Ok time to ask for some help from the experts on here, you guys have seen or heard just about everything. I have an 02 TDI Jetta that will not run more than lets say 20 minutes, exactly when the fuel filter is emptied. I have replaced the fuel filter and same thing it will run aslong as trhe fuel filter has fuel then it will not refill the filter and stalls out for lack of fuel. I have replaced the injection pump about 5K miles ago along with new fuel injectors and nozzles. Any help here would be greatly appreciated.
