Im trying to get my IROC going again but during a cold start theres ticking on the driver side and white smoke during start-up then it goes away. Also theres a strong smell of exhaust/fuel but cant find any leaks on the vacuum/fuel lines. I recently replaced spark plugs (AC Delco 41-905 Platinum Plugs) installed taylor spark plug wires, and had mechanic shop install edelbrock TES headers. Help !!!!????

 

Any updates?

 

Did you recently get the fuel pump replaced? You could try filling up the gas tank and seeing if your gas tank leaks gas. I brought my Iroc in a while back to get the fuel pump replaced since I was way too lazy to do it myself and they cracked my tank. Also check the gas cap and make sure it doesn't need to be replaced. And how much white smoke is it? A little bit is alright since it could just be moisture. If its a lot of smoke the valve guide seals might need to be replaced.
