My 1999.5 Jetta TDI died one evening as I was slowing down for a stop sign and would not restart. I have checked all the usual items, relay 109, anti shutter valve, timing belt, changed fuel and air filter... It doesn't seem to be getting any fuel. I have about 1/2 tank of fuel from a fill up 4 days earlier. I am not getting any error codes. Any ideas?
