It'll make more of a difference than having the car sit and wonder what's wrong with it lol.

True. What a PITA.

I'm going to be doing my valve cleaning soon as well. Never done it before so I'm gonna try and get some Nator guys to help, but either way I'm following this thread because my noob ass could easily do something wrong.

It's a good thing if you can get some knowledgeable people to assist. I did it solo and it's no walk in the park. I installed an EGR block kit and an oil catch can because it's my understanding those things will help keep the valves cleaner. I dread ever doing that job again.

I'm having some similar issues, but took a different route to get there. Figured jumping on here and sharing info might help us both.
I got the zoom zoom boom last month, and finally got everything hooked back up and double and triple checked that I didn't miss anything. So new long block, and while I was at it, turbo, intercooler, and fuel pump. Go to start it up, took it some time, but finally got it to fire, but would only last a couple seconds before dying off each time. Had it going long enough, I got a couple codes. P0123, P0222. Thinking it was something in the area of throttle body. Took it all apart, everything still looked good. Checked again for nothing loose. Still same results, running for a couple seconds and gone.
Searched the forums for a couple hours and picked up the idea to unplug the MAF to see what happens. Started like a dream! Let it idle for a while, as the rpm's dropped to normal idle, it struggled (expected with no MAF). Plugged MAF in and the it died as before. New codes this time, P0102, P0113. Once again, kind of expected with no MAF.

The MAF wasn't touched besides unhooking, and reconnecting, through the whole swap, so I'm saving that witch hunt for a minute. I know there are issues people have had with its wiring. I did check all the fuses and looked good. Tomorrow I'm going to try calling my tuner to see if he knows of anything, thinking it may be something that the ECU has some relearning to do, or if they have seen the issue before.

Best of luck to you! And I'll definitely update if I get any success.

[Djohns]

I just did the valve cleaning last week, along with turbo, manifold and injector seals and I'm not gunna lie your thread made me scared to start my car when I finished all that lol.

[Chinchilla Dakilla]

Hell... I'm getting scared to even do it.

This maybe very anti-DIY of me (and I will probably get flamed), but what do the average reputable mechanic shop charge to do valve cleanings?

Honestly it's not that bad, OP is just running into a bit of bad luck. However I will say I actually don't recommend using b12 because that actually makes the carbon a little harder to remove because the media blast sticks to it. I didn't use any b12 and I think it took me 2-3 hours to remove manifold, blast valves and reinstall manifold.

So do it without using any B12? Just the Walnut shells only?

B12 makes the carbon gummy. Walnut works better wheb carbon is just dry.

I left the b12 in overnight, 2 different nights, and it eat the carbon up pretty good

Correct. Also it doesn't hurt to to scrub the valves with a metal brush. I used one of the brushes I have that are meant for cleaning the barrel of a gun. Works great. Also be sure to be vacuuming the valves while you're spraying.

My very first Nator meet we did someone's valves, but that almost 3 years ago and my first time ever digging really deep under a hood so I don't remember much.

What I do remember was using a shop vac and just taking some plastic tubing and cutting a small slip close to the end of the tub that goes into the intake valves and then suctioning while periodically spraying from different angles.

We did use that liquid (seafoam I think?).

I remember that on one of the valves we didn't put the piston to the top so some liquid went into the engine. Not sure what that would do.

It'll burn off, create some smoke at start up.

Sea foam isn't all the great, it's been proven to not do shit on our cars. Using a liquid, some people like and some don't. I prefer not to use it because I don't want to drag a simple valve cleaning out for a couple days just so I can soak the valves. They clean up just fine using dry walnut.

[Chinchilla Dakilla]

I will definitely only use the Walnut shells then. It may take a little more time, but someone did say if you use the liquid that to do it "properly" takes about 12 hours.

FYI - not sure if it matters, but my car is getting close to 90k miles and I have never cleaned the valves. I've been the only owner.

Back on topic though, @attomica; were you able to do any trouble shooting today?

For the peace of mind, yes. Pulling the spark plugs just to check them in case they became contaminated with some of the leftovers during the clean would also eliminate a few things from the list. If you had a leak from some disconnected hose or from fitting the OCC incorrectly the car would run for 5-10 seconds every time you try to start it and only then shut down. While because yours doesn't start at all having the spark plugs fucked up can make sense.

Also, disconnect the battery for a minute or so, connect it back, and try to start the car in case the ECU learned something that would prevent the car from starting.

Before any of the above connect your AP or versatuner to the car and see if there are any latent codes in the ECU memory. You can have codes in there even if the check engine light is not on yet.

Funny you should ask. I just got home. I have to confess...I just got tired of the problems and didn't want to wrench on it any more, so, with great hesitation, I took it to a dealer. Sigh. Yeah, I know...bad juju, but I lucked out and it worked for me. Turns out it was just a loose ground wire.

I dunno what to think. Was it gonna start all along and I just didn't crank it long enough? Was it flooded and they just cleared it out? Who knows? I'm skeptical, but that what they claim was the problem and my car runs like a top now. Also confirmed I did everything right. Well, except knock a ground wire loose, I guess.

So, semi-expensive lesson? I dunno...make sure ground wires are in place and properly secured.

Anyway, I'm super grateful for all who helped me out. Even if your suggestions didn't work out, it was a good feeling knowing I had SOME support. The TN/KY NATOR pretty much just uses Facebook and I don't do that shit, so I'm out of touch with anyone who could've helped out here.

Wow, it's amazing how something so small and simple can cause hours of headache.

At least she's running like a champ now.

If you don't mind me asking about how much was that bill?

No, it's more toward the bottom of the TMIC. I'm not sure how to describe it.

Agreed. Still, I don't ever want to fuck with those damn valves again. Total bill was $270 which included the tow, the diagnostic fee and the decorative Mazdaspeed kickplate I ordered to replace one that got screwed up.

I do have to say, the valve cleaning, new spark plugs, and the other stuff I did made a noticable difference. I haven't really gone full boost because I need to change the oil first, but on the little drive home from the dealer I goosed it and was actually suprised by the response. I'll change the oil this weekend, button it all up, and get some road time in to really tell, but I'm excited at the improvement in performance.

Anyone thinking about doing the valve cleaning there is a diy with good directions. It specifies this ground near the hpfp and how it will cause a no start. I should've remembered. Don't let it intimidate you

This makes me sad. This is the post I have saved to perform this myself. At least we have the corksport guide for the seals and some drunk guys encounters to go off of on YouTube. Maybe when I flail like a limp dick sea lion (no idea where that came from haha) illl take some pics... not of the sea lion btw

When you did the spark plugs, did you twist the coils back and forth and make absolutely sure it snapps into contact with the spark plug. You pulled the spark plugs out and they were dirty even being brand new and the car had never ran? Sounds like the car is getting fuel but it's not combusting. Or doing your OCC a massive vacuum leak was made. Check your PCV to OCC, And your valve cover breather to your OCC, and your OCC to your turbo inlet pipe. Also we need to know the process you followed to clean your valves, for all we know you followed incorrect instructions. Any questions glad to help man I feel for you

I'm grateful for your suggestions, but I did all that correctly. Look a couple of my posts back and you'll see more details about discovering the problem was just a loose ground wire.

[Djohns]

Shit! I too thought about that ground since that little guy tends to get a lot of people but that shouldn't have been messed with for the jobs you did so I didn't think that could be it.

[darkmx-6]

It's kinda like what is happening to me but I haven't tried to start it. I just have to wait for parts. I broke the small nipple on the turbo inlet pipe while cleaning the egr which wasn't that dirty to being with and probably isn't going to clear my code... *Sigh*

[Austrichh]

So not to hijack a thread but I'm wondering if when I pulled my valve cover to replace a random ass bolt the PO put in instead of an actual valve cover bolt I might have knocked something loose. Car cranks but won't start. It ran for 130 miles after I out everything back and then wouldn't start for a week and I went back over everything and it fired up for two days and now zilch. I have another post with people helping and my local buddies and my tuner and noone can figure it out.

My thought is you have a ground that's working intermittently.
