ok my camaro is not firing and it statred doing this after i took it off and put it back on so if u have some advise please let me know

 

Do you mean the engine will not start at all? Does it attempt to start at all, perhaps with some backfiring? Has it refused to start since you removed and replaced the distributor?

If so, you may have assembled the Opti incorrectly, with the cam dowel pin in the wrong hole in the back of the Opti.

Why did you remove it? What did you replace it with? Are we talking OEM replacment, or some other brand?

The more info you can provide regarding what you did, the sequence of events, etc, the better chance we can help you. One way of including more info in your posts is to add a "signature" with basic info about your car - year, model, engine, tranny and any major mods. That way the info is attached to the bottom of every post, and is always available.
