a fuel filter replacement is a verygood thing to do especially in these type of cases. Alsosome of these trucks during that model year would seem like a failed fuel pump which it did, but you need to get a correct delco one tat includes teh 12" of harness that goes bad and has to be replaced. Especially if you have replaced the fuel pump recently....
