Want this question answered?
takes about an hour you access from under rear seat.. unit fitted to fuel tank...check FUEL PUMP RELAY first ....
Fuel pump relay Audi a4? what is the question? does it have one? answer:yes, where is it located: under steering wheel to right. need to remove panel. its the relay on the right.
it may be in fuel tank,but first check fuel lines and see if it's along the frame. they seem to go out.
A 2005 PT Cruiser does have a fuel pump relay. They have a fuel pump relay rather than a fuel pump switch. The fuel pump relay is located in the fuse box.
The main relay and the fuel pump relay are the same. Take the fuel pump relay and swap it with the main relay and see if that will help you....
If the relay is bad, then the fuel pump will not work.
Yes, it is a fuel pump relay.
I can't tell you for sure because I never had an Audi, but since it is electronically fuel injected it would have an electric fuel pump... If your pump is not totally dead, you should hear a humming sound when you turn the key forward a click (not to start the car just to accessory) that sound would be your fuel pump turning out and pumping gas to your engine... My guess would be that the fuel pump is in the gas tank... if not, just follow the fuel line from the tank towards the engine and somewhere between the two will be a fuel pump... Hope this helps!
Bypass the relay and if the pump works the relay is bad.
Bad relay, No power to relay, Wiring from relay to pump and our most likely problem is, the fuel pump is bad. changed it already
The fuel pump relay switch looks like the normal electric switch. The function of fuel pump relay switch is turn the fuel pump on.
Swap the fuel pump relay with another like relay in the fuse/relay center. If the problem with the fuel pump goes away, the relay was bad. If not, knowing GM fuel pumps, the fuel pump is the problem.
