Definitely worth checking the spark plug leads; my series 1 RX8 was difficult to start and all it turned out to be was one of the spark plug leads had came loose! Great channel by the way!
How the hell do you only have 2K subscribers? You make awesome and helpful videos!
Thanks man ! :D They are lost on the internet somewhere... if you want, you can share my videos so more join the club :)
Driven by madness will do!
30k now
Exactly the process I went through with mine. I replaced the battery the day I bought it, in fact before even driving it home. As soon as I got it home and bought the parts, I did a full ignition replacement with coils, wires, and plugs. After that, I replaced the starter. While I didn't ever check the relay, after pulling the engine and disassembling it, I found that the apex seals were less than half the height that they should be. That's definitely low compression right there lol.
Damn, now that's a hardcore process :D I'm glad it runs fine now. This is just one of those things you have have an anxiety till it happens, and after it, you feel like a weight has been dropped, and how you can enjoy it with no restrictions :D
I'm in the UK and I ordered BHR coils for a fairly reasonable price. Can't wait to try them out since they don't need the d585 adapters but use the d585 system
Love these videos man, im trying to buy one myself, great info.
Hard Dreamer Thanks man, good luck with you search, maybe the rx8 is closer than you think 😄👌

Nice summary Kris!
Anyway before wasting money on coils and starters check the compression.
If the engine has not enough compression all the other things might help but you are just wasting your money that you could use for a rebuild that will solve the true cause of the slow starting problem!
Keep the videos coming
Thank Bill! :D
Technically, your method is better, but for new owners or less experienced ones, it's psychically easier to do it my way. Because i've noticed with all the messages i get, that people want to resort to compression tests only as a last resort. Hopefully i will change this with my future video projects :)
"people want to resort to compression tests only as a last resort."
And that is the problem!
You can do a compression test for around 20 bucks yourself with some simple tricks. (ill send you a message tomorrow)
If you can change your spark plugs you can do a compression test.
It is not a hard task at all and you will know if you have a real problem before desperately trying to overcome it with multiple small useless repairs.
It might safe you hundreds of Euros if you know that the engine is toast.
Please do not see this as critic to you but to the people who make a rotary compression test look like dark art scaring people of.
Good night :)
Great info man, meine deutsch mekanik ist uber alles! Thanks, i'll gladly wait for it, night :)
@@hillbill3502 "too low compression" ho much is a too low compression? I know under 5.4 bar the engine is not in great shape, but WHEN is it time to think about rebuilding it?
One good way of testing the coils is while started on the road check how easy the rpm increase from low rpm to sudden full throttle ... I didn't pay attention to mine but once the mechanic said it could get better and test fitted the Hitachi one I knew the difference not the best but better, if anyone has the money go for aem one or msd it's gonna worth if it saves you from rebuild
Such a complicated car but such a lovely car at the same time
I agree 100000% :D
Man you are very cool! Thank you for your videos .. Greetings from Russian fans of Rx-8 ;)
Thanks man :D A big high five to my Russian friends!
Hey guys, chris fix of rx8s here
Matthew Murphy I Never stop dreaming 😄👌
I was thinking of that as well. He is the chris fix for the rx8
Hey my rx8 won’t start can you help?
Thanks for all your great videos man. Next could you make a video about how to set the idle on the rx8 after disconnecting battery?
Interesting topic, i will write it down and do it in the future :) Thanks!
Start car. Pump brake pedal around 20 times. If DSC light doesn't shut off. Turn wheel all the way to the left then all the way to the right and back to center. Cycle ignition. Start car idle should be better. Will have to drive for a few drive cycles and the PCM relearns it's fuel parameters
Great videos!!!
Driven by Madness my old friend, how are you? :)
I'm glad you came up with this Video thx for that, because now I have the same problem. up coming week I'll change my spark plugs first, hope it starts better (they are really old) then I'll see.
like and support from Germany ;)
What's up man :D Awesome, hopefully this will solve your problem, so that you can go back to enjoy your rx8 :)
Thank you so much
Driven by madness I hope it's not the starter engine, how much I would pay for a better one?
mine was cca 80€ + shipping cca 15€, not that expensive. The same one should be linked in the description :)
Driven by madness thx a lot m8 :)
You're welcome bro :)
What country are you filming in? The scenery is always amazing!
love your videos you’ve helped me do heaps to my RX8 is the starter motor an easy fix? would i need any gaskets?
It's quite easy and fast. I also have a video that shows you how to do it: th-cam.com/video/vgIhxFU-nGg/w-d-xo.html
Driven By Madness you my friend are a legend, battery drops down to almost 5/6 volts on the multimeter, i will start with a new battery 🤞🏼that’s going to fix it
@@richmalloy6174 super, glad you found that out 👌
How much is the starter engine relay? I'm curious if that's just simply worth replacing every 10 years??
I very recently found the problem for my slow starts. I had a cracked starter relay, a bad positive terminal, and bad spark plugs, all which killed my new-ish battery. Talk about dominoes falling 😤
Cleod9 9M ohhh jesus... well, at least you found the issue 👌
Great video! Very informative and fun all at the same time.
Thanks for the tips man, I have trouble starting it up. I will try all of these!
Awesome! Let me know if they helped :)
My 2009 RX8 has trouble starting on its own when the engine is already warmed up - modified the cooling fan & new battery but I’m still having this issue - any tips good sir?
Bro, I love the vid you've been doing on RX-8. I followed ever since the first time you have that red beast. I have a question, is having an RX-8 in your life difficult to take care compare to other cars like polo or something? Cause I'm still a student and I wanted to buy one of this. Base on your vid, all the maintenance I can just DIY myself so I need your opinion for this. Please and thank you
Faris Aiman these cars are very simple to maintain, just do regular oil changes every 3k miles and keep 2 or 3 quarts of oil in your trunk and check your oil every fill up and top it off as needed(the rotary does consume oil), use premix, and a redline a day keeps the carbon away. The one thing I recommend doing before buying any RX-8 is having it compression tested, if the compression comes back good, just make sure your ignition system is up to par and you have a good battery, and you're all set! RX8s are not very hard to maintain and require very little outside of what you would need to do to a regular car, they just will fail if YOU fail to maintain them. Skipping an oil change, not topping off your oil as needed, not servicing your ignition, etc. it's not a Honda, but it's definitely not "unreliable" if taken care of
Well said All Things RC. The rx8 is extremely easy and not expensive to maintain Faris, but don't skip maintenance, because fixing it can get expensive. I'm also still a "student", and you'll be able to manage. But i got a scooter as a daily, and i suggest it :)
wow, you helped me a lot with this kind of information. thank you and hope I can get this beast one day haha
you compare a hot engine start on 2:37 (as example for a bad starter), with a cold engine start on 2:43, as an exemple for a new starter? Realy?
I gotta 04 RX8 about 143xxx miles now
Still runs like a champs
Just wondering if they sell a newer starter for the automatic rx8 because the original starter is kinda weak please let me know
Yes they do it’s on Amazon too
Just bought my rx8 it’s a 2006 shinka & it takes a few seconds of crank to start maybe close to six 6 what should I do I try not to replace the motor car the motor seems to run fine & I was told it has ls coils also my oil temp is not at middle a little above & my engine time is a little below middle
Would you recommend a higher amp alternator?
So I have a 2005 rx8 and I just replaced the starter after my car sat for 6 days and now it will just click and not roll over what could it be ?
Great video again, and I love the music! But could you elaborate on the starter relais issue? Isn't it better to just replace the relais and see what happens instead of bringing it to a mechanic?
The issue is not the relay, but the wires sending power to the relay, and from the relay on. This video better explain the issue :) th-cam.com/video/JfjhVfLcflo/w-d-xo.html
Ah ok, now I understand :). Will you also do a video on the battery reset issue of the 2004-2010 Mazda's? I don't know if you have experienced it, but there is this common issue that the car won't idle or will idle roughly after you have disconnected the negative battery terminal for quite a while (or basically, disconnected the battery). There is a certain relearn procedure for this, and some say "idle 20min with everything off, then idle 10 min with everything on".
I've heard of this, i'll dig into this and make a video in the future. Thanks for suggesting it bro!
1:43 I dont have a grandma at my place :[ and i dont have any friends
i have an old neighbour lady yelling 'this is not a workshop garage'
and the dog cant reach the clutch and key same time :[
Would you know if theres any specific way or recommended products for cleaning the throttle body on our 8s? I was told mine needs to be cleaned and im curious lol
Any suggestion on where to find a upgraded automatic transmission starter?
Rx8 performance made a few you might be able to find some on the forums.
Hey driven by madness. LOVE your videos! DO you have a video on tips for teens owning an rx8? Im about to buy one real soon and I'm 16. Thanks!
Hey man thank you very much! :D
Straw Hats omg dude, I just realised that my answer was not complete, I apologize for that. Yes, I made a video just on that topic, its called "10 mistakes new rx8 owners make" here's the link: th-cam.com/video/Dg4QNYDhBM8/w-d-xo.html
have a mazda rx8 2006 , ignition is on but no crank , only sometimes, any suggestions?
Mine was starting fine, parked for 4 days, then all of a sudden needed a few seconds of cranking to start. Today, it took 2 attempts then wouldn't start while hot. I'm hoping just my battery is bad (it has gone flat several times) as it seems like it was fine one minute and not the next. I'll try to jump start it and see how it reacts.
What was it
Very helpful👍
Thanks 👌😀
Everyone only talks about rough hot starts but what about cold starts , I have had two random hard cold starts , cranks but doesn't turn on , turns on second time around any ideas ??
Jason ive replied to one similar comment of yours. Check battery, maybe it looses charge too fast after you shut down the car. Try switching batteries, and see if it solves the issue
Been watching your videos since I bought my rx8, my rx8 is not starting, do you have any solutions?
Check out my fidn and fix section: www.drivenbymadness.eu/find-fix
Dee Jay, thanks, I got a new engine, the last engine had a blow gasket, but loving the rx8
My car starts very well and drives very nicely! But when engine hot, it’s a nightmare to start it... as if the petrol isn’t injection well, after few accelerator pedal, it kind catches it and slowly launches the engine..
thanks man!
You're welcome :)
that beat on the video is hard
How I can started the car flooded??
I have a fix for a weak compression RX8. This will add several thousands miles to a rotary that is considered worn out.
Take qty. 6 Maxwell 2.7 volt 350 farad super capacitors. Put them on a balancing board and connect them in series. Then connect this parallel with the battery. This device will spin a weak rotary like a sewing machine for about 10 seconds. When I did mine it always started hot or cold.
My rx8 won’t start after a friend turned it on and off simultaneously, just charged the battery. I feel as if it was drowned, should I change the spark plugs ?? Any recommendations will be appreciated
Does it make some noise when turning the key?
Does it crank or just silent/fast clicking?
Hello, how do i know if my rx8 (2006) have the 1.4kW starter or the 2.0kW one ?
Take it out and count the teeth. If it wasn't changed, it's still the original. Original starter has 11 teeth, 2kw one has 13 or 14 teeth :)
What about automatic car
I need to check on that, because I have start up problems but also AC problems. Whenever I drive with my AC on my car will cut off on its own and then I’d have to hope I don’t get hit and it starts again😂
Cool videos thank for the info
My car sounds like the before clip but it starts off slower than that but is overall faster to start timewise
I have to keep my rx8 reved up when I first start it until it warms up or it dies ... then it still has rough idle but stays on. Any help ?
Clean MAF sensor, Could be old worn sparkplugs, if you have't changed them in the past 5 years, change them
what year did the starter motor get upgraded?
2006
Driven by madness thanks
You're welcome :)
Does the R3 face the same symptoms and problems??
Yes, the difference is a better starter on the R3, but can still be worn out, but it's less likely to happen :)
Driven by madness ur the man! Thanks man. one other thing have u done a video on the start/Stop procedure for the Rx-8?
Yes, it's in the 10 mistakes new rx8 owners make video, here's the link: th-cam.com/video/Dg4QNYDhBM8/w-d-xo.html
My start up is amazing.. but my idle studders just a little... not close to stalling at all..but annoying
Nice haircut! 😄
Thanks! :D This is the "summer slav hairstyle" :P
Were I can bey links fore my rx8
You have links in the description of the video :)
Thanks:)
you're welcome :)
I have a highly serious question , my rx8 starts up fine when I haven’t driven it ; but after four miles my car won’t want to start
THis should help: www.drivenbymadness.eu/find-fix
So what happens if I leave my car lights on for three minutes but then there’s no power at all to the car ?
Derek Ramirez then your battery is dead.
the coils link for the USA doesnt work anymore , btw....
Thank you for the feedback. I'll update it as soon as possible
Has your engine been rebuilt?
yes at 62.000 km. Now i have 120.000km and my compression is around 6.5 Bar
Isn’t 6.5 bar quite low?
Are you original owner?
Thanx i will do battery first then starter coils and plugs
Nice video
About how much does a rebuilt cost for these cars? I'm having a long star like about 4 or 5 seconds I will check these problems first but in case it's because of the low compression aobout how much money I'm expecting to spend?
Very informative video 👌👏
Thanks! Rebuilds cost around 2500$
are you in Slovenia??
Seveda da je
Crossing my fingers my coils and plugs are still good..
You start the car when hot, with the old ignition and then with the ‘aftermarket’ one you start it when cold (check the oil temperature when he does it). So that we will believe that it does work
"You want to replace all three of them,"
starter change is not true, you compared hot and cold start....
Aleksandar Stanic in my case both cold and hot were the same. The hot/cold start mixup was an edit error. Here's the original video, so you can compare them 😉 th-cam.com/video/BJdFvPD13V8/w-d-xo.html
your car was cold when starting with the new starter so its going to be easy to start
KillerDinoz you can check out my starter replacement video. and you'll see the hot start too :)
Mazda rx8 owners are a small percent of society.
The headlights looks awful but the rest of the car is awesome!
I agree, i already cleared them with the kit, but after 3 months they get bad again. So i'm waiting to buy new ones :)
Driven by madness Try buffing with multiple compounds. I've restored multiple sets of headlights with buffing and they come out looking brand new.
I already tried everything, but either after a wash they get slowly back to being shitty, or fade with time. I'll try to sand them down again and spray clear coal on them. I've seen a body shop do this and the end result was amazing, they looked like new, and they last for years :)
Yes, it's hard to beat urethane car clear coat.
The polishing looks good a few months to a year.
A couple coats of 2k urethane clear and it should be good for about 5 years.
turn off music so we can hear the starter. just a thought
"Get a friend, or your grandma to start the car"
I would rather sell the car
Why not just swap an engine?? Common sense
👀
First comment.
Where's the noti squad?
Sleeping :P
Driven by madness lol
ls swap would fix all rotary problems
You could please not put these shit songs... Thanks for the videos.
Marcos V. B. Ive dropped them a long time ago. Newer videos are just talk & work 👌 thanks 😊
