I have 96 A4 AQ and yesterday started the car and it ran for few seconds and then engine stalled, fuse is ok and i held my hand over the relay and felt click, the car has not been driven for few days and there have been no symptoms before. Might need try check volts from pump connector before i start taking whole pump unit out from tank.

We are not hearing any noise from the pump when we start the car

Hi there, is the car starting or just turning over and not firing up? If it's not firing up then check for power at the fuel pump with the ignition switch on.

Any idea for a 2008 a4 3.2L? I’ve pulled every relay in this location and the engine keeps running… Does this model have the fuel pump control module? Thanks in advance

Hi there, it's been a while but the relay should be in the engine compartment/ firewall. If you still have trouble locating it I will be back in town next week and I'll pull the pinout and flow so I can tell you the exact relay. You can also remove the lower rear seat cushion and unplug the pump wire harness. The pump will be located under the access cover. You will see the access cover upon removal of the seat.

@@dewitech2358 So in the module box under the hood? I tried to remove this yesterday and there is a screw that is way in the back, looks like I need to remove the wipers and cowling for access? I did access the fuel pump yesterday as well. There is no pump module located there like I've seen in some other videos. I have known from other manufacturers that if a fuel pump control module is present, that usually takes the place of a fuel pump relay. But not sure on Audi's. I'm trying to replicate an issue of fault code P0190 for the fuel pressure sensor. I believe I have a bad low pressure fuel pump, but trying to get some diagnosis on it first, and make sure it's not a relay or control module. (Dies while driving, and has a long crank) Thanks.

Hi, from your description of it dying while driving and long cranking before restarting I can say it most likely is the fuel pump. Pump is getting hot then shutting down or is losing continuity. A simple means of diag would be to test for power at the pump when it dies. If you have power but the pump doesn't power on Bob's your uncle.

@@dewitech2358 Awesome thank you. And your talking about the low pressure pump correct? I was thinking the same thing. I tested the internal resistance from the 2 smaller/middle pins yesterday. It reads 118 ohms which sounds extremely high to me. But it was also running perfectly at the time of testing. Can you verify for me what pins go to the pump windings? And what the resistance of the pump should be? Thanks.

Hi, sorry so late with a response. I would suggest checking for fuel pressure at the rail. If you don't have pressure then the most probable cause is the fuel filter. If you have fuel pressure then check for ignition spark. Spark at the plug should be you starting point. If you have no spark at your plugs then it can be caused by a few things. Have you tried scanning for codes?

If it's not cranking it's either a battery issue or bad starter motor, check out related wiring and connections between battery and motor.
