Ok so I've had my check engine light on here for about 3000 miles, ran the numbers took it in, it was a bad bleed valve on my fuel pump. However at the time I didnt have time or money to replace it so I was waiting till next monday. Well on my way home the check engine light started flashing so I turned it off, opened hood, let it sit then started it up and it stopped flashing.. What does this mean? As of now I am no longer driving truck till I get the problem worked out.
When the CEL flashes it means the problem is immediate, as opposed to vacuum leaks, misfires or dirty sensors that set a solid CEL. Either way you need the codes pulled before we can say what the problem could be.
