[@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!

[@stephaniebarbuto8000]

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.

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

I have a 2000 Volvo s70 with 190,000 miles on it. I bought it from my neighbor who had it sitting in her yard for 4 years. I changed the oil, put coolant in, cleaned the spark plugs, and lubricated the cylinders. I also tried to remove the old gas but nothing was coming out so I put 3 fresh gallons in. I also put a brand new battery in it. Then I went to crank it and it starts for maybe a second and immediately dies. I’m not sure what the next step is. I checked next to the fuel injectors to see if they were getting fuel and it seemed like they were. I’m 19 and I was motivated by your videos to buy this car.

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 !

If it runs good with the jump wire, it's likely the relay. If you pull the vacuum hose off of the pressure regulator and there is fuel in there, it's bad.

Hi Robert....I bought my 98 Volvo s70 three years ago and have been a fan of yours ever since. This car has been one problem after another. We have been stumped lately and haven't had much luck finding the right info on getting my car to start. I am hoping maybe you can help. One day out of nowhere the key stopped working and the ignition tumbler locked up and wouldn't turn. For a quick fix my husband removed the dash and we were starting the car with a screwdriver in the ignition switch...that worked for several weeks until it didn't. One day it just stopped turning over at all. The head lights come on, the radio and dash lights everything works but it doesn't even try to turn over. We have since tried replacing the tumbler, replaced the switch, replaced the starter, the battery, the neutral position sensor. He's checked all of the ground wires, fuses ect. Nothing has changed. Do you have any idea what the problem could be? Thanks in advance, Sincerely from a desperate wife looking to help her husband Jessica

Hi Robert, thanks for all your videos. I have a 1998 S90, it has a lot of pressure in thank, I also has a strong smell of gas inside the car. any ideas what will cause this problem? Thank you

[@RobertDIY]

Probably a vacuum leak under the hood.

Thanks Robert for the very useful video.My 1998 petrol volvo v 40 would not start.I suspect the fuel pump.The relay is good.I ve ordered a new pump.Just wondering if you can replace the pump yourself.Is it a big job.Where is it located and how to reach it.Thanks.

[@RobertDIY]

I don't know. Try a Google search.

Hey Robert, I have a puzzle for ya... It's a 98 s70 t5 that randomly wont crank or start, I'm getting some fuel(after trying to start it quite a few times, I push the Schrader valve on the fuel rail and I get about a teaspoon maybe a tablespoon of fuel). When I'm sitting in the car trying to start it I cannot hear the pump at all, even with the back seat laid down and the trunk carpet pulled back so the fuel pump access cover is visible/accessible. Perhaps I should also add that the economy and sport mode buttons' lights are both lit up (along with all other interior lights; dome dash window controls etc.) and with any combination of pushing the three buttons they won't go out. The upshift arrow on the instrument cluster is the only one not lit up, and if I remember correctly it used to light up with the rest of them when u turn the key to the on position. The SRS light is the first to come on (key in and turned to position 1) and the first to go off(as soon as I turn key to start position-position 3). I know the battery is good, its been tested and on a charger.(Not continuously of course) The main thing that changed between the last time it ran(I've considered lawnmower syndrome since I only turned it around in the driveway and shut it right back off...thoughts on that..?) and now is that it wouldn't crank or start(obviously) and in return, I assumed fuel pump relay, and attempted to jump it however I read the relay wrong and jumped the incorrect terminals in the car, causing just a slight amount of smoke to come out from under the incorrectly jumped terminals before I quickly took the jump wire off. No fuses or wires are visibly burnt, from the top that is, I tested fuses with a light and fuel and starter relays have both been swapped out. Problem remains...**HUGE sigh*** Assuming the worst and sadly trusting my childlike instinct of guilt, that I broke it.... :( that in my relay jumping attempt I melted a wire under the fuse panel... Which seems practically impossible, in theory, to repair, or at least difficult and frustrating enough to make one tear their hair out.... Therefore, with learning (the hard way of course) that u can't pull the panel out from the top (where u would check/change the fuse) since there are other wires/harnesses connected from below, that can only be accessed by removing the drivers kick panel, this is my next approach.. Oh one last small detail, I have another volvo (97 850 GLT) and the keys look almost identical....my dad (who's very mechanically knowledgeable yet doesn't know much at all about volvos in particular) tried starting my s70 to move it one night, except he used the 850 key...did he ruin the sync between the chip in the key and the ECU?? Please say no hahaha, I do not want to go to volvo and blow a bunch of money.... Knowing ALL of that, do u have any thoughts, suggestions, (advice not to touch certain things.....:/) I'll take any input u or anyone else has, and I do greatly appreciate everyone's help in advance, as well as the time u may take to read all my jibber jabber.. :) Thank You!!!!! :) :) :) :) :)

Ok

[@betsystevenson921]

Thank you Robert! I will mention this to my Mechanic! It’s been a real problem for him to diagnose! No code coming up & he has had it for a week drove it & it didn’t stall once😣 it’s odd because it happened to me on the way to the shop! I’m going to call him & determine if I’m gonna let him try again or pick it up and try a different mechanic! Any advise for a girl?? As I mentioned he’s had it since Monday! European Car Authority! 🤔 1998 Volvo S70

Did you watch the video? You can do this stuff yourself.

[@potterg04]

Thanks Robert, that was very helpful information I appreciate it.

[@RobertDIY]

You are welcome.

[@DeathBotzz]

Think the relay could cause the car to not get enough fuel after about 1 minute of running perfectly once started?

[@RobertDIY]

Sure

[@90Ming90]

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.

[@RobertDIY]

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

[@martinkieth9882]

+Robert DIY so I have to buy the PVC kit ? and its not starting so I figure a bad PVC won't let the car start

[@ranjohn02]

Martin Kieth I was wondering if you figure out what was wrong with your car. I have a 1997 960 that act up the same way as yours.

[@rashellyohn5128]

Thank you so much for your shared car knowledge. would you know if I could swap out a 5 pin relay for the 4 pin fuel pump relay? I noticed that there are placements for more then 4 pins in the circuit board that the fuel pump relay connects to. How long could I drive with a jumper wire. I need to go about 40- 55 miles. I am waiting to find a fuel pump relay for a 89 S70. Thank you for allowing me to gain some of your expertise.

[@RobertDIY]

I drove with a jump wire for about 10,000 miles.

You ever replace the pcv with a oil catch can on these volvos?

[@RobertDIY]

You don't replace the oil trap box you add a catch can.

[@ls6z061]

so my s70 pump primes but the pump never runs again and car will not start. it did start sometimes after stalling but now it wont start at all. I did the jumper and the pump runs and so does the car. so just a bad relay. could it be that simple? it primes to the correct fuel pressure but goes to zero when trying to start.

[@RobertDIY]

Yep. Did you drive it with the jump wire installed?

[@ls6z061]

Car ran great. I ordered a new controller that just arrived. looks like problem is solved.

[@thomaswilkinson6276]

Hi Robert. Can you tell me what those three relays in the fusebox area marked with the letter "J" control?

[@RobertDIY]

One controls the cabin fan, one controls something with the starting circuit. You can get a wiring diagram or pull them and see what happens.

Well I wish I knew about this before I went and got a new fuel pump all mine needed was a relay. I didn't know the cruise control had one either

[@RobertDIY]

+Joshua Barrera now you know. Any other problems, come here first.

[@kramsavoilesik7009]

Hi Robert. Your video has already been a great help to me. I have a question hopefully you can answer: Do I need a fuel pump relay made specifically for an automatic transmission? My auto parts dealer has one in stock and they told me it is for a manual transmission only. Is this true or is the fuel pump relay for my 1997 Volvo 850 universal for both transmissions? Thank you in advance.

[@RobertDIY]

I would think either would work. You can install a jump wire and order the right part.
