Paul your tenacity is what makes your videos so appealing to me. I'm on a quest to watch all your utube videos. Soon, the premier channel follows for me. WHY? Because in the work-a-day world of changing tires and doing brake jobs and oil changes and all those other tasks we do as techs, many of us hunger to be really good at diagnostics, but don't get enough opportunities. I have learned so much from all your videos. I look forward to the new ones coming out and re-watch older ones often. You drill the principles you teach into peoples minds and that is a good thing.....The test light, the 5 volt ref, tach movement, cranking sound, prove your ground, idle fuel trims/possible vacuum leaks and on and on. A wealth of knowledge and skill, derived from a whole lot of hard work, over many years, coupled with a great desire to teach and share it all, must Always be celebrated. Oh, wait, it is. 323k subscribers hit that button for a reason. Paul, thank you for doing what you do. It has helped me achieve a better understanding about a subject I find fascinating.

[@Ulrich_Wolf]

Small shop owner checking in here. You bring up that the parts store should pay for lost time. I agree, and I have 3 different scenarios to share. 1. My personal 2002 Ford Mustang GT. PCM went. No problem, got a Cardone reman, car starts up, we figured it was fine. 30 days later, the car intermittently would crank no start, setting U codes and flashing the Theft light. After checking CCRM, powers, grounds, doing a pinpoint test on the SCP network, everything passed. So, we called a PCM. Warrantied it out. 30 days later, the replacement does the same thing. Same symptoms, same 2 hours of diag and pinpoint tests, same results. Warranty a PCM. Third PCM - runs 30 days. SAME symptoms. This time, I tried something off the wall. Bought a used OEM PCM from Ebay, flashed it, programmed keys, and the car has run fine for 3 months now and never missed a beat. 2. 2013 Chevrolet Cruze 1.8L. Came in, had a ripped PCV diaphragm, needed a valve cover. Installed a parts store valve cover, the car didn't make it home to my customer's house! The PCV in that one let go so violently that the intake filled with engine oil. I had to pull the intake, completely clean it out, and then replace the valve cover again. This time, a GM part went on. No more trouble since! 3. 2010 GMC Yukon Denali. Reduced Engine power concern. Diagnosed a bad TPS. Put a TPS on it, it lived 24 hours. Got it back, tested, sure enough, bad part. Got a warranty replacement, installed it, and it was worse than the bad one! Went to a different vendor, and that one has been working well. Between the Mustang, the Cruze, and the Denali, that was probably 20 hours combined of diagnostic and repair time. Who didn't get paid for that? This guy.

[@ScannerDanner]

This is exactly what we are all seeing! Pinning this comment! If we can start really making some noise and raising awareness, maybe things will change? Hope so

[@Mac-mu9cs]

I bug my boss all the time to do warranty claims . I dont know why he does not

[@Ulrich_Wolf]

@@Mac-mu9cs - I'll tell you why. I have a labor claim open on the Cruze still since OCTOBER! First one I ever filed, and it will likely be the last. I provided all the info they could ever ask for, and they simply don't want to deal with it. It's hanging in this odd area of not approved, not denied......just....hanging out.

[@lance1097]

@ScannerDanner I rebuild transmissions, and aftermarket parts cause comebacks. Used oem or new oem is the best way to go. I wouldn't hold my breath on the aftermarket raising their quality. People continue to buy Their products to save money, and it costs them more in the long run.

[@Ulrich_Wolf]

@@lance1097 I agree with you, but a majority of the cars I get in are older. There's typically not a lot of availability on dealer parts for older cars. So, a lot of times, I get stuck like Chuck.

[@kevin_nagle]

Coming from someone who has been playing with Foxbody Mustangs since the late 90s I can tell you I realized early on that any parts store module was junk. We even had trouble with the MSD, Accel & other aftermarket ignition companies modules. The only module that I can say always worked everytime was the Motorcraft module. Although now we are using aftermarket EFI with crank triggers, cam sync's & MSD dual sync distributors, every so often we have an original or modified Fox still using the factory EECIV, I'm lucky enough to have Down's Ford close by & they still have stock of the Motorcrafts modules. This was an excellent series, thank you for still doing the older stuff including the Foxbody & other EEC-IV stuff because I still work on that stuff in 2022!

[@ScannerDanner]

Now you know what to look for instead of swapping parts 😉 In all honesty, as I said in the video, swapping parts would have been better than what I did. We knew where the problem was, I just wanted to prove the exact area. Hope it helps some of the EEC-IV people out there

[@scientist100]

I've wondered if other shops were having this issue. As a troubleshooter and seasoned diagnostician, there are cars that are not easy due to the complexity and possibilities of the issue at hand.

[@Jpilgrim30]

@@scientist100 that and the parts issue he’s facing here. I’ve never seen as many defective parts out of the box that I have the last few years. PCM’s, alternators, power steering pumps, glow plug modules, etc. Doesn’t matter how complex or simple the part is the quality has went to 💩. It’s about to the point where if you want to get a part that’s likely to work you have to go OEM. Just the ones off of the top of my head I put SIX power steering pumps on an accord before we got one that worked and was quiet. Four glow plug modules on an F-350 before we got a good one. Three rack and pinions on a 2012 Camaro. It will just about drive you mad. Thankfully that accord power steering pump is easy to change or I may have ended up lighting a match if you know what I mean. They also need to test these electronic parts especially the remans better. I’ve been running into multiple bad Reman ECMs on fords and Chryslers. They usually get rid of the initial problem but have something like a bad purge solenoid driver or something causing you to have to do it all again. Kind of like Dorman and how they want to make a million junk parts instead of fewer quality parts.

I finally ordered a kit to relocate the TFI module off of the distributor. It came with wires and a heat sink. I relocated the TFI module to the driver side strut post and it solved the problem. The distributor gets hot and heat sinking an electronic circuit to an already hot surface was a bad design. Thank you for all the videos and the wealth of knowledge you have shared over the years.

[@lontgom]

I also wanna second the fact of new parts being bad, I can’t lie; it’s relieving to know that I’m not only one who bought multiple modules and had the same issue. These ford ignition systems make you feel insane, because you do the same thing more than 3 times and end up with the same result; only to change it one more time for it to work properly. I’m not joking when I say I purchased 4 of these modules, an absolute joke of an ignition system; they all did the same thing. To this day i have not found one that works properly, and I’ve tried from 4 separate dealers. It’s only this video that guarantees what my problem is I have checked the connector as well. Seriously thank you so much for making me feel like I’m not insane. Even finding the black module was a pain all on its own, I called Ford, MSD, Holley, autozone,Napa, oreilly’s, Rocksuto, and nobody could give me any information as to what the difference was between the two. I believe they touched on it in the previous video, but there is a MASSIVE difference in the two modules; if you have the incorrect one the vehicle WILL NOT START. It will not send spark to the Dizzy, for anyone who needs the ICCD Black module, the only ones I’ve seen that actually send a black one is TRANSPO by WAI GLOBAL and they go under the model name of FM515. Most of these dealers just think there’s no difference and act like your dumb for asking specifically for the black one, there is a difference and your motor will not start without the correct one. Sorry for the long winded comment, but I just wanted to spare anyone else the absolute journey and pain it was to find solid info. Thank you again for your persistent effort to teach us this stuff, I have a feeling we’re gunna need to know these details for the future ahead of Im honest. In closing, no it’s probably not your fuel system, it’s probably not your intake or any sensors , it’s not even your spark delivery; it’s just that dumb asinine piece of Ford history called the TFI MODULE😂(ignition module)

[@richardostrowski6420]

Back in the day, we came upon this exact problem on Ford motors. First, they make a TFI test kit that checks the module, pickup and coil and takes all of 15 minutes to check. That being said, we dealt with stuck distributors on these motors also. What we found was that the oil pump shaft drive that is driven by the distributor would seize to the distributor shaft itself. We would have to remove the oil pan and pull out the oil pump assembly to get the shaft out. With the pump/shaft out, the distributor came right out. There is also a clip on the shaft that keeps the shaft from pulling out of the oil pump when removing the distributor.

I greatly appreciate the guts of the module being shown! That’s the first thing I would have done after discovering they are junk. Unfortunately from that angle on my TV, I couldn’t see much. I would suspect that the terminals have some super thin wires going down to the board and one has broken loose. It would be interesting to see if soldering on new wires from the terminals to the board would fix it.

[@ScannerDanner]

It would have been, but I wasn't interested enough at this point in this case study. I felt defeated at so many points in this one. Once it was fixed, I didn't care why or what part of the p.o.s. ICM was bad, or made incorrectly. I only cared about knowing that it was bad. In hindsight, now that its been a month or so, that would have been cool to experiment a bit 😉

[@dharley189]

We only got to see two hours of your frustration. I’ve been there so many times. Last few years defective new parts became normal for all brands. Before TFI we diagnosed the modules in late 70’s cars by pouring a gallon of water on it to cool them. If it started then it was replaced. I really enjoy videos since retirement. Wished you were around decades ago. Aggravation was just as bad. 👍 for granddaughter to fully recover.

[@techguy5601]

It is a circuit layout design issue, the high current lines that run the ignition coil trace is ran under neath all of the sensitive digital data lines impedance matching resistors, because the supplier did not pay for a multilayer board to isolate conducted emissions. This would cause loop back with the output causing random signals depending on frequency of pulses. In electronics we call these oscillations. Inductive load like ignition coils need damped with a voltage limiting diode. Also, I hope your granddaughter is doing well. Prayers for her recovery.

[@danielmusat597]

Hi Paul, Nice outcome. I wouldn't have suspected a fourth module to be bad but... reality is what it is. I noticed something in your behavior and I should let you know cause it's counterproductive: when you are about to catch the culprit you get overexcited and begin to omit details and make mistakes. And, of course, you get frustrated realizing the mistakes that you did and lose control over the repairing and also lose focus. You should go till the end with a supposition and get excited at the end only. Cheers!

[@ScannerDanner]

Bad new parts definitely make one second guess things, even to the point of making mistakes in one's thought processes. I too, when I watched this said to myself a few times, that what I was chasing was not a possible issue. Like the pip wire dropping out, I proved so many times that, that was not the case, yet still felt the need to check it directly. It wasn't that I didn't finish a thought, it was me searching for the answer when I believed the module to be good. No way 3 modules are doing the exact same thing! But it was.

[@danielmusat597]

@@ScannerDanner A module sitting on an engine part that gets very hot and very cold should exceed some standards. Looking at the image at the end of the video I see a crappy solder joint in the upper left corner of the module. A connection that seems to go from the switch side of the power transistor to the outside of the module. That kind of thing is certainly a culprit. At least the connections from the board to the outside world should be welded for this kind of module. These modules should be mounted away from the engine in order to work for some time. Maybe that's why they seemed to work in the beginning but failed afterwards. If you still have access to the car it would be interesting to re-solder that joint and check the functionality of the module. All in all this is not a AEQ-100 or 200 module. It is just chinese junk...

Paul and Caleb, hope your granddaughter/daughter is back home and doing well! Aftermarket parts can be so frustrating, wouldn't be the last time we are going to run into this kind of concers with parts. Thanks as always.

Those are just surface marks from where the wire above it was soldered to the tab.

[@computerroger]

I think the more major problem is the blob of solder above the "0599"(maybe 6650) resistor that is over the transistor, resistor and a capacitor. That could cause an issue or two.

Paul,I’m a retired 35 year aircraft technician who started out in automotive mostly on mid seventies vw bosch fuel injection cars which was the beginning of todays systems .I have a large shop on my property and love troubleshooting. Today’s cars are about as complicated as some aircraft systems which is very interesting to me. I am in the mid stages of multiple sclerosis so I am much slower nowadays. I am a new follower and absolutely love your videos and own a copy of your book. I watched the video on the 80’s mustang and not sure if you have ever heard of Deoxit contact cleaner . It causes a good contact on electrical connections as I used it on autopilot problem connections. Give it a try sometime. Thanks again for your interesting videos.your knowledge shows.

[@chevboy4.813]

Bad solder connection on the board from the pin tab. Lead free solder used on everything these days. I just went through this on my damn clothes dryer! A $180.00 board assembled with lead free solder of course. I found 3 "witch hat" broken solder connections. On what part you ask? The main rotary selector switch. A true bane in the electronics world for techs!!!

[@RichardSandstrom1163]

As an old school tech still in the field and working on today's modern vehicles I admire your dedication to find the issue instead of swapping parts! I remember the EEC-IV and CCC systems in my early days and the hair I have lost over those terrible designs. Made me feel good seeing someone else going through the same. I will say that I have learned so much by being in the field from the beginning and sticking to the basic fundamentals with a lot of my work. today's vehicles may provide us alot of data to look at to help pinpoint an issue, but it always seems to go back to the basics when finding a problem. Great work you do and have been following you for a long time. I may have to swing by sometime when you are at Danners I have a shop on the other side of South Park.

Any time you get to repair something that was touched by others before you, there enters a whole new set of circumstances and along comes all the unusual problems. Even simple questions become difficult to answer and you begin to second guess yourself. Ive been there many times. The difference is you guys persisted and came out on top and i commend you for that!!! Only time and experience will get you through that and you will be that much better for the "next one". I never could understand why the auto mechanic always gets stuck eating the labor from bad parts??

For the masses - Highly recommend using OE for all replacement electrical parts. Second choice - use non chinese replacements, hopefully from same source that makes OE. If I have to use a non OE component, I'm always wondering when intermittent issues pop up. I guess a Motorcraft DY1284 was not available?

Here in Australia we have the same problem with the ford aftermarket distributors gears, you have to swap the original gear from the genuine dizzy. I put one in a vehicle before we knew about it, and it stripped the cam gear. Typical of aftermarket junk, they spent all the money on the metallurgy of the gear (hard as woodpecker lips) and none on cutting the gear at the correct angle! Love ya work Danner brothers.

Totally Amazed by your knowledge on all circuit and signal.You got a lot of patience i think i would take a sledgehammered after a lot of frustrating stuff like that.I have been through bad parts as well and when you could buy the original parts there s almost no point to buy parts from other brands.Like spark plug when you have a motor built with a brand of spsrk plug it is hard to have a better spark plug then original brand other than champion.Really Bad experienced with Champion lol.Water pump original 120000km .Parts seller 50000km.You are an Excellent technician and also an awesome teacher.

To your credit, you were right on the problem and stayed right on top of it. Many people (me) would start jumping all over the place after a while.

[@ScannerDanner]

The real key was in understanding the circuit design and that when the spout is unplugged the ECM has ZERO control, or influence on coil control. So I knew from the start that I was dealing with an ICM, PIP, or wiring issue. But it was still super frustrating

[@richjones8696]

I have owned several foxbodys over the years, all of the aftermarket modules on the EEC IV are garbage. First thing I do is install an older analog MSD 6AL (newer digital boxes are junk like the modules) then remove the “salt and pepper shakers” and solder the harness directly. I had my suspicions that it was a module issue just from my personal experience but I like many technicians hate shotgunning parts. Thank you SD for confirming my suspicions, great job guys!

[@randy1ization]

retired HVAC man here, I can tell you things that would blow your mind that I went thru in my career. I was the guy they would call when nobody could figure the problem out. not bragging, I learned hvac at a young age and retained alot of the knowledge. then I worked for several different companies. got alot of trained thru Sears and no bucks, and learned alot from senior techs before I started my own business. if u would like to hear some crazy problems pm me, or if you have a problem u need help with just ask. I kind of miss the challenge.

[@randy1ization]

I was an hvac contractor and appliance tech.. a very strong electrical understanding will get you thru complicated problems., and always remember in order to figure out what is wrong, you must understand how something is supposed to work in the first place. I worked with a tech that had no clue how most things worked in an hvac system.. what he did was memorize what parts fixed what problems when he was a helper. he got abt half of his repairs right.

[@secondwindmusicproductions]

It would not help this problem but there is a good contact cleaner spray. It is called DeoxIT D5 and it is used by electronic technicians for audio connectors and computer connections frequently.

[@russellstephan6844]

I'm just an intense DIY'er. Last Summer, my 1993 C1500 was running rough with an ignition control module error stored in the ECM. I did call the local parts store to make sure they had an ignition control module tester rig. They did. The module tested bad. I had them test the one I was buying to make sure it was good out of the box. A long while back, my lawn mower (Deere with a Kawasaki engine) had a seriously bizarre surging issue. I cleaned the carb a dozen times. Spark looked okay. Finally, I sweet talked a neighbor down the street to loan me his Deere for parts substitution. When his coil assembly was fitted to my mower, it ran perfectly. Well, there we have it! A new coil and I was back in business. Sometimes, that rabbit hole is long and deep.

[@xpertNetwork]

Don't trust part stores unless you know someone or watch them hook it up right and see the screen.

[@marinkojezabek2555]

That was epic Paul and just shows how complicated these older systems truly were back in the day. These systems still come back to haunt techs now and I was engrossed by you and your brother trying to figure out how these modules truly operate. It does not make sense to me that disconnecting the spout wire proves a pick-up coil can be faulty when the pick-up coil is used as a signal for the module anyway in module mode. If the pick-up coil is faulty then surely the car will miss / not run correctly always, with or without spout. There has to be someone out there who understands these systems like the back of their hand, like a Ford tech who actually did factory approved dealership training on these systems and who can reveal more info. The GM systems were similar but did not seem to cause as many headaches as the Ford systems from what I have been told.

I commented on the 1st. video, I never considered where the Parts came from. In hind sight, I wish I would have thought of it. We have a local guy that we call in when we can not figure out an issue. He is a lot like you but he uses all Factory Equipment. He gets the Bingo answer 98% of the time. He is also a Teacher of Carquest for the Local Shops around my area. One thing he has always stated: "DO NOT USE CARQUEST REMAN DISTRIBUTOR UNITS!!!" "Most of their Ignition parts are junk." I feel for you. You seemed to have hit a wall and went too far trying to figure it out. Just like you said, it was a good runner until the no start, Distributor was the only change for the current issue. That could have eliminated the Plug. I appreciate the extra effort you put into it. Now one has to wonder why the Distributor will not pull out... Did the other shop install it without any Lubrication on the Gear? The Rotor turns as it lifts a little, the Gear seems to have some slop, maybe Mushrooming?? Oil Pump Drive hammered in???? Does not really matter at this point..
