It did seem to crank a little long before turning over when it was cold. Once it was warm, it seemed to start fine. This morning was very cold and it cranked but would not catch. I ended up running the battery down trying to get it started. It didn't take long so I think the battery may be weak. I can hear the fuel pump when I turn on the ignition for the first few seconds. Could a week battery possibly be my problem or is it fuel related. someone please advise. I've heard chevys have fuel pump issues.
