My truck broke down sat for a few months it's old. It's got 260k miles I think it's a fuel problem but not quite sure. I changed the fuel filter one afternoon and it fired right up seven times in a row. But it won't start in the mornings. I get home after work starts right up. I think it has to do with the cold but it's been around 40 degrees in the mornings not to cold. It cranks but won't start.
