I need located the Fuel pump relay I just installed new fuel pump but the car is not having the right fuel pressure its 1998 Audi A4

hi
have you check the starter motor. it might be stuck.

Use fuel pressure gauge to test pressure with key on and while running. Low or no pressure can be caused by bad pump, relay, filter, regulator. No pressure = bad fuse, relay, pump, maybe rollover valve if you have one. Your car may also have an ASD system.

Take off the lower dash panel below the steering column. The fuel pump relay has the number 372 on it.

the fuel pump relay located central electric panel, in E box, footwell front right (relay J17) position #6.

Behind left side of dash in 9 pin relay carrier.Relay #1 . There are 2 rows, top row 789, under that bottom row 123456.

Should have mark behind the relay box cover stating what relay to what, there additional relay also located under floor panel.

Hi there again

Sorry to hear you are still having problems.If you are going to change the pump I would certainly not recommend you do it yourself.If it is the V4 motor I am thinking of, you would need to get to it by removing the rear seat ,remove access panel , and pretty much play around in the gas for an hour or so to get it off in the first place.

What I did find was this on the net on a recall by Audi to replace 2002/03 model fuel pumps as noted below.

RE: 2002 Audi A4 Fuel Pump Change:


I just had my fuel pump changed out by the dealer. Here is what the letter said-

"Safety Recall JL 2003 year Audi A4 quattro with 1.8L Turbo or 3.0L engine and 2003 Model year Audi A6 with 3.0L engine"
The fuel pump on some affected vehicles may contain a carbon brush set that is susceptible to premature wear.

On invoice it says-

JL12 Install fuel delivery unit and sealing washer.
1 8E0-919-133-G Washer
1 8E0-906-087-P Fuel Pump

No charge for unit or install. Just call them up and give the vin number to see if your car is affected. On the other note of your code error '1&3 misfire',try and have it re-set (it might be an old error)and see if it comes back. Hope this helps ,and I will research your problem further with pleasure if need more help.

if you have diagnostic equipment you will be able to see the signal through serial data(if you believe it)the cranksensor is located near the rear of the engine pointing towards the radiator i think it goes to a grey plug....

P0130 is 02 sensor bank 1 and P0150 is 02 sensor bank 2.
