OK, I realize this could be a thousand things, but you guys were spot on helping with the a/c problem i posted a few days ago, so just wanted to see if there was a common problem you all knew about. Here's the deal, this has been happening for the last 3 weeks. Go to start the car and it just cranks, over and over without firing. I thought it was a ground because the fuel gauge was jumping to full while trying to start. Next I checked for spark, nothing. Checked fuel pressure, almost none. So no fuel, no spark. Came back a few hours later, started right up. Two weeks later, same exact thing, left overnight, started right up! What do you all think? Gonna have to get a diagnostic probably, just thought I would check. Thanks.
