I have a 1992 camaro rs, 5.0 5 speed. I go and try to start it and I get nothing at all, not even the cranking of the motor. Then 5-15 minutes later I go out and it fires right up and runs like a champ. Any ideas is greatful. thanks will

could be an out of adjustment safety switch , or a faulty one that's operated by depressing the clutch pedal . Look up under the dash around the pedal , you should find it up there somewhere , see if it's loose and make sure it's engaging all the way when you step on the clutch. If it is engaging all the way like it should , the switch itself could be faulty. The next time the car won't start , hold the key in the start position and move the clutch in and out (which in turn will be working the switch) and see if she fires. Or simply bypass the switch with a jumper wire.

Car have VATS (chip in the key)?
