What happens when the fuel pump goes out on a Touareg?
There are physical signs that you can feel when your Touareg’s fuel pump is going out. Before taking anything apart, check to see if your engine’s computer has any trouble codes saved in it. The engine may throw a P0087 trouble code. This trouble code detects that the fuel rail/system pressure is too low.
What to do if your Touareg doesn’t start?
If your car isn’t starting at all, and you hear the fuel pump prime that is usually a good indication that the pump is working to some capacity. Testing your Touareg’s fuel pressure on each side of the pump would be the best way to diagnose this problem.
What does a priming fuel pump sound like?
Testing your Touareg’s fuel pressure on each side of the pump would be the best way to diagnose this problem. A priming fuel pump sounds like a high-pitched whine for a few seconds and can be heard with a sharp engine right after the ignition key is turned, but before the starter is engaged.
Where does the fuel pump go in a car?
In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s). It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do.
How can I tell if my fuel pump is working?
The only way to truly tell is to place a fuel pressure gauge on both sides of the line and get a reading from both. If your car isn’t starting at all, and you hear the fuel pump prime that is usually a good indication that the pump is working to some capacity.
What happens if your fuel pump goes bad?
One of the worst problems that can happen to a vehicle is a bad fuel pump . If your Volkswagen Touareg’s fuel pump goes bad, no fuel (or not enough fuel depending on whether or not it’s out all the way) can enter the engine. Without gas your Touareg will not run at all.

Why is the fuel pump in the fuel tank?
It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to.
Why does my car stumble when I open the throttle?
If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS). The TPS tells the computer how far the throttle is open. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture and when extra fuel is needed if the throttle suddenly opens wide.
