I have a 98 cobra that I don't drive a lot anymore because of a company vehicle I have. I went to drive it today and it wouldn't start. It would turn over fast and act like it wanted to fire, but it wouldn't. Then I decided to pump the gas pedal, and it started. Any ideas might cause this? Is it because it sits a lot now? Also there was a little white smoke coming out of the tailpipes for a minute. Thanks
