Re: canot get car started. no fuel is coming to engine.
Well since the car was sitting for a couple of years its important to drain the old gas and change the fuel filter. The gas starts to turn into varnish which could and almost always will gunk up. by doing these your system will be clean

Year make and model ?
Have you swapped the fuel pump relay with another ?
Its normal for the traction control light to come on if the check engine light is also on.
Have you checked the engine computer for trouble codes ?
take the spark plugs out and fill the water up. turn over the engine. see what comes out of the spark plug holes. should just be fuel. smell. you will need some one to turn the engine over and have good charge in the battery. fill the water to the top so it is level. if you see the water go down when the engine is turning. then it could be air or a leak in the head gasket.
This could possibly mean a few things..
1) Flooded engine
2) Spark plugs/wires need to be changed
3) Dirty fuel filter
4) Inoperative / intermittent fuel pump
5) Bad gas in the engine or gunk in the engine
Do you have any lights that come on after you try to start the car (i.e. check engine?)
Turn the key to the 'On' position, but don't start the vehicle.
Do you hear a whirring noise coming from behind, or underneath you? If you do, then the fuel pump is working, or should be. There should be a whirring noise for a few seconds when you do this.
The way the fuel system works on this vehicle is that when you turn the key to the 'On' position, it should start pumping fuel to the engine. But it is not pumping the fuel directly into the engine, it is just pumping enough fuel to generate pressure in the fuel lines. The fuel comes back to the gas tank from the engine due to that pressure.
I would recommend that you get a Haynes Manual #24071 for your vehicle and look up the section on the Fuel Line. There is a way to test the pressure without removing the hoses/pipes which go to the engine.
I don't believe any VW sent to the US in the past 15+ years has come with a plug-in heater. The only exception is if the car was from Canada, or if one was installed afterwards.
If the engine turns too slowly to start, try cleaning the terminals of the battery, if still nothing- replace the battery.
If the engine turns over but just won't fire up cycle the glow plugs a few times before trying to start. Turn the key to on, wait for the glow plug light to go out after a few seconds then turn the key off. Repeat 2 or 3 times before you try to start.
Also make sure you use a fuel additive for the cold months. Look for something with anti-gel on the label.
You may need a new ECM/computer. This model car is known for water leaking into the ECM from your air box. The drain hole in the bottom of the box gets clogged and after a while, your ECM gets flooded, because the water has no place to go, but onto your ECM, frying vitale circuits. Check your passenger side floor by the feet to see if its wet.
