The Video Robert DIY Should Have Made!
/ rspi007
Between your video and Robert's I was able to fix my 940. The hot engine hard start condition was indeed the fuel pressure regulator just as Robert's. Thanks for the help both of you guys are awesome.
😂 This is true, my 740 did have a bad fuel pressure regulator but it didn't spill out like this one.
Funny thing about this video is I used to nickname several people Nimrod. 😅
Thanks so much for this man, I have a 91 240, and I’ve been throwing parts at it for 4 months now and this 100% fixed it!
Glad it helped! we have a 91 240 now as well, and will be doing some more Volvo fixing video's soon! stay tuned!!
LOL
bruhh literally same, this fixed it and i couldn’t be happier
You were able to run it for 4 months without issues? I still have hope then, as I'm going to be racing tomorrow.
@@JamesBond00797 it idled rough. amd hhad to hold peedal to the floor when starting it
Glad this was the first thing I saw in my search for idle/start issues! A quick check of the regulator revealed that mine was spitting fuel too.
glad you found your fix !
Perfect. Thanks from SWEDEN.
Glad it helped!
Volvo 940 the best car in the world, for all times! From Russia with love!
Greetings from coastal North Carolina. Love my 91 240. I heard that a Chinese company bought out Volvo. True?
I have a transparent rubber line on the fuel pressure regulator and indeed sometimes I can see some liquid running through it so I'm definitely going to replace it. Thanks!
Thank you so much for posting this. I have a 95 940 with 440k miles. It was about time to change this guy out. Everytime during long drives I would turn my car on and it would idle so rough.
I'm glad it helped , and thanks for subscribing! 🤠
Perfekt Tip! Had exactly same fault on my fuel pressure regulator! Thanks man!
Great to hear!
Love my Volvo. Love the video. I’m having this problem, after paying hundreds to get it fixed for smog repair…oy. I’m going to check it tomorrow when it’s light! Thank you, Nimrod!
forgot to tight up the back hose to the regulator.. it happens ! thanks for sharing sir.
you got it , good to see your paying attention!!
Thanks for the video. This is the exact problem I start to have with my 1990 240. I will check the regulator first.
Good luck!
@@yankeenimrod2063 Pull the vacuum line, sure enough the regulator front is leaking fuel, in fact the hose is full of fuel. Order a genuine Volvo regulator from IPD and installed a few days ago, and the engine runs very smoothly now. Starts no problem and the fuel efficiency has improved. Great Vid. Thank you!!!
btw, it rids of the gas smell at outside when engine starts.
@@dr.magnanimous8973 I'm glad it worked! keep that 240 rolling!
Excellent! Thanks for the video!
Thanks for the video. Excellent info - I'll check my 240 tomorrow.
your welcome! thanks for watching !
I have no fuel coming out of the regulator but when I plug the vacuum hose the car idles much better, think it might still be the problem?
Same. Found the issue?
You forgot to tighten the band at the fuel hose.. 😉😬
thanks for subscribing
Sometimes the diaphragms have pin-hole leaks. Smell the hose on the front. If it smells like gas the FPR is indeed bad.
good point Chris, 👍
I’m having weird cold start issues with initial rough idle but then sorts itself out when the engine warms up. I just removed the hose on the front and it smells like gas. I’ll pull it and see if it leaks tmrw, just in case. but I should probably be placing an order for a new fuel pressure regulator? I thought maybe it could also be the coolant temp sensor what do you guys think?
Great vid thanks for posting, Would this cause jerking and stalling?
posable
nice fix 👍, and ya didnt lose the 10mm 👍😃
hose clamp on the rail side of reg.
I haven't made T-shirts yet but when I do you get the first one!
@@yankeenimrod2063 LoL Yes 👍
Helpful thanks
Glad it helped
Wow, sasquach volvo..😂
I will try tomorow
any luck ?
@@yankeenimrod2063 yeess i did it, i buy new fuel press regulator and the engine running very well, thanks
THANK YOU!!!
You're welcome!
You missed tighting the hose on the back part of the regulator. I'll expect my gorilla gloves in the mail please
Vacuum line to my regulator broke while I was replacing the injectors.... After figuring they'd gone bad.
"Oh, petrol smell. And leak out the vacuum pipe."
New regulatir on order... *sigh*
I just watched this again. It looks like you didn't tighten the rubber hose?
you got it!
The hose on the back part of the regulator wasn't seated flush with the regulator and you needed to tighten it.
correct I did not tighten the hose clamp on the back hose! good to see some one pay's attention!
@@yankeenimrod2063 I have a 1993 Volvo 240 wagon. Going to have to do a compression test on my red block or do a leak down test.
Hopefully its just something simple ! haven't gone that route yet with a car engine. let me know what it ends up being. I have a 93 240 as well!
Nobody made a video on how to separate the headlight from the bracket so i made 1
I have a 1988 760 Turbo the car went off the battery is completely discharged before it shut itself noff there was white smoke is that the samebproblem?.
no, you may have more then one problem
On our 940 B230FK, when it starts it idles smoothly. However after it warms up, the idle goes off. When you stop at traffic lights, the engine will dip by 100rpm every third or fourth beat, causing a shake. Any idea what's up there?
I have this same issue!! Any luck with it? I’m gonna try the fuel pressure regulator this weekend.
@@WesternWagon-i5z Sadly not. The symptoms changed on ours so that its idle is now terrible from start for about 5 to 10 minutes then improves. I will need to do some actual testing, e.g. compression test, pressure test, fuel pressure test. The FPR on ours doesn't appear to leak so I didn't change it - are they available? I changed the O2 sensor, ignition module and relay, fuel pump relay, HT Leads and spark plugs as I had them here but no change. I will probably take apart the distributor, do a smoke test on the vac lines as I just can't see any breaks, and renew the intake and exhaust gaskets. The car runs 'good enough' so never major emergency but it's a shame to see it not at its best. Hopefully you get yours sorted!
You forgot to tighten the torx clamp
Missed thay back hose
I want gorilla driving gloves! My birthday is in a month!
Merhabalar 1993 2.0gl 940 Volvo sahibiyim aracım arıza verdi usta ile çözemiyoruz
Araca yakıt geliyor çalışmıyor Eco sağlam kontrol edildi ateşleme mevcut sürekli basınca araç komple ateşleme ve enjektörlere verilen elektriği kesiyor krank sensörü bujiler buji kabloları degisti sizce sorun neden olabilir
Thanks brother, how much did the part cost mate?
$36.79 US dollars. welcome to the Nimrod Nation 👍🤠
hi mate , iv got a 1989 740 GLE (B230E "K-jet") and it has a misfire symptom when giving throttle (checked the sparks and intake leak check and leads are fine same for dizzy) but sometime youll start it and it will be fine BUT every time i try to start it i have to give throttle , any clues ??? i dont have a fuel regulator on the engine
No fuel regulator on your 740? How come? My ‘88 had one
@@TerminatedEfficiency was it a Kjet system , the K JET fuel system doesnt have a regulator
Is it possible for this to be the issue if it only has a rough idle and hard to start when hot?
probably, it' only takes a minute to check it.
Did you find the solution for this?
@@roguesociety5803 yeah was a temperature sensor can't remember which
thanks dude
Will this cure my 850s rough idle ?
no, the 850,has a different system, I can't help you there sorry
Has to be check while engine is running.
NO if it is really leaking you will smell fuel or see it when you pull the vacuum line. but it helps if it's running
You didn’t tighten the hose clamp
you got it thanks for watching !
You did not disconnect the battery!
true I did not disconnect the battery, but that's not what were looking for!
Need to get your hand model Buick back , or where gloves when you’re flapping-your old hands around in the video!
I believe Buick is still in quarantine

Biden won, I am from liberal socialist CA and am not a fool. Good video, thank you
I'm glad you liked the video and watched it to completion. We are probably not going to agree on politics, but that's ok!
I have no fuel coming out of the regulator but when I plug the vacuum hose the car idles much better, think it might still be the problem?
