Wagon. Where is fuel pressure relay switch? - 1998 Audi A6

Subaru vehicles do not have inertia switches. That is a Ford item. Your fuel pressure tested good then? Those have main relays up under the dash on the far left of the drivers side, sometimes those do go bad. Your 2004 should have a fuel filter on the left strut tower, if it's never been changed that could be the problem too. I have seen fuel pumps work but the level sender go bad and say there is fuel in the tank when it's actually empty.

As Steve said you need the fuel pressure checked . The cooling fan can be the coolant sensor, relay, fuse, wiring, connection or fan motor . Does the fan run with AC switched ?

The PCM - engine computer will energize the fuel pump relay for two seconds with the key , When cranking the engine the PCM will only energize the fuel pump relay if a crankshaft position input is seen . An testing fuel pump pressure should be done with a fuel pump pressure gauge only .

Don't worry about it...as soon as you loosen the fuel filter clamp the pressure will go away. It's not that high. Just wrap a rag around the connection.
You can also pull the fuel pump fuze with the engine running...when engine stops the system is depressurized.
If it has a mechanical fuel pump (?) there will be very little pressure if any in the system.

Hope this helps

the Daewoo wonder wagon, in snake clothing.
and 6 engines, ill guess at gasoline engine.
so what makes you think there is one, (hope:? dreams, rumors?)
you have zero fuel pressure, is that it? did you check that first?
got spark?
run on test fuel? yes then
do you have 12vdc top the pump cranking> yes/no,

there is no electric fuel switch, period, only the Std, fuel pump relay
that PCM operates only.

that leaves fuel line switches (inertial fuel valves, real name)
and the fuel diagram, shows, no such part.! it's not there, in USA car
is it a USA car?
so you are guessing.?
thanks for the goose chase. what a waste.
why not , post the symptoms and get real DIAGNOSTIC help
and avoid this goose chase.
what's bad is suzuki online parts , suck they have no online drawings.
do you want go Guess, or test.
do say.

If you were not hit hard in an accident, I doubt the
switch opened

Look around the side panels near the front doors
or google the question

You can buy pass most of the fuel system by going right
to the fuel pump relay & jump the terminals with the relay out,
to test the pump & fuel pressure at the motor

I don't think the EFI relay is at fault. Other things would be dead if it was, including the starter. See here p177 to test fuel pressure, which may be too low if the fuel pump itself or the pressure regulator is faulty.

you must remove the fuel tank. see procedure below.

The fuse and relay should be in the engine compartment relay box. Check fuses 2 and 14. The relay might be labeled PGM-FI

1988-91 MODELS

The fuel pump is located in the fuel tank.

1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure.
3. Raise and safely support the vehicle.
4. Remove the fuel tank drain bolt and drain the fuel into a suitable container.
5. On Civic models (except CRX and Wagon) unplug the fuel pump electrical connector in the trunk. On CRX, remove the storage compartment and unplug the fuel pump electrical connector. On Civic Wagon, remove the rear seat and carefully disengage the fuel pump electrical harness.
6. On Civic Wagon with 4WD, remove the driveshaft from the rear differential and the exhaust pipe and muffler.
7. Remove the 2-way valve cover and fuel hose protector.
8. Unbolt the fuel lines.
9. Place a suitable support under the fuel tank.
10. Remove the fuel tank strap nuts and let the straps hang.
11. Remove the fuel tank.
12. Remove the fuel pump mounting nuts and the fuel pump.

To install:

1. Install the pump assembly into the tank and make sure the unit is properly sealed.
2. Install the tank into the vehicle and tighten the strap nuts. Connect the hoses and wiring.
3. On 4WD vehicles, connect the driveshaft and the exhaust system.
4. Put about three gallons of fuel into the tank and test the system.

The fuel pressure relay in the engine is not working or the fuel pressure relay is not working .
Try to replace the fuel pressure relay or soleniod in the engine area.

IF this does not work , Check the timing of the engine.
