Fuse 6 (20 Amp) brings power to the fuel pump relay. My instructions say the fuel pump relay is in the fuse box behind right hand side of instrument panel, but an illustration shows it on right side of dash. (The relay is by it self on the fuses side of the fuse box).
Fuse is in same fuse box.
Sometimes if you don't use a car much and its an older car the fuel pump may seize up and not work properly. Check the wiring and see if you have power going to the pump . If you have power the pump is at fault.
You can check the wires with a tester for 12 volts with needle type probes that you insert into the wire its self.
really need motor size all 95 and up audi use vw fuel systems I have included fues box diagram # 18 is fuse for fuel pump power and # 12is fuel pump relay I could not find a fuel cut off .
Start with checking your fuel pump and injector mini relay. Fuel pump relay is #18 and injectors is #48 and is located in the fuse box under the engine hood.
Also inspect your ECM fuse, the fuel pump get's it power from the ECM fuse and at wost. It's your fuel pump that has gone bad and that is located in the gas tank, but make sure your fuel filter is not to dirty causing fuel restriction and replacing that will address that issue.
Thank you for using fixya and keep us posted.
Power for the fuel pump is supplied by fuse #16 in the Power Distribution Center (PDC), goes through the Fuel Pump Relay and then to the Fuel Pump and the ground completes the circuit. Power for the Fuel Pump Relay coil is supplied by fuse #18 in the PDC and the Powertrain Control Module (PCM) supplies ground. It is a fairly simple circuit to check.
The first thing to do is check all the fuses, especially #16 and #18. If you have they are good then you will need to pull the fuel pump relay and check for power, with the key ON at the dark green/black wire and orange wire. The DG/BK wire is the power for the fuel pump and the OR wire is the power for the relay coil. If you have power there connect a jumper between the DG/BK wire and the dark green/white wire. You should hear the fuel pump running. If not there is a problem in the DG/WT wire from the relay to the pump.
Okay, lets assume that checks out fine, the next thing to do is replace the fuel pump relay and ground the dark blue wire. You should hear the fuel pump running. Okay? Good, now go to the PCM located on the firewall in the engine room. It has three large connectors, black, white and grey. There is a DB wire in cavity 19of the grey connector. Ground this wire and you should hear the fuel pump running. If it does then the wiring for the fuel pump circuit is all good and the PCM will need to be replaced. If it doesn't run, then you have a problem in the DB wire between the relay and the PCM.
The power to the fuelpump comes from the ignition switch to the pump check for power (testlight lights up) with the testlight clip grounded at these locations.
to check the fuel pump it's self:
use a 20 foot long 18 gauge inline fused test wire from the positive battery post to the pump
