The Built Subaru STI's First Start...(Ends Badly)

[@bratface90210]

That code is for the primary circuit of the coil, which is the PCM control side. By swapping the coil with another cylinder you eliminated the coil as a fault. For that code to set there has the be an issue with the engine harness, or the PCM. I know the description says primary / secondary on the access port, however no PCM anywhere can tell the condition of a secondary concern in a coil as they're not electrically connected.. I would look for wiring that might have gotten pinched or rubbed through. Make sure your pins in all the connectors look good.

[@johnviersma2036]

Second this, you eliminated the chance of a hardware problem so it is most definitely an electrical issue. Check for loose pins/connections for an open and pinched wiring where it could be shorting to ground. Try wiggling the wiring with the car running to see if the misfire stops.

[@daylinkapec-allen7044]

This same thing happened to my buddies rebuilt motor. Turned out to be a wire got slit on reinstalling on the harness. Constantly losing connection strength

[@iitheguardianii5377]

Exact same issue after building my brothers motor! The connector was replaced a few years ago due to rodent damage and the wire inside of the wire connector was severed causing the same code to show up from time to time. Really messed with me for a few weeks since it was so random when it would kill a cylinder. (I also had the same reaction every time it had this issue and by the time I got back to the house it would stop).

[@XxCrAzY509xX]

Wouldn’t the car throw a high circuit or low circuit code if it was wiring related ?

[@iitheguardianii5377]

@@XxCrAzY509xX The code is pretty generic as it sets for a circuit malfunction which would include wiring being the potential issue as well. At least that's how I see it.

[@sergiopassos376]

This guy's pulls engines and rebuilds them before I could swap headers lol 😆

[@thomasmurphy5906]

And before I can change my timing belt

[@ghostperformance801]

When you have the time and the money to afford the parts it makes it easy to build things in a good timely manner only hard part is waiting for the company’s to ship them out

[@rotor13]

For real. My daily beater threw a timing belt and this guy built a forged block inside a week, while its taking me over 2 weeks to do this timing belt job lmao I need to invest in getting insulated doors for my garage and install a/c. Even working at night with the sun gone its ungodly hot and humid lately here in Texas with the rain i've gotten.

[@Geeoh392]

“You better humble yourself, these subaru’s made you famous.” 🤣🤣🤣

[@_J_U_S_T_I_N_]

No bullshit, my day gets instantly better when Devin puts out a fresh banger.

[@OwningZombies101]

facts

[@hiphopdancerjeff]

check connections with a multimeter, could have crappy wires connecting to the coil

[@shandreroji3786]

How many youtubers build their own cars? This man us brilliant

[@gordyboy01]

If the misfire failed to move from the fourth cylinder after swapping coils and plugs, which you have already done then like others have said here, you know that you most likely have an issue with the wiring harness going from the coil pack to the Subie's PCM/ECM. Take a look at where the harness plugs into the coil pack. Is it damaged or loose feeling in relation to the other cylinder’s connections? If so it may need to be replaced. If the misfire is intermittent, go ahead and jiggle the wiring harness and see if it has an impact on the way the engine is running. If it does start or stop misfiring, you know you’ve found your problem. Look anywhere that the harness bends or touches anything sharp. Look to see if it looks burnt anywhere. Check for damage and repair the wiring accordingly. check your grounds. Good luck

[@qhivitiva3823]

Log intake and exhaust avcs and compare left and right. Car probably idles fine when cold before avcs activates and the misfire starts. Open the lh exhaust cam gear cover and check that the spring is still in place.

[@Silbaru]

I really appreciate you doing the daily videos again Devin

[@PastorOfMuppetsVIVIVI]

Dude needs a break.

[@joshbrown384]

Damn, 3 days in a row. These uploads made my whole weekend

[@DJ_Driven]

Use good old petroleum jelly Vaseline to prime those oil pump gears. Sheedia ran into the same issue with his EG33 build.

[@DJ_Driven]

Check the connector and or pins leading to the coil packs. If they're bad Iwire makes repair kit.

[@Blue450]

I had ones an issue, that they put me wrong Plugs into my vr6. When the engine was getting warm i had missfires - try to change the plugs. Besides, thats the only thing you changed.

[@jonney8046]

When you rebuilt those cam gears, there is a chance upon reassembly that the bolt on plate is not within the concentricity tolerance to the bore that the cam shaft slides into. They have to be pretty spot on, which I think is why Subaru considers them ‘unserviceable’. I know outfront uses a alignment tool they machined to align the parts when they rebuild them. Not saying this is definitely causing your issues, but might be a good thing to look into if all other possibilities are explored with no solution!

[@blowngemini2031]

Your spot on there. You can align them using a inlet cam on the inlet avc and exhaust cam on the exhaust avc. You need to set the camshaft in the avc then tighten the 6 bolts. Also make shore you put the6 plastic waves and metal springs in the right way they came out. I rebuilded my avc and havent had a problem have done over 5000km since full rebuild.

[@scoobdoo4233]

Exactly what I was saying in my above comment I love your content and always watch I'm a tech myself and when I see you stripping them down my first thought was that's gonna be a problem on start up so been waiting now all these issues my guess I would start there as your a confident tech but them things are tech classed as non servicable

[@rockytopridr7463]

You can take off the oil filter, turn it over with the sensor unplugged and that usually does the trick for hard to prime ej's.

[@craigtrigg4288]

you work so dam hard on cars i know how you feel i love your both channels / bobbi channel too

[@DP-rl5xj]

Hi Devin . Please don't stress Yourself, it will be an easy fix tomorrow, when You find it.. Keep up the great ethics - You'll Win in the end. From WLG NZ..

[@blowngemini2031]

When rebuilding the avc i notice you didnt look at which way the waves went in and also you needed to set a cam shaft in the avc when bolting the avc. Be careful as not setting them right you can strip the cam pins on the camshaft and the pulleys.

[@_robertburger]

Hey Devin I’ve never packed a Subaru pump, and can always build pressure with brand new motors. If they don’t build pressure from just turning over, which I’ve had some not, pull off the oil filter. Then turn over until oil comes out. There’s a passage straight above the filter that is closely tied in with the pump. It can get air locked. When mine don’t build pressure, I do that, and it always works Hope this helps.

[@Turb0.On.Wheels]

A little trick that I use when priming a new engine before first start - remove the oil filter and prime until oil comes out from the filter connection. Put the filter on and prime until full oil pressure.

[@alengreen589]

don´t give up bro, everyday you learn more.

[@giovannicorona9163]

Swap injectors had a similar problem

[@GhostedPerformanceCF]

I'd honestly re-check your grounds. If it's that side only. They may look good but sometimes tuna with no crust may still be crusty. Had bad idle issues with my subaru. Cleaned em up and I was golden. If that doesn't work I'd check the ignition coil cables with a multimeter. Make sure it's spitting out what needs to be.

[@twtng]

Devin is my inspiration whenever i do even simple work on my bike.

[@adamagag1311]

Appreciate your work ethics and wishing you well on your health Devin. 🙏

[@brianwambua5978]

Great to have the frequent videos back.

[@benardojambojr5030]

@Devin thanks for everything man ur ma no.1 stress healer actually when a we starting the N12 content Ben from Uganda Africa...

[@wraith6437]

I was throwing that code on #3 before I had fuel pulse dampeners......hope you get it sorted dude

[@imchillin24seven]

My guy 3 in a row . We appreciate the daily's again!

[@newjerseydamo]

I know I shouldn't laugh, but you're so wholesome and down to earth. That's why I enjoy your content. Don't let it get you down and look forward to the next vid!

[@longdomedia]

Nah you just need a flat 6 subie in ya life 😜 smeedias VA is going to be a monster

[@scoobdoo4233]

I'm gonna say its the avcs pulls you stripped you need proper alignment tools to align them up if not the stick and can affect cam timing and possible misfires.i rebuild my engine and just washed them out I would not attempt to rebuilt just look up tort performance on youtube

[@MrRafaelbsypher]

Stay positive homie ull get it. Just look where ur at now, big shop, a lift. Too much blessings to list. Love ur channel. Now go back to more Mitsubishi ish

[@kieranhorner1282]

Test the wiring harness and your ground connection

[@peterdavies7977]

Chin up Devin, you the man!!!!!!

[@thebiggestboy6614]

Keep your head up Devin, you’ll find a way to fix it And you’ve never made a shitty video we love all of them 😄

[@AWOL_ODST]

Devin’s EVO vids are either educational or action packed. The Subie ones are more like Comedies, laughing my ass off 👍🏻 Sorry D, feel your pain but it is entertaining to watch 😂

[@chrisbaines9206]

Dev take a deep breath my guy let it sit for a day or two then go back with a clear mind... Wrenching on motors can be a PIA but we love it... As stated below start diagnosis at the part of the harness if you can. Hopefully you can get a good look at that area easily. good luck chief..

[@stevebarkey1452]

Best time of day is when you post a video,really appreciate what you do under the circumstances, hope you sort out your health issues.

[@grandgt00]

Check the fuel injector on that cylinder with an ohms meter. make sure it’s not bad. Had miss fire on my car change everything I could think of and all long it was a bad fuel injector.

[@FutureWarCultist]

I know what our vocabularies become when codes flip on/off. There had to have been massive edits 💯

[@Joshtera]

Boxer engine is very interesting, first time really grasping the concept of how it works

[@brandonpetrilla1731]

Seems temperature related, Do a wiggle test when the engines acting up on the coil wire harness and see it the misfire clears

[@VehicleSensation]

Daily Videos Much Appreciated Devin

[@maddtech348]

Check the wiring cud be a cut wire or rubbed thru or a short. That's where I wud start if its jus throwing one code for a coil. Good luck man you will figure it out you always do

[@agutierrez94]

Another banger man appreciate the videos 🤙🏼

[@NunYaBeezWax80]

My Mustang had the same issue. I damaged the pigtail when i was replacing spark plugs. I might have pulled it a bit hard. The issue was so intermittent. I would run good for a while then start misfiring again. No more misfires after replacing the connector to the coil pack. Or you can get a new engine loom.

[@Hablackboii]

sorry for the confusion bro youll get it sorted always do

[@_zhivkovski_n]

Hi men,i really appreciate your work from most of youtubers you rock men.Keep the good work.👋👋from North Macedonia Europe

[@Jerry-nz3ji]

Your issue with the coil D is going to be in the wiring harness to the coil pack after moving the components and it stayed put. Start looking at the harness for breaks in the wiring or faulty grounds, etc.

[@customcarsdetailing2038]

Good to see you back Devin . I know you will Figure out what’s going on stay Healthy my man keep up the amazing work 👌

[@DC322]

I feel you. Trying to solve the problem and it keeps on doing it. I get mad and frustrated when something is not fixed.

[@111Slickrick]

Literally just had the same issue and code just for cylinder B after engine replacement. It ended up being the engine harness bulk connector over by the brake hydraulic unit

[@ashishpatel350]

The Hatch is nicest sti made. Always loved that look

[@williepie]

check the coil connectors and clean them with maf cleaner

[@soccer1404]

Had a problem similar to this but on a Nissan with VVT and one of the Notches in the cam Phaser was broken causing it to misfire.

[@jpar196]

had a similar issue when I did some spark plugs once on a sti, ended up being a dodgy connector/connection to the coil pack rather than the plugs or coils them selves, as it was running all good before. once the connector was sorted misfire went away as expected.

[@bijanimandoust5418]

Maybe check the pins on the coil connector for D location? That seems to me why when you switched coils the code didn't select a new cylinder. 🤔 but I'm a VW/Audi head so what do I know ?

[@trentonkingsley9422]

The drop is actually 11 am PDT on Saturday. Not 11 am PST. Daylight savings time started in March. Don’t want everyone to show up and hour early just to wait for an hour lol

[@billyjoegreen239]

Keep up the good work dev

[@_Machine631_]

i feel devin on so many levels. I get the EXACT same way when im working on cars and they never want to cooperate. I start getting pissed and cursing non stop. its for sure something simple. My guess would be a ground signaling issue. if it was intermittent it could be as simple as the pins on the connector not fully seated. Had a similar issue with my fuel controller on my bike. chased the issue that was off and on for months. unplugged it and looked at the pins and one of them were pressed slightly out so it would make intermittent contact.

[@fs0c1ety_bs92]

Or u burn the coil circuit inside the ecu after mixing the connectors

[@PleadTheFifth_Racing]

We've all had days like this, part of being a car guy. You'll get it sorted out!

[@kearinburgess673]

Check the connector plug I bet there’s a brake in the wire
