Love how you don't hide any flaws. Most car guys hide the small imperfections. Keep up good work
Send the injectors to FIC. They’ll Ultrasonic clean it, flow test, dyno flow chart and they’ll replace the filters and seals. It doesnt have to be fic brand.
This could be a bad fuel regulator tbh. but injectors usually needs servicing anyways its a maintenance. Ill say do it as precaution. My injectors were getting stuck over 6krpm and I sent it to fic. Its $25 each for all the testing cleaning and restoration.
Both the fpr and Injectors are fairly new.. thanks for the advice!
If you changed the fuel pump you should’ve changed the strainer while at it. That strainer in there looked way overdue for a change.
Didn’t realize it didn’t come with a sock. I don’t think that’s enough to make it run like that though
@@MiguelDsm Yeah usually they’re sold separately. Could be one of the reasons why you keep frying them though. If that strainer is deteriorating or is dirty from particles from the gas tank it could get sucked up in it the lines and pump.
Bullseye!
Oh shit, you just happened to go through exactly what happened to me, you see, that sock filter was fully clogged, I had that in my red Eclipse and managed to kill a walbro when it started whining like that, because she was building too much backpressure and started overheating until she had the bearings messed up, and just last week my brother started to had the same in his SRT-4 also with a walbro, since then I have several of those sock filters just in case, they are cheap and better replace them everytime you have the pump out and they are looking greyish.
I happened to suspect that since some of your VR4 videos a long time ago, but didn't comment on it because I wasn't sure my self, but now I'm 100% sure, also check your other fuel filter too, just in case.
Thanks for the input! I’ll go ahead and get the sock ordered
these cars are supposed to run at 43psi of fuel pressure. I would absolutely check the fuel pressure regulator as well for your bleed off issue. might as well bump it to 43psi just to see if it changes anything. i bet your gsx also runs at 43psi. 36psi just isnt enough. Hope you get it working soon, my brother has a 92 vr4 3k and its cool to see your vids about them! I have a 1992 galant vr4 that I am getting back on the road soon, will start posting vids once i get it running.
Keep it up dude. Don't give up. We are all rooting for you
Mine had similar issues, turned out to be the MAF. It would lean the car out crazy and caused it to sputter and freak out similar to yours. I'd also check the TPS, you should be able to see if its reading correctly with a laptop (as you have a flashable ECU) it will give you a reading and show your % as you move the peddle. You want to make sure that the ECU is reading that you are giving it throttle, and adjusting the fuel trim appropriately. My guess is its the MAF though. Try unplugging it and see if that changes anything. Start simple and go from there. If the MAF and TPS are good, but its still running lean, with a new pump and all that, I'd check the fuel filter (just to make sure it's not faulty and somehow clogged) and redo the flash. Recheck the values the flash is tuned for, want to make sure it has the correct fuel trims you are looking for. Good luck and keep us posted! Not enough 3000gt content out there now days.
I appreciate your input!
We’ll get it figured out. Need to make sure fuel pressure is consistent. Go pro filming the pressure gauge can be used to monitor that and then also check voltage to the pump
Appreciate all your posts and showing others what you are going through. It helps everyone on the platform and I for one it helps keep the passion alive to continue working on our own cars. Thank you.
Good video glad to see the VR4
Could be a faulty fuel regulator or leaking fuel injector. If there is no fuel pressure after ignition is turned off, and/or you see the pressure is bleeding slowly. It might be an injector. Have you checked your oil for gas smell? Have you looked at your plugs? I know the rear are a pain to check, but at least you can start removing possible problems.
Injectors and fpr are brand new. I’ll check the smell of oil
@@MiguelDsm Well, this is a good thing. Less items to check. It seemed that once you began getting on the throttle is when the engine began to bog down. I am still thinking that the problem may be fuel related. You have changed the fuel lines to braided steel lines? I do not see lines like those crimping. Maybe a bad connection somewhere that air is being sucked in and the system is not being fully pressurized. Then again, you would smell gas. Either at the back of the car or toward the front. But it may be a small leak somewhere that you may not be smelling it. Just a thought.
Fuel tank sediment may have entered into the lines. You did say the car sat for some time.
The other item is fuel pump which you just changed. But perhaps the pump is not getting enough power and is turning/pumping slower than it should. Check the power wire coming back to the pump with a voltmeter and check if voltage is in spec.
These are all just thoughts.
Ah the pain of cars. Love the VR4 content! My FTO is still broken and every time I see your VR4 I miss some of the sound so much
Does the fto have the same platform?
@@MiguelDsm Similar, a 2L V6 (code 6A12). Being quite complex not many here in Aus know about it let alone would be willing to help out unfortunately. She’s currently running on 3 cylinders for some reason and very very rough. I suspect timing issues :(
Little update as of today: Checked the timing and the cams appeared to be all good but the crank is off by 1 tooth. Need to double check piston 1 is at TDC then if so adjust that timing and maybe. Just maybe it’ll run properly
I usually datalog when I’m having an issue like this. All the data you can see while it’s happening will help tell you what’s wrong. When my maf was bad I could see the airflow signal drop on the datalog. If your tps is bad you’ll be able to see that too. Hook up your wideband and a fuel pressure sensor to the ecu so you can datalog those parameters as well, will help diagnose any other issues in the future.
Keep pushing brother!! You got this, trust once its running at 100% that thing is scary fast 💨 and youll want to get bigger turbos lol, btw i just deleted the clutch assist on mine lmao the valve hose went back so now i got that heavy clutch pedal😬 turns out to be a good workout
I did the same thing lol
check the inside of the fuel tank itself incase it's rusted out, chemical treat and red kote it
The whine is absolutely normal for wahlbro’s. Not too familiar with that specific engine but I would definitely check your fuel pressure regulator or see if that car has a fuel pressure sensor. Also get a new strainer on the new fuel pump so it doesn’t crap out
If you haven't rebuilt the throttle body for sure you should do that. It's pretty cheap and easy. I can help if you need it I'm in HB but I'm not on insta.
Check the fuel power supply line, I had a similar problem in my AE86 and I asked for a kit for the pump power line and it was solved. What I think is that when you change the fuel pump for one with greater power, it consumes more energy and the lines get hot and the pump fails.
If you bought the fuel injectors online I'd check them out first. The problem with many of the internet buys is that they actually work...but if you test them a lot of times they are not consistent.
This sux. Totally feel your pain. We've fought problem after problem with my son's 2g. The 420a runs good for a few months, then something pops up. We keep at it though. Don't give up. You'll figure it out.
Part of the game
That wine from the fuel pump is normal .
Problems like these, It looks like the map sensor isn't functioning properly, also check the TPS and look if the check engine light is on the dashboard. I would suggest u get te car scanned too.
Love the vr4 content you’re the reason I got mine keep the posts coming 🎉
Mr car was doing something a little similar. Just not quite as severe. Lurching under throttle and weird rpm/jumping around a ton. I believe the issue was some of the injector plugs weren’t seated/connected properly. Aswell as the Throttle position sensor. I fixed them and the issue went away! Hope you’re able to fix yours up!! Sick car 🔥
Thanks for the insights! I’ll look over the Injector seals and tps
@@MiguelDsm
For the injectors, it was the plug in / sensor connectors on the top. Can’t remember the name. But they are in an orange wire casing right under the fuel rail
I think your injectors or fuel filter is plugged up with something. But considering it loses pressure right away I would look at the fuel filter, if that was plugged then the pump would have to work hard to push through it and once off the pressure might purge off into the return. Also the sock on the fuel pump looks pretty gross and might need replacing along with the tank. Love your car, it is sick and those of us with these cars, it is a passion. I bought mine destroyed by a kid, new long block, rebuilt the turbos, , rebuilt front suspension with tierods, ball joints and struts, That is hilarious that trim fell off, I just got my car running and was doing a short interstate test and that ripped off those clips and was hanging by the fluid line. Just working on keeping it on the road, next I lost my clutch and think it just needs to be bled.
Does bled the clutch and my car is driving again. Easy 15 minute job.
My favorite car/build on RUclips
Yes Walbros can be kinda loud, part of its charm. Perfectly normal..
Definitely doesn't hurt to change the strainer and fuel filter as the others have mentioned. Maybe that relay is faulty? Good luck dude.
It's probably the AFPR, I just finished my DSM and I am having a similar issue....the only thing that isn't brand new is the fpr, so I am going to change it
Even if it’s fairly new?
@@MiguelDsm Try restricting the return hose after the regulator and see if it holds pressure longer.... don't block it entirely because it needs to let some fuel return.....just enough to see if it makes a difference. That should tell you which direction the fuel is free flowing back to the tank
Dude the walbro is so annoyingly loud. I finally couldn't take it and got the denso one from the supra. Twice the cost but way quieter and flows more and more reliable.
If my socks looked like that I’d change the tank fuel pump and sock, and get a new fuel filter. Both those socks were disgusting.
Man those things are bad ass but heard they were a nightmare to work on
Definitely need to change that fuel sock. Mine didnt even look that bad and my dsm wouldnt even hold an idle when i first bought it. Changed the sock and ran great. Also check you fuel filter and make sure the 3kgt doesn't have an inline check valve rhat could have gone bad.
I wished I lived in a area like you. I'm in the pnw and I just want to be with my cars with nice weather. It's snowing here 🤬
Don’t know if you found the problem but on mine I had the same issue out of nowhere it would hesitate just like that I checked everything from fuel to injectors timing u name it long story short 2 weeks before I had changed the throttle position sensors there was nothing wrong with my old one was just old I turned it on one
Morning and it went crazy on me put the old one back and solved my issue it was a autozone part by the way
Yeah theyre so dope , but that’s i why I got a an SL because I wanted to spend more of my time driving it and touring it on trips n stuff lol 👍
I think that depends on the maintenance records for the car. A vr4 Can be just as reliable as an sl if it was taken cared for well
@@MiguelDsm finding one that has been could be hard ,seen one for around 8k but it had 230 k miles and a couple more but always issues with them .Previous owners didn’t want too spend good money on maintenance
This is why I own an SL. Jk, good luck with the repair, don’t give up!
Ask the throttle guy that if you can👌
When I had a walbro on my dsm it wined like that all the time.
How’s the MAF sensor and knock sensor(s) ? My 2g would buck under accel ended up being the wire to the knock sensor had been ripped off when I did the motor mounts. Clean/replace the MAF sensor, crank position sensors, cam sensors, might be a start.
Both have been replaced at some point but I’ll check over everything again. Thanks!
I have walbro 450 and you can hear it from behind when car is running. If you have fuel pressure and it is not dropping out when revving car then i would suspect something with injectors. Whether it is the resistor pack, bad connection, or dead injector. Even though you replaced them doesn't mean they are still good and working. You cannot build fuel pressure without flow so if you have pressure then fuel is flowing.
Thanks for the insight!
Just throw it out there connected to your fuel pump I see a spliced wire check the splice make sure it’s connected right and then I’d check your injectors make sure they are plugged right
my 3000gt just gave me the same problem a week ago & stop running
Bro try swapping out your o2 sensors.. work for me just saying
The relay could be fried at this point I mean it is like a 25 year old car. Wouldn't hurt to check
Hey buddy, off subject some, can you do some 1g dsm love on the race legacy apparel?
hey I saw your friends ferrari 360, idk what transmission it has but if an F1 auto my we make manual swap kits for ferrari 360 and f430 models
Why you dont put an other ecu in? An Emu or haltec or something?
Because I’m not rich and can’t drop thousands into a stand alone Ecu and tune just because
Might be time to invest in a truck n trailer friend i learned the hard way
My thoughts are that the fuel pressure regulator is the issue
Have you tried unplugging the MAF and doing a drive? Lean AFR and drive ability could be due to that.
Also make sure the AFPR isn't a bad diaphragm. I've realized over time the quality of fuel rends to cause some slight corrosion and would cause the ball not to seat properly (though mine wasn't aeromotive). All AFPRs usually do drop to zero, though some take longer.
Pinch the return line as you shut off and see if the pressure holds. if it still drops fast, pinch the feed as you shut off and see. That may better tell you if it's injectors.
I’ll check it out! Thanks for the insight man! 🙏🏻
I think something similar happened to my 95 VR-4. My car would idle fine then just cut power in intervals under acceleration. When you're giving it light gas, are you hearing a click and seeing an immediate drop in RPMs, as if there's an electrical issue?
I keep watching these videos and I’m still a little new to cars but what does he mean by flashing the car?
Ecu/computer gets new Information on how to have the car run based on any changes done to the fuel system or added modifications
Ive heard my Walbro squealed once or twice on my 8 about 3 years ago. Went away never returned. Could your problem be clogged IN-LINE fitler. I think you should datalog it.
Hey Miguel if you don’t mind what do you use to record
Miguel what camera do you use? Like what setup, and how do you edit the videos what software? I might start a RUclips car channel too, good side income too
I use the Sony a7s3 with Final Cut Pro
I had to double check the title, damn im sorry man just dont give up!
All good! It happens
Where did you get your side skirts and front lip?
FWIW, my VR4 doesn't hold pressure when turned off and no drivability issues
Are you back from TJ?
Where can we get that carbon fiber combat wing.
question did the 420a came with a turbo model and if it did which dsm model came with the turbo 420a
Why are you running such big injectors? Do you have upgraded turbos? Or are they the stock ones still
Stock turbo 750cc injectors to replace the faulty oem ones
Skrrt skrrt.... oh wait, there wont be any of that.... oops
Not today 🤣
this is happening to my vr4 too I'm going to replace the mfi relay have you tried replacing the mfi relay the oem one maybe thats it. its on the passenger side carpet panel. because i cant accelerate too much or else it sputters. (Update on my vr4: it wasn't it I feel defeated too now :(/
Are you using ECU link on it what are you flashing with?
98 ecu with tatrix cable
To bad you can't get 93 octane.
Question about my 97 GST. When I accelerate and it gets to 3k , the car jerks and doesn’t let me get on it. Any idea anybody?
these cars are most known for unreliability, Cool cars! But gonna be chasing issues forever.
I know how to fix all these problems!!!! Just 4g63 swap it! Lol
swap out the plastic from the one in the car to the other.
Anybody interested in a 97 with a 99 conversión for 25k? Has a new paint job and everything
It's a vr4
First :)
I’m going to look at a 94’ Vr4 that just had the whole top end rebuilt this weekend, I hope this isn’t my sign not to buy it 🥲
