Can't believe this $5 fix is what kept me from starting my yata. Thank you so much for your straightforward videos!
Glad I could help!
I was trying to find out how to fix the same problem as yours about 2 years ago, now I know how! Thank you very much!
Glad I could help!
Thank you for this video. I replaced the ancient battery in my 1995 Miata, but the headlights were the only thing that worked. I followed your instructions, replaced the fuse, and it starts right up. I jumped the car over and over again and it blew that fuse just like you said.
Good video. Right on the point. And, yes, I did blow my fuse by jump starting.
Thanks was boosting mine and crossed the cabels and blew that fuse . I broke it trying to get it out now i know why . Ill go to mazda tomorrow morning buy a fuse and hopefully be all good thank you again.
Thanks it was an $8.00 fix . I appreciate you posting.
this was very helpful i was so unsure as to why my car wasn’t starting so i decided to change the fuse myself after watching this video and it started right up. Thank You ❤
Fantastic video. You got right to the point, and showed us how to get it done.👍
Literally your video saved us the day!!! Same problem same solution. Thanks man.
Thanks for another enjoyable video!
Thank you. My baby has been sitting for a while as I was saving for a new ECU, which I thought was the culprit. A $6 fuse is a way better fix then a spendy computer
Great video and advice, Thanks
Thanks for sharing; about to go help my buddy with his NA. Yes, he connected the battery backwards lol
I had a similar experience in my 2001 Miata three years ago. It would crank but not start. Had it towed into a Mazda dealership, whose head mechanic had 40+ years of dealership experience? They said it was the immobilizer and would be $2500+ to replace with remanufactured parts from Mazda. I chose to get one out of a recycler and had it shipped to the dealership. They did the work and all seemed well for two days. About $1100 out the door with my supplied parts and their labor. Then I again noticed that when it would crank and not start, that the check engine light would not come on when ignition key was in the first on position! Turns out it was the main relay. Got a used one shipped to me for $12.00. Swappd them out in about 1 minute and it has been perfect for three years! I sued the dealership and got refunded $500 of the the labor. I also bought a brand new main replay to always have with me along with a camshaft position sensor and a crankshaft position sensor which are known to wear out and cause crank but no start situation!
I should also mention that about five years ago I had another sudden crank but no start and had it towed to another Mazda dealership. They diagnosed the problem as a bad crankshaft position sensor. They ordered part. Installed it. Still no start. THEN they replaced the main relay and problem solved. I should have sued them too, but did not.
Other than the engine noise, this car looks better than my ‘92 Miata. It’s hard for me to consider one as good looking as this being a parts car. Love your videos. Keep them coming.
Came here to say the same ... everybody's 'parts car' has better paint/interior than my daily XD
Probably doesn’t have a title. Parts car.
Amazing how one little fuse can disable an entire car. Its sad how the original seller just gave up on it and didn't bother diagnosing it. Oh well, his loss. I don't even own a NA Miata yet but at least now I know what to do should this ever happen to me whenever I do own one.
Great video thank you for that 👍🏻👍🏻👍🏻 gonna change mine today
I have a 2009 Miata-same thing, starter fuse. Cost me $4.50 for a pack of five. Thanks brother!🫡
I shut my Miata off in the front yard and that's where it's at Good battery, lights horn dash lights
THANK YOUUU A MILLION TIMES!!!! My Miata had an immobilizer lol
Great catch!
Niiiice my one did exactly the same thing..... 80amp fuse baby! great vid
Great help, thank you 😊
You're welcome!
Thank you!
Thanks for posting this, I have the same model. I am a newbie. I connected the 12v battery the wrong way, and now nothing works. I was trying to check the fuses and this is very helpful. I was wondering, in this case why do the headlights pop up, I thought that _everything_ went through the 80 amp? By the way, I'm also trying to find my way around the engine compartment. What is that block with the three pipes immediately to the right of the fuse box?
Wish i knew 2x10mm bolts held it in before I pulled as hard as I could with pliers. Thanks for the video!
I just did the same thing lol.
HOWdy N-M,
Thanks for the EDUCATION

Miata man! I need your help. I got ants all over my 93 NA. They aren’t everywhere like a swarm but I know there has to be a nest somewhere. They are about a 1/4 of your fingernail in size and are dark brown. I want to get rid of them so they don’t eat my interior out. Any places on the exterior where leaves and stuff might build up near the front? Thanks.
Thanks
same thing here, out of the blue, had a 20 amper and replaced it, still nothing, closer look that big one shot, but very hard to tell, didnt know about the bolts so now I am ready to attack it
That's really good to know
Will this work with an automatic too? Dash lights turn on, still have power just won't start or crank haven't checked the fuses tho
I think you may have saved me, sir!
Im Having a similar issue with my nb miata it's a 2002 and doesn't have a 80m it has a 100m. Is that the one I should change
Why are these fusrs blowing? And when i got car i installed battery cutoff on battery. So much easier and great theft deterrent
HOWdy M-M,
QUESTION = what is that HYDRAULIC Box next to the MAIN Underhood FUSE BOX ?
my 1993 "NA" 1.6 does NOT have one ... is it ANTI-LOCK Brakes ?
COOP
...
That is the ABS pump 👍
your parts car looks better than my car
So I have a question I haven’t messed much with it but brand new battery, everything lights up and when you go to crank the car it kills everything. You pull the key out wait a few seconds and power comes back and you can try again but same result. The only way you can fire up the car is with a jump. Any idea why it doesn’t like the juice just from the car battery. I didn’t use to have this issue. BTW the main 80A is hard wired how I got the car. Thanks
That’s a weird problem indeed.
Have you tested the new battery?
I've got this issue but the headlights don't even go up or down.
Would putting the positive terminal on battery first cause this? Negative terminal sparked when i put it on and popped fuse (if thats what i think caused it)
What do you think?
It shouldn’t make a difference which one you put on first.
The consensus is to always connect the negative last.
However, it’s safer and easier to connect the negative first on NA Miatas.
If there is power flowing, you will usually see a quick spark when re-connecting battery terminals. Happens on the positive or negative terminal.
You may have an issue somewhere else in the system.
Since you seem to know your way around these things.....I have a weird one for you. 95 M Edition Miata. It won't start unless the headlights are on. Have any idea where to start troubleshooting that one?
I would take a look at the ignition switch as a possible cause.
Our 2004 Jeep Liberty has a parasitic draw. I turns one once it's jumped with jumper cables, but dies completely the next day (no clicking sound, nothing on dashboard...completely dead) If we inspect the large amp in the fuse box in the hood, and see if there's a blown large fuse, do you think it'll fix our problem? Please help, thank you so much!
A parasitic draw can come from many places. It’s usually a faulty component that’s not turning off after the key has. Even removed.
Try pulling out the radio fuse and see if the problem is resolved.
Faulty radios are often the cause of this sort of drain.
@@MiataMan okay thank you! We will try that!😊
I do not know how to reach out and contact you, so I will use this post. I have a 1992 Miata and will NOT start. It cranks, but no start. So, the starter works. Next steps for me are to check fuel pressure and ignition spark. But, I noticed there is an Anti Theft module installed. There is NO model number and no product info. It looks almost like factory installed becuase of the wire harnesess. I am not sure if this module is de-activating the car from starting. Does anyone know anything these anti theft modules?
Thanks for reaching out.
It could be the anti theft system. Is there an in-line fuse in the wire harness going to the module?
If so, pull the fuse and see if it starts.
It could also be your main relay. It’s in the fuse box under the hood and is labeled “fuel inj”
Let me know what you find out 👍
Great video as usual. However it does seem a shame to be breaking such a straight looking car.
Yes, it looks like it just needs a bit of TLC !
I never wear my Rolex while working in tight spaces.
Great!
I have a 1990 Miata. Has power to the ignition but won't start. Suggestions?
Could be your starter motor.
Could also be an alarm issue.
Why did it blow is the next question. Question answered, thank you.
The 80A fuse usually blows when someone jump starts the car incorrectly.
@@MiataMan I have my Miata to jump cars a few times, never terminal to terminal, I always ground my negative to part of frame.
Is the engine sound a rod knock or lifter tick?
Lifter tick. Old dirty oil.
After an oil and filter change, it was a lot better. 👍
Hi Miata Man, I have a 97 w/a similar issue, wont start. However, dash lights and door buzzer come on. I changed the battery and fuse, still won't crank or start. Any suggestions? I appreciate the help. Thanks!
Try your starter mine was the starter fuse and the starter itself on my 94 I had no crank no start all electronics were working
so i had done this, replugged new 80a in and went to go reconnect the battery, battery sparked and blew the new fuse i just got, what do i do
The 80A fuse usually blows when something is connected backwards.
Jumper cables to the wrong terminal, etc. I would check for any non factory wiring and accessories that may be faulty or poorly wired.
I did what you did on my mark 2 only difference is that it’s a 100amp fuse. The new fuse blew as soon as I reconnected the battery. Any help please.
Have you recently added fog lights, stereo or other non factory accessories?
@@MiataMan no.
I disconnected my alternator and then reconnected the battery. I have ignition but no turnover and the fan is spinning. When I reconnected the alternator the main fuse popped and soon as I connected the battery. It appears that the alternator is the culprit.
I could use a new steering wheel xD
I got a miata with a dead battery doing the same thing. I was given jumper cables with her and I suspect that she's been jumped. I hear AGM batteries can't be jumped the normal way so whatever life the battery had was probably cut shorter. Just gotta go get another one
The small AGM batteries that are used in Miatas don’t last. They have a tendency to develop bad cells and die prematurely if not maintained. A conventional lead acid battery has more cold cranking amps, lasts longer and is cheaper.
The group size of the battery is 51RPS.
Note:
It’s always a good idea to check your battery periodically for leakage.
Leaks are rare, but can happen.
@@MiataMan Yea I hear that Optimas have been failing left and right since they moved to Mexico. I found a Napa with a rebranded 8AMU1R AGM roughly at the same price as the flooded near me. Was originally planning on ordering one off a miata site but everything starts out cheapish and then the tax and shipping fees kill ya. I figure if I can get anything over two years out of a battery these days it's cause for celebration.
I did all the above and still nothing I have no lights on the dash and I’m stumped on what the issue could be? Maybe bad wiring?
Check the battery terminals and the condition of the battery.
Also look for a bad ground.
Mine just decided to never start again one day and I just replaced that fuse but I still have no power off the key. Any other ideas?
Ingnition switch?
Faulty clutch switch?
@@MiataMan swapped that, starter, battery. I’m at a loss at this point
hi i put new battery on today still no power mine is 1999 mk2 1.8... I havent changed this fuse because it looks ok but I have no power.. my headlights dont come on nor does anything else
Does anything happen if you try to jumpstart it?
@@MiataMan no nothing at all no lights either but mine is mk2 so light wouldn’t flick up anyway, I think I see a tiny break at the 80A fuse upon looking closer with magnifying glass. So I’ve ordered one not sure why it would’ve popped tho I did leave the lights on I think to kill the battery initially but new battery on there now and nothing
@@MiataMan I tried to jump it 3x off my Fabia vrs which is a diesel so bigger battery to
Hey mine wont start, it cranks but no start, same year ?
Same problem. Got the alternator tested...wasn't the problem..checked the battery terminal wires..they look fine.... if I jump the battery it starts, but dies immediately if I don't rev it constantly
Is the starter relay and main relay different?
Yes. The Main Relay is labeled “Fuel Inj”
@@MiataMan where can I find the starter relay on my 91?
Wish me luck tomorrow I plan to check my fuse ❤😢
Yay it worked my fuse was blown and I replaced it. I’m cooking with gas . Thanks
Aye a C Package
If your Miata is an automatic, it won't come out of park with this fuse blown.
Good tip 👍
parts car? I'd resurrect it
Long complicated story, but it was not able to be registered.
