Please help we've been trying to figure out what's causing my jetta to not start. This all started when I was driving home I stopped at a red light when it turned green as I was pulling out to go I felt ut sputter couple times and than lost power I pushed down on gas pedal but there was nothing. Lije it had no pressure at all and my car died out. Tried to start it but wouldn't start. We had it towed home. I've had the glow plugs changed fuel pump and filter changed we weatherized it. Shot carb cleaner into see if it would at least try to turn over but it didn't so we ruled out anything to do with the fuel. Need help any ideas what it could be or what else we could check on that would cause it not to start. Its got crank but no start. Please help with any ideas.
