try to start...click....nothin else....what would this be...the battery is fine...

Starter, cables or connections

what cables? or connectons...? also sometimes it will start and ill get the crank/cam error...cam sensor or crank sensor????

Cam and crank sensors won't keep it from turning the engine. You have a starter problem. Either the ignition switch, starter, or wiring/cables.

Crawl under the car with a large screwdriver with a rubber handle. Look at the back of the starter, there are two connectors with two wires, one large one small. Use the screwdriver to carefully bridge the two. You'll see large sparks and hear a bunch of noise, you'll think you're breaking it. Don't worry, its fine just be careful not to shock yourself. If it sparks and only "clicks" then its your starter. If the car turns over come back and I'll tell you a few key places to look for grounding problems.

on second thought if it clicks it could still be a ground problem...uhm...try that, see what happens. I'll post more later, I gotta run now

what is part number for starter?

For a starter, you're better off just heading to the local parts store. If you have the old one out, bring it with you to save on core charge.

The click is the solenoid engaging. If nothing happens beyond that point, it may be that the cable connections are bad, and are not drawing enough juice to actually crank the starter. Before replacing the starter, clean up the battery cables at _both_ ends (i.e. especially the hard-to-reach ends where something may be either glopped-up or loose).

Your cables should be flexable if they are stiff they probably have corrosion under the coating and need to be replaced. Alot of people over look the battery cables.
