[@BillyDiamond]

The only place I turn to on the internet for help in fixing my Volvo myself is here and to Robert. ONCE AGAIN.... ROBERT SAVED THE DAY! I was experiencing the frustration of random stalling. I knew it could be a variety of things, but didn't know where to check first. After watching this video I quickly made myself a squab (jump) wire, pulled my relay, and let the car run. It did not shut off so I went to work ordering one right away. Advance Auto wanted about $66 for my 1998 V70 AWD, while AutoZone was around $47. I had it same day, easily replaced it (as easy as replacing a light bulb at home) and the next day confidently drove it out of state with about a 400 mile round trip. It did NOT STALL and has not stalled since. Robert, you are worth your weight in gold and just an all-around nice guy (whom I have even had the pleasure of chatting with on the phone). Please remind us that you accept PayPal Tips and where to go to do that. I hope that I am not the only one tipping this man for all his content, education and hard work. Volvo for Life baby, Volvo for Life!

Robert you are the man!!!!! Thanks to you, I finally figured out my weird starting problem with my 1997 Volvo 850 wagon!!!! It was the fuel pump relay! Its been so frustrating because it would start fine but then if I drove it for a bit, stopped and tried to start it again, it would't start. If I then waited about a half hour, it would start again. But this would only happen when it rained out. I got stranded so many times waiting for it to start again. I replaced the fuel pump relay and drove around all day in the rain today with no issues restarting it. I've been trying to figure this out for a long time. I'm a 51 year old woman with not a lot of money to go to a mechanic so THANK YOU SO MUCH, ROBERT!!!!

[@whitesapphire5865]

Just about to try this in my '99 S70. It died on me yesterday afternoon. The engine quit on me in town, but I was able to restart it straight away. I had presence of mind to come home at that point (about a 20 minute drive) and the car drove normally. After stopping the engine while I took a few things out of the car, tried to start it up again, and this time, nothing doing. I studied the repair manual, which tells you almost nothing, but wiring diagram shows the circuit very clearly. I was just a bit dubious about hitting the pump with a constant 12v supply, but from your video it looks like the pump won't suffer in the short term, so that's what I plan to do.

[@stephenmoore1998]

Robert: thanks for this series of videos, I have learned a lot that I wish I know when I owed an S90. Never needed to work on my 245. In any case, now I've got an 1988 S70 GLT that has been nothing but a headache. Drove well for a year after buying with 180K, but for the last 6 months its been noting but CEL, trips to the mechanic, and then new problems arise. Latest issue is random stalling when the weather gets hotter (over 80 degrees). In recent weeks I've replaced the plugs, rotor, distributor cap, plug wires, coil and just yesterday, the infamous fuel pump relay based on your video. It was NOT a Volvo part, but a Kaehler unit. Now random stalling has increased to the point where if it's over 80 degrees, stalls almost immediately while cooler temps seem to let it drag out a bit. I wait a bit, (higher temp dictates longer wait), and car starts up but then stalls again almost immediately. No codes display, just the cryptic '0 dtc' on my $29 Autozone OBD reader. Very occasionally I get the P0455 code, which I think is the J&L hoses located in the trolls-only service area.

[@RobertDIY]

Did you try a jump wire?

[@RobertDIY]

Also check the battery B cables, clean them.

[@RobertDIY]

kzbin.info/www/bejne/hIjJfaOmbbOYrKs

[@stephenmoore1998]

Yes to jump wire (started, ran 5 min, stalled), yes to battery cables, watched the failing fuel pump video. You are a funny guy! Yeah, I've got the 225K miles, but car ran like a rocket ship after the recent tuneup, and always started (before it started to stall). Time for a trip to the junkyard, but if I can't find an OEM pump and fuel relay, will got to Amazon. However, I took a look at your other video about the things to look for when buying a S70. Timing belt has over 100K. AC is toast. Think I'm going to push to the back of the yard with the other projects, and take a flyer on a newer car. Once I get the current project out of the garage, this would probably be the next one. Thanks again for all the useful videos, Robert. All the Volvo mechanics in Maine I knew retired once they started bringing out the newer cars, or stuck to 240's

Good Work!! I've had two Volvos that stalled going down the road...FINALLY traced it to the relay...

Hi Robert! You are a huge blessing sir! I recently bought a 97 850 and a few days after the car shut off. Got it fired back up but sputtered and lost power, then died. Beat on trunk floor and fired back up. No real issues for about a month other than occasional sputter. Yesterday I left car on while I went into the store, came back out and car wasn't running. Let it sit about 4 hours and came back. Beat on floor...nothing. Then beat on floor while a friend turned over. It fired up! Barely made it to my driveway and she died in my driveway. Wouldn't fire again. I'm hoping it's the relay! I will let you know if this fixed me up. BTW....check engine light stays on but no codes at AutoZone. Service light is intermittent

Hey Robert, i have the issues listed above in my 1996, 850. It wouldn't start, when it would start I could drive about 100ft before it would stall out, then it wouldnt turn over. I started by replacing the relay (common issue) and the car started ! Held idle and it seemed like I fixed the issue by replacing the relay. The next morning I drove it to work and after about 30 mins on the road it died on me, same issue, Back to square one.. I went and got myself a new fuel pump.. Not OEM because I couldn't find one in town. I replaced the pump, unplugged the relay (newer) and put it back in. Tested the pump and it was humming ! Seemed to have fixed the issue... Started and it held idle ! Let it idle for about 10 mins before I decided to drive it a bit to charge the battery. As soon as I hit the gas I could feel the car bogging out and sure enough it stalled out again... I'm at a loss. The car was working fine. I was told running on less than a quarter tank too often is bad for the pump ? I'm also wondering if my new relay went bad when my car stalled out on my way to work ? I'm also wondering if the new fuel pump I put it there is a dud because it's not a Bosch. Please get back to me ! Thanks for putting out great content !

Ive tried to take out the fuel pump relay when this happens and put it back in. I also tried to jump the relay with a wire and clamps as you illustrated, but no start.

I have a 1996 850 R, the car has become harder to start than normal, I cannot hear the normal pressuring up of the system when the key is position 2. When it drives it hesitates like its going to stall when you touch the peddle , its auto by the way, and it will drive away slowly and gets to 30/40 mph but doesn't want to "go" especially uphills and gear shifts are a bit random, it has the feeling of not enough fuel but can the relay only half work. It had a new fuel pump about 2 years ago. my other thought if it wasnt the relay w was fuel filter. any thoughts

[@RobertDIY]

Glad you figured it out.

[@tshepomadumo1856]

hi Robert i have 2005 s40 no petrol coming out of the petrol rail any suggestion?

Hey, Robert! Could you please make a tutorial on how to lift up the fuse box? I'm interested in seeing how you can replace the B+ battery cable in a 96 850. I do not have a secondary box near the abs, just the one with the relays. Thanks!

[@RobertDIY]

I have tried a few times. I'll try again in a few days.

Most people just splice into the wire harness about 12 inches back.

Hello Robert, I would like to know, if you will please, would the Volvo S70 fuel pump make a noise like a pump sound for only about 2 seconds after you start it, if the relay was bad but had a good pump? On the S70, is the pump under the rear seat or in the trunk under the panel? Thank you so much for your help.

Huh?

Did you watch the video?

[@daveschannel49]

Hey Robert thanks for this video. But my car hesitates to struggle only when it's hot outside can that be the relay problem? Thanks

[@RobertDIY]

+Dave Cruz huh? Hesitates to struggle?

[@daveschannel49]

Robert DIY yea I mean it won't start right away. It's hard to start it cranks but takes a few try's. And u can hear the fuel pump clearly tho.

[@RobertDIY]

+Dave Cruz did you try jumping the relay socket?

[@chrisnicolaou8095]

I HAVE A XC70 3.2L 2010, IS THE RELAY LOCATION THE SAME AS YOUR VIDEO ? THANK YOU

[@RobertDIY]

Does not have one.

[@Ehroncovers]

If I replaced the relay but had a bad pump, would I have to get another relay when I replace the old pump ? And does having a full tank help remedy this issue ? Thanks !

No, no.

[@ronnieparsons362]

Is there any thing else that would cause random stalling? Could a bad pcv system cause stalling? Plus why may the relay continue to go bad multiple times?

Hello Robert thanks for the videos. I tried to jump the relay but didnt hear anything at all from the fuel pump, and its quiet out hear. But, I did get gas coming out of valve that you spoke of. So would my pump still be good if I am getting gas. I have a 98 volvo S70.

[@RobertDIY]

I don't know, how much gas came out?

[@RobertDIY]

What's the problem with the car?

[@rashellyohn5128]

well, the car had been sitting so I figure it wasnt just left over gas. It had a little presure to it because it didnt just fall directly down, it shot out. It was about a 3 table spoon.

[@prestonbyrd2670]

I have a s70 it's sputtering and stalling. If fuel is comming out the filter when I disconnected it can it still be bad? Thanks Robert

Probably a vacuum leak under the hood.

I just bought a 1998 V70 GLT.. and it starts runs for about 3 seconds and dies. The fuel pump seems to be turning on.. but if the relay is bad wouldn’t that cause the pump not to work? I’m gonna replace the relay and see what happens anyways..

Hi Robert. My 2001 Volvo V70 XC wouldn't start after going into the sore for 10 minutes. I did 2 of the diagnostic checks you described in the video: checked fuel rail pressure via pushing fuel release valve and listening for fuel pump activation. There was very little/low pressure on the fuel rail and I couldn't hear a sound when listening for the fuel pump. Therefore, i think I am gonna loosen the fuel line going to the fuel filter and check to see if there is any fuel being pushed through. Secondly, if there is no fuel movement I will proceed to check the fuel relay and use your jump wire method. Lastly, once jumping if there isn't any action I will make a strong inference that the actual gas pump must be bad. Could you let me know if that is a feasible order of approach I am taking?

[@RobertDIY]

Has the check engine light been on? I don't think your model has the fuel pump relay like the 2000 and older cars.

[@arnelebrato8832]

It's on the CEM under the dash by the driver's feet, on the left side.

[@NakimaScorpioLove]

Hi again, so we got it to start ( volvo xc70 2004) ended up replacing the engine and block with one from a 2004 s60 non turbo..added the turbo to the engine. Well, it's starting, yet when idle it seems to drag, feel like the car will cut off and it did twice. I'm wondering if that is a timing issue or if the specs are off because of the engine swap. Was wondering if you know?

[@RobertDIY]

You'll need to scan it for codes and make sure all of the connections are proper.

[@LubaLuba1]

Can I use jumper wire for my S60 as well because I think relay is inside under steering close to door

[@RobertDIY]

I don't think it has one.

[@RobertDIY]

Any codes?

[@dwightgeorgecarlson]

I gather the computer sends power to the relay to activate it. Does the fuel pump run continuously or does it turn on and off as commanded by the computer. If on and off, what does the computer use as a signal that it should power the relay and thus the pump?

[@RobertDIY]

+DG Carlson are you going somewhere with all of this? I don't even know what kind of car you have.

Robert, Hope you can help out. My 2007 Volvo xc90 .was showing overvoltage on the dashboard ,got the alternator and battery changed. Now the battery light came back with the red triangle on the dashboard. Scanned the engine and got the P0190 code. Interpreted as fuel rail pressure sensor circuit malfunction. Is this expensive to fix ?

I own a 96 850 non turbo, I was having this trouble so I replaced the fuel pump relay, the spark plugs and distributor cap, the ignition coil and lastly the battery. Mechanic said the fuel pump was working but left it at that, any idea of what else it could be? Engine cranks but will not start.

Robert I have a 1996 850 glt wagon. If it is cold, it will start and run great for around 5 minutes. Then it dies and when you try to restart it it acts like it is not getting enough gas. I have replaced the fuel filter, fuel pump and jumped the fuel pump relay with no change. I have checked the compression, checked the timing, installed new plugs, cleaned the rotor, installed new air filter, and new crank position sensor. The only error code is P0410 - the air pump. I guess I'll buy another fuel pump relay. I am stumped, since jumping the relay did not correct the problem. Any other suggestions? Thanks Rahbin
