That was a great step-by-step tutorial on the replacement of the fuel pump and filter. That pump looks pretty snug and probably the special tool would be a good idea to have for this job. Nice work Thomas!
2003 A4 3 liter will crank - no start when cold outside - -5c ish. When the car is in the shop overnight it will start. ( most times) Checked fuel pump and seems to be working . Changed crank sensor, Water temp sensor, cam position sensor, and mass airflow. All of course at different fail to start times. It has spark. When it fails to start we give it a shot of starting fluid and it starts then quits. Give it another shot of starting fluid and will stay running.We are now changing out the 219 relay and the fuel pump relay. I feel the fuel pump is intermittent??????? But my Mechanic thinks not. He says when they fail they are toast. Usually the case I agree but????There are no Codes left after changing all the sensors.What do you think?
@@patrickhellwig7658 if it starts cold let it run or go for a drive and watch the temp gauge. If it doesn’t rise it’s pouched . If it dies it’s obvious it’s something else
great video, have watched a lot of your videos already with the problems i've had with my audi a4 b8 which you videos have already helped, not sure if your still replying to comments but worth a shot. I have intermittent start issue - if left for days then go to start it takes a few seconds to start (around 10 seconds). But if i leave it only for a few hours it starts first time, no performance issues or driving issues just that first start when left for a long time. My colleague at work scanned the car for codes, nothing came up. He thinks its the valve that you mention briefly in this video, he thinks fuel is bleeding back to the tank so it takes longer to start when left for longer. Where do i look? i thought it was the fuel pump/filter but because of no other issues makes me think hes right,
Hi... yes, it could be that fuel is bleeding back into the fuel tank. Have you tried to cycle the key a few times (before trying to start the engine) to prime the fuel pump / system? Cycle the key ON/OFF maybe 5 times (wait 10 seconds between each cycle, you should hear the fuel pump run for 1 to 2 seconds each time) and then try to start the engine. If the engine starts quicker, then "loss of prime" was the issue. Thank you for watching!
@@EXOVCDS damn that was quick reply, still watching your other videos haha, yes already done this i think it primes when opening the door as you can hear it? but yes done this test and it does then start. What part/parts should i be looking at?
@@sambachellier2583 I believe the pump itself would contain the "check valve"... I don't think it's a part that you can buy separately . REplacing the pump would be the only way to go. Unless you could figure out where to splice / attach an additional check valve.
great video! I replaced the door lock on my b7 A4 while watching your video. question for you - I need to have some electrical troubleshooting done (DRL out on one side no bulb, tail light working but error and electric motor for roof not engaging). would you know someone who specializes in Audi / electrical troubleshooting in the lower mainland? thanks again for your videos !
Not sure of a place. I would look at a wiring diagram to see what controls what / what feeds power to what... just to see if something sticks out. Check for rodent droppings / smell under the hood... this can point to wiring issues (they like to chew on wires).
Have you ever come across an b6 a4 1.8T quattro with a return full line? I saw how you capped that part of the new fuel pump and you said only the fwd models use that line. I have a A4 2002 quattro and for some reason mine has a return line, which is screwing me up because now I don't know now if I should cap it or plug the line in. If you can shed some light on that please, I would appreciate it. Thanks.
Don't cap anything off... use all lines that are on your car. I haven't watched this video since posting it. Title says 3.0L... if yours is a 1.8t, that would explain why things are different. If the sending unit does not have enough fittings to accomodate all the lines that are on your car... then the sending unit is not the correct one for your car.
Hi 1Wild...how are you doing!!?? Hope all is well... you haven't uploaded in quite some time. Work still keeping you busy or have you retired? Merry Christmas & Happy New year to you & yours!
@@EXOVCDS You know how it is life gets in the way sometimes! LOL!! All good just been busy helping a friend out. Merry Christmas to you and yours also and a happy new year!! Brother. Oh I was wondering if you can give me a hand on a buddies 2003 Audi A4 3.0 Quattro he had a prolonged cranking issue with his car after sitting awhile. He changed the fuel pump , filter, and even the fuel pressure reg. and fuel pump relay. any thoughts?? I’m going to look at it for him today or tomorrow so help would be greatly appreciated
Can't think of anything / any known issues off the top of my head. Let me know if you need service info... I'll send you some pdf's if you do. Only does it first crank / start of the day? Fine for the rest of the day? Usual starting issue suspects are EVAP Purge valve, crankshaft position sensor, fuel contamination, cam / crank timing (but that usually should set a code). Any other past / recent service that was done... that could have led up to this?
@@EXOVCDS Thanks for getting back to me. Yes usually if it’s the first start of the day and if it sits a little. As far as parts Wow!! They threw the kitchen sink at it! LOL!!! Mass air flow sensor, fuel pump, one coil ( miss fire cyl. 6) and a crank sensor, fuel filter, and a fuel pump relay. Still say thing. Crazy right
I have a 2010 audi a4 2.0 quarto car, I have to do this, but I guess my question is I want to do my fuel filter also ,I Google it it says it is also in the gas tank, are they 2 separate parts ,in 2 separate places or both under the back seat,please and thank you
Thomas EXOVCDS ,thank you for your help OMG sorry I asked, well I know from your video I can do the fuel pump, but the filter I'm not so sure. Thanks again
I’m having a problem with my b7 s4 it cranks but it doesn’t start it’s a manual transmission and it only starts if I roll the car and pop the clutch.. after that if I turn off the car it gives me a good 3 starts with the key before I have to roll start again.. any idea what this could be??? It’s driving me crazy
Yes. Relay #1 in relay panel under driver dash. Fuse 28 is fed power by the relay for the pump. Fuse holder in left side of dash. A service manual is worth the investment.
I have an 04 and they removed the return line in the engine bay and I was having fuel pump/delivery problems. I did the timing belt recently and shortly after I was getting 172/174 errors running too rich. I was concerned that maybe my timing was off and causing it to run rich. So, I decided to look into my fuel pressure first and it was running at 100PSI constantly, lol. Turned out the internal regulator in the filter was blown. I used Mahle filter when I replaced the OEM less than 2 years ago and it didn't last long at all. I have since replaced it with a Kayser and all is well and the codes went away. Do you have any experience with the suction jet pump in the passenger side of the fuel tank? My car has stalled on me when it gets < 1/4 tank of gas. I took everything out and cleaned out the lines and didn't see any blockages, however, I am scared to let my car get that low on gas for fear of being stranded or the car dying in an intersection. Do you know if there is a way to test it somehow?
I have no experience with the suction jet pump on the fuel tank... not sure if the service manual has any information on the subject. I'll check after work tonight.
I have no power to fuel pump what so ever. Fuse has no power but the relay clicks 1 time when I turn the key but no power tho.. what r your thoughts? Anything helps
So the relay has 12v going to it but nothing to the fuse either side. Pulled the fuse and probed it no power. Think its could be a ECU thing.. sent 12v to green n yellow pump turns on fuel comes out.. and getting fuel goin to the rail, still dont want to start.
Could be crankshaft position sensor... maybe. With the relay removed, bridge the big slots (30 & 87). Fuel pump should run. Try to start the engine.. what happens? When you turn the key to ON, does the check engine light come on (it should)?
I have an Audi A6 3.0 my car was running good an then just cut off I tourned the key crank but no start I check for fuel cutting the feed line open there's fuel when when I open the switch but when I crank it there's no fuel an when I stop cranking there's fuel again ,,,, I checked the power at the pump when I open the switch there's power for a couple of seconds then goes off when I crank it no power when I stop cranking there's power for a 2 3 seconds
Thomas EXOVCDS the car had a code for the cam sensor an a multiple misfire I checked the cam an it wasent plug in an the spark plugs where old so I replaced the plugs an connected the cam sensor cleared the codes drove it for abou 45 min on the street on the freeway no prblms parked the car came outside started the car took off no prblm take off the light drive for about 2 min the car cut off try to start it nothing then I tryed again an it started came home tourned it off tryed to started it back up no start check the ecm for eney codes an nothing no codes I try to start it an nothing
Jose Martinez Can your scan tool see live engine data? Crank the engine for 10 seconds and check if the scan tool shows rpm. No rpm reading suggests crankshaft position sensor issue. How old is the timing belt?
Thomas EXOVCDS yes it can read I'll do that first thing in the morning the timing belt is like 3 months old am wondering if there coudth be a prblm with the cam sensor bein that it was unplug an that's haw they where driving the vehicle when I checked the codes it sead cam sensor so I did a visual inspection an it was unplug an the wires where really bad I plugged it bck in an drove it I dirent give me eney prblms or a code for cam after I plugged it bck in but then drove off an left me stranded but after trying for a couple of times it came on drove it home an it dirent come bck on
Jose Martinez Cam sensors usually don't prevent an engine from starting... it could be that it is creating a signal that is too erratic. Unplug it and see what happens.
at 9:29 you can see the wires attached to the fuel pump. If you hold your pump in the same position, the black wire goes to the top connection and the yellow to the bottom connection / next to the hose. Is that what you were after?
Im not sure what you are wanting to do... splice an aem? If you are talking about the 2 fuel pump wires... like I said, pump will run backwards if the wires are on wrong.

Dd you ever figure this out < I have the exact same model and it does the same thing except with a hot engine(start)
@@patrickhellwig7658 We had the hot engine no start.
We replaced the coolant temperature sensor. Fixed it.
@@curtishagley586 Ive already replaced mine once but it was from autozone or Advanced so maybe its a shitty sensor

Nice work. Bentley has not yet arrived so this was fun to watch, not least because it was a relief to learn that the pump is so accessible. Thank you.
