Flashing check engine light.
1998 F150
5.4
159000 miles
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.
