Your first statement is so true. I just fixed had a crank no start on a 1987 Jeep. The coil was suspect, but it passed all the resistance checks. That led me to thinking it was an ignition module but a new coil fixed the problem. You know the enjoyment of fixing a car with no new parts required. Lots of satisfaction right there. You are indeed blessed in many ways. Wow, adjusting the air gap was a huge difference in the signal. That was a cool comparison.

Great job Paul. You are amazing I will always watch your videos

[@SmittySmithsonite]

GREAT case study Paul, and excellent camera work and editing, Caleb! What a difference in amplitude with a tighter air gap! Off the scale! I do alot of small engine work, where the ignition coil is fired by a flywheel-mounted magnet - there needs to be a specific air gap (usually works within a small range) in order for the spark to be strong enough for the engine to start, run, and run under load. Was great seeing the difference a relatively small air gap change makes on the U-Scope there. Don't know why I never made the connection before, even after seeing countless videos on rust-jacked ABS sensors on GM products. I also thought a code 12 was "no codes" - guess that's GM only. Those "in-between" years where cars were computer controlled, but not OBD-II, were a pain in the ass! Both our '86 Grand Marquis and our '93 Volvo 940 are this way. The good thing is, neither one breaks down very often - they were very well built cars, as that Toyota was. Our Marquis is at 267k miles (thought it was a little less than that, but I just checked!), still on the original in-tank electric fuel pump, and distributor. But to be honest, I miss having just a carburetor and distributor, and a block-mounted fuel pump to deal with. I'll have one again one of these days! :) Thanks for sharing, Paul! 👍🍻

Hey Paul, great Video. I‘ ve learned a lot from your Channel. Here in Germany , I fixed a BMW X3 3.0i by using your Knowledge of Long and Short Therm Fuel trim. It had an Airleak caused by a smal cut in the plastic Valvecover between the Coils. Found by Smoketest with e- Cigarette and Pe Bottle blocking the Intake😬 Thought i was ready, but the Fueltrimm did not get under 10% on both Banks so check engine stayed on. Then we change the MAF and the Car was healed after beeing 8 weeks in a Mastershop🙈 Took me about 4 Hours. There are too much Partschanger in the Shops today, without Laptop they are nothing.

ScannerDanner keeps filling my 'air gap' with knowledge. Like a pitbull terrier - he never gives up the fight.

[@xerxes456]

Great video guys it was a really well explained video how the system works. I like the distributor system that has everything like ignitor and ignition coil on the outside I have noticed that you will have a better secondary waveform on that system when you put the scope of the king lead and much easier to work on. The STA signal is used by the ECU to allow additional air to enter the intake manifold while cranking the engine. Additionally, it is used to determine when to enrich injection for starting and when to operate the Fuel Pressure-Up (FPU) system. In the event that the STA signal malfunctions, the engine may be difficult to start. The STA signal at the ECU will be low at all times except while the engine is cranking. While cranking, the STA signal goes high (cranking voltage) as current flows through the closed ignition switch and neutral start switch contacts. This is what I found on the STA signal Toyota has a lot of abbreviations.

[@ScannerDanner]

The STA signal is involved with the starter circuit. That much I knew, but for them to describe it the way they did in that flow chart was super misleading and incredibly stupid :-)

[@larrying6909]

Dude, great stuff... However you are incorrect about that capacitor on the inside. That inside capacitor being NG is exactly the reason you can see that ignition spike on the VR signal. It is the function of that capacitor to eliminate that ringing (read spike) from the primary of the ignition coil getting into the rest of things nearby. BUT also remember that same ringing spike getting into things is also picked up by the VR coil (oodles of windings to sense it) and that was what you were seeing. Some might argue that the capacitor is used to produce the spark like in the old Kettering ignition systems with points and condensor (capacitor). NOT here. It is merely the filter keeping that noise out of the rest of the system arresting it at its source. I should mention that I am a mechanic like yourself for the last 47 years and an electrical engineer for the last 27 or so years. Also, I have been designing ECUs and other stuff like this.

Hello Scanner Danner, I love your videos and I have learned so much by watching them. Long ago (40 years ago) in High School auto shop I was Blessed with the teaching of an old school auto Mechanic Named Bob Van Den Brink (Mr V as we called him) and for a wonderful two and a half years he taught us about fixing cars and about life. I miss those good old days and see your videos brings back those old memories when cars were fun to work on and hanging out in the shop was a favorite past time. When I see your videos with your students I can see that they too have their automotive Jedi Master and they are in good hands and will become true Automotive technicians who fully understand a car from the ground up, and will not become trouble code chasing Parts Changers that are far too common these days. God Bless you Paul and thank you so much for your teaching and for caring about not only the mechanics (automotive or otherwise) and for the customers that rely on people like you to get them out of trouble. Just a quick question, in this video you recommend this Uscope as an affordable scope to use and I was wondering if you could post a list of scopes for those of us that are not auto mechanics for a living but need to work on cars and want good tools to work with. I am a maintenance mechanic that works on industrial production machines and cannot afford the $5,000 Plus scopes but would like a scope in the $1,000 dollar range that will give good displays for square waves, voltages and some of the other features that you show in your videos. Could you post a list of scopes from $400 to $1,500 range that you would use and recommend? That would be a big help to all of us. Take care Paul and thanks again (and of course Caleb too for the outstanding video and the long hours of editing) so that you can bring learning and light to a confusing craft. Ross Hurt [e-mail]

No wonder I couldn't find this video when I had (and still have) a misfire with my '95 Corolla. I was looking for OBD 1, instead of "pre OBD 2", and just happened upon the part 1 of this video. I've had the misfire since around 2015, but part of the solution was to turn the AC on and put it in neutral at stop lights. If I pushed the car too hard on onramps, it would hesitate also. I found a guy selling a distributor and bought it. His distributor had copper windings coming out of the pickup? like yours. But I swapped what parts I could and still had an ignition miss. But at least I know I was on the right track. Because I did do cap/rotor/plugs/wires and still had/have the same problem. I did EVERYTHING under the sun away from the ignition system to find the problem...no dice. Will be replacing the distributor assembly because this one does leak oil past the seal, and the rotor/shaft is welded on both ends, so I can't replace the seal.

[@ScannerDanner]

Is it a constant misfire? If it is, step 1 is to do a cylinder drop test and once you know which one it is, then compression and injector needs tested on that cylinder

always great videos Scanner Danner,, thought I would let you all know these coils do fail, they usually leak secondary voltage to ground, you will usually see the white gray tacking. you might have to remove coil for inspection.. Pick up coils also fail in many cases you will have to get it hot,, as a trick we use in the shop, heat the distributor with a heat gun or hair dryer being careful of course. when the ignition fails while running, then you can measure the resistance across the terminals.. I believe the max value is 180 ohms.. 25 year master diagnostic tech. japanwest, regards

That purely for the content is probably one of the best videos you have done Paul. That for any regular mechanic or Diyer could have been a parts cannon blitz. Plugs leads cap rotor coil, screw it complete new dizzy. Or the lucky mechanic, it needs a dizzy. Correct but what was the real issue? This project had multiple issues. Swapping of known bad distributor for a possibly ok one. Swapping parts of unknown condition all lead to an extended repair time. Testing of input signals was the key to the replacement dizzys correct diagnosis and no parts repair.

Thanks for timing tip. I was unsure, do you change timing while paperclip is installed Te1 + E1. I somewhere read that without paperclip, computer automatically try fixing timing by itself.

Nice! Scanner "Ivan" Danner!!!!

heres a thought for you paul- since the ignition trigger is metally connected to the cam trigger through the shaft it is possible for the ignition to be transferred up the metal by indictance and picked up by the pick up coil. i'd be willing to bet under the plastic on that ignition coil is a shield wrapped around and grounded through a mount screw. probably the reason it stunk is the signal was so low that top trigger is so the computer knows #1 tdc for sync on injector pulsing. the bottom runs the coil and it just fires every 90 degrees of distributor rotation or 180 crank. the keyed rotor is what times the cylinder. so the injectors were firing out of time.

Surprised you didn't just use your scope to set timing. Although showing what we had back in the day is probably best for those that have never used a timing light. AESWAVE Lead kit would also work well to jumper if folks don't want to use a paperclip. Nice that you are able to see the marks so clearly. Old GM'S and Fords were always covered in dirt. That hat was hilarious.

Robinson's Auto Diagnostics , how would you use a scope to set timing?

[@kevincampbell8298]

Yes signal getting over ridden with noise. If there were no adjustment I would have been tempted to slot out the hold down holes. Especially if you aren’t keeping it. Crazy how the one that was in there shredded the coil of wire!!!

FRAME 21:29! I know EXACTLY what your saying, I’m cutting my teeth on my 1986 EEC-IV… I have the old snap-on brick scanner that can’t even communicate with the ECM, as you mentioned in one of your EEC-IV videos “show me some perimeters and let me be done with it! 🥶”

Just got our asses kicked by a 86 Mustang 5.0! I don't want to spill the beans, but this comment isn't going to be seen by most, so I'll tell you. We got 3 bad ignition modules right out of the box! 4th one fixed it. Video coming soon. Don't say anything :-) Hope that helps you?

Danner I hope you read this , I want to sincerely thank you for educating me over the years. Ive watched every single video you have and learn a lot. Today I applied the knowledge on my out of warranty 2015 BMW 3 series. I got a check engine light and so I first invested in an Autel MK808. Scanned the car and found our it had something to do with the front left shock. ( I has an electronically damened shock absorber ) I graphed left and right side sensor amperage and found out that the leftside was being overcompensated driving over uneven roads. So I was kind of wondering if the shock itself was bad on the left side or what. I couldnt make up my mind then I looked at the reference voltage , they both showed 5v on the money. but then I noticed something , the left side raw voltage was showing 2.3v instead of 2.5v which it was on the right side. Kind of odd I thought. It was getting late and I didnt want to get out the tools so I just turne the steering wheel all the way to the left and put my hand on the sensor mounted on the side of the shock and wiggled on the cable while lookingat the graphed sensor voltage. the raw voltage made all sort of up and down shapes and DING , the check engine light came on. And so did the bulb on my head :) Thanks to the persistence and tricks I learned from you my car is not going to the shop and is not going to be shotgunned with unneccesary parts. Thank you.
