until the light turns off on it'* own and then I'll get the clicking sound of the starter.

What you describe sounds like corroded cables. You said you checked the battery and starter, but did you check the cables. You need to pull back the boot a bit and look. Corrosion tends to get in there as well. Also need to check both ends of both cables.
