Hi everyone, new to the forum as of today. I recently picked up an 05 passat tdi 2.0 that wouldnt start. The guy I bought it from claims to have replaced the fuel filter and couldn't get it to start back up. Any way I got it home took off the t hose in the filter and the filter was dry as a bone. I filled it with fuel, vacuumed the lines on the fuel filter, and proceeded to start. It cranks really fast and shakes the car like it wants to start, but doesn't. I squirted a shot of starting fluid just to see what would happen and it fired for about 5 seconds, so i believe its fuel related. Air in lines?? Fuel pump is working also, checked anti shutter valve, and egr aw well. I just cant seem to figure out what to do next, and cant find anyone who has had this problem in the past. Any help would be greatly appreciated, Thanks in advance.
