Well yesterday my sister was driving our 98 K2500 and it died after about a mile. I am not at home right now but my dad is, we would like to get this truck going again today or tomorrow. We are pretty sure we have spark, otherwise it wouldn't have went as far as it did. The battery is fine, still cranks just won't start. We thought about the timing chain but I would assume that it might try to backfire or at least try to fire on a cylinder. This brings me too what we think it is, fuel. The pump runs but I don't think it is getting fuel. Any idea's?
