In this video I have a look at a 1994 Mazda Miata MX5 that was towed in as a crank no start. It doesn't take long to find the problem and order the part. -Enjoy!

Can a bad cas cause spark but no fuel? Im pulling my hair out. Lol
i like your hat!
Odd question, I've got a 96 miata, cranks but no start, it has spark and fuel, just replaced the CAS and it doesnt run now. The motor ran perfectly fine before being pulled. Everything is connected and bolted down. Any clue?
Can you show how to make or buy and what connection you connected the tester to the injector ? I'm assuming you didn't get a check engine light with a code for that sensor . If the check engine light didn't come on and give you a code what use is the sensor ? What would happen if you were driving and the sensor went bad ? Does the check engine come on before the car stops running so you have time to get off the road ? If the check engine light isn't going to come on and the car can stop with out warning what good is the sensor ? Why is it there ? Can you get rid of it and bypass it so your engine won't stop dead on the road and you get ran over because of a bad sensor ? A bad sensor shouldn't get you killed it should be their to save you by giving you a warning to get off the road .
Hey , guys I need help so it started to rain one night start the car it start fine. When woke up the next day I try to crank it wouldn’t starts when I check I was not getting any spark I replaced the coil and the spark plugs , I retime it, I replaced the cas , I replaced the ingniter I tried everything I’m only getting spark I two cylinder with the stock ecu I thought the ecu was bad I replace it with speedy efi now I’m not getting any spark at all. When I crank It with the stock ecu it makes that pop sound.If anyone has the same issue please inbox. I just don’t know what is wrong.
sound of him getting in & out of the mx5 is funny
Can u also do a voltage check on the signal wire with 12 volt supply. Using a regular meter?
i did a rebuild engine and i have this exact problem i get no spark but the engine turns the crank position sensor is good but not sure if the cas went bad
How did you know to go for the cam/crank sensor based off the info you had?
Quick weekend diag. Thanks Dr.O!
haha youtubes stupid closed captions said that you said
welcome to sylvan auto pairs
i had to watch that one twice
Your diagnostic videos should be organized and used in various college level courses, not just for auto mechanics.
Good video Eric O
Thanks for the video.
You broke rule no:1 Do Not move the seat.
Keep up the great video's.
The customer is wrong with his assumption. It is the new air fresher that's causing the non start condition.
just reminded me that the timing belt job i did on one of these 4 years ago, the guy never paid me lol
Great video, thx for sharing.
I am on vacation right now Eric in the middle of nowhere place called la grande Oregon I came out to my car yesterday morning to a no-start situation had to go through some of these procedures diagnose a bad distributor which by the way is brand new less than a thousand miles on it ordered one up now I'm waiting for it to arrive about 4 hours from now cuz like I said I'm in the middle of nowhere and nobody has a freaking distributor for a 99 Acura 2.3 l VTEC engine ridiculous there's another $100 for a hotel room
Dude, you need to invest in a lapel mic or something, 'cause damn!! Your audio quality sucks!
LOl a brake job broke the miata…haha..
Naw it’s definitely an “ever since you” my wife left me, my dog died ect ect 🤔
Nicely done!
Ever since you…….
Wait a minute….what light is that?
The battery is in the trunk
Thank you Eric. Good job. Have a blessed and safe week.
Why don't you use a timing light to check for spark? Seems like this would be a good way to isolate individual cylinder issues.
A 1994 Miata? Well. Everything is about to break, he knows that , right? Heck. A 1994 anything. I'm about broke everyday. Bones, muscles, wallet.
It's a "sinceya" problem… Did you move the seat??? Looking forward to the update…
Scope on the rope to the rescue. Back to basics again.
this has been a very good help to me and my mx5
Was there something that made you suspect the cam/crank sensor once you knew there was power to the injector, or is that just the standard order for troubleshooting these things?
Works on brakes, car don't run no more. Hmmmmm 😉
Great video, my mechanic hates the weekends too I'm sure you guys all do. He schedules me for Saturdays only. Shows me how dedicated he is lol, but I travel from PA to NJ and only go to him.
2 Part series you gotta love that!! Now on to part 2
Yer making it look too easy Mr. O.
Eric: Good morning! What can I do for you?
Customer: Ever since you worked on my car ________
Don't ya love them??
Thanks for the great editing. It really makes viewing a pleasure.
Those graphs seem to boggle my mind a bit, lol. Just not used to seeing them. Nice to know or at least hopefully able to refer to in case I ever come across this problem. Thanks for sharing.
Oh the quiet of working on weekends. No phone ringing, no one stopping by to shoot the well you know, or that guy driving by and honking.
I own one of these, I'm highly interested in this video, more so than most.
You holding out brake job videos on us? What the heck Eric!
Oh man, that Miata reminds me of an 87 Toyota Corolla GTS, a rear wheel drive four banger I used to own and really miss! Great basic troubleshooting and the timing light in part II brought back memories. Thank you sir!👍🏼
Ah, an engine that looks good without some stupid piece of plastic covering it!😬
A paperclip between TEN and GND in the diagnostic box probably would have shown that missing signal code.
I hate Vice-Grips, they can mar stuff up!
Did I hear a seat move?!?
Love these little cars,I have one and I’m 6.2! Lol!
