If you were at Nav corporate, using the logic probe would get you fired. The mismanagers in charge had never heard of a logic probe before and did not understand how to use a logic probe, super simple. It was so sad to see such fools in charge of service documentation. They were pretty dumb and arrogant at the same time. I completely agree with how you dignosed that. You would get an A+ from me and a failing grade from the alcoholic managers. They stopped learning in the 70's.
Ironic that just last month I had a #3 cylinder misfire on my 09 Taurus X . I swapped the plug and coil pack from cylinder 3 and 4 . If the coil or plug was bad , my code would have changed to the next cylinder . It didn't . So next I used my multimeter to check continuity between the coil and pcm pin 12 on the wiring harness which was fine . So that tells me there is no coil driver output from the PCM . Installed new PCM . Problem fixed . Simple basic procedure . I'm surprised two other shops couldn't figure that out before they brought it to you . Great video as always .
Why I trust him and ppl like you who actually do the work. Not just say you need new plugs, coils, and if that don't work maybe a pcm or wiring, all the while charging $60+ hr and maybe the issue is fixed. If more mechanics would chase successful work as much as money, this would be a better place for customers.

Electrical diag can be tedious. Knowledge, experience, and patience are essential. I liked electrical diag, it just took years of doing it to become proficient, strong work Boss.
Got an EEC-V computer, failures got more common when Ford started to .mounted them with the connector outside the cabin. The EEC-IV were even worse, they don't want to be outside like the newer Motorola PCM. When a Ford PCM fails, the driver relays stick to ground. Used to have the fuel pump relay stuck ON, or a fuel injector would stick and fill a cylinder. When something is stuck grounded out, the PCM is suspicious or the PCM Relay.
That was an AMAZING diagnosis Sir!!! You know, in my thirty years of doing this for a living, the one thing I'm always nervous about, to this day is when diagnosis leads to a module replacement. Almost every time when that is the next step, I question myself over and over again, did I miss or overlook any other steps? And we're not talking about FICMs on 6.0L diesels that almost every one of them would need replacing at some point. Those CMP sensors and synchronizers used to wear out on those 3.0L too. I replaced a lot of those on the Taurus from the early to mid 2000s with that same engine. BTW, where did you get that fancy Dancy tool of yours? I think I'm going to need to score one for myself, along with a decent jumper wire set.
It's just a power broker but Ansel makes a Power Probe as well that does the same thing for half the price .... not even, actually a third of the price
You could have a clogged catalytic converter or something wrong with the exhaust system is restricting it from breathing that has the same symptoms as not getting enough fuel
You're awesome! Great job! You maybe getting more customers coming to your dealership as I have been recommending Dundee Ford in East Dundee. I also have a quick question Rich nobody has been able to help me with. The transmission filter won't stay in the transmission. Twice now on my '07 Town Car I have done a fluid and filter change and both times the transmission filter was laying in the bottom of the pan with the seal still on the filter. I only purchase Motorcraft transmission filters. Do you know what causes this or if Ford is having any problems with the transmission filters?
@@FordBossMe maybe he forgot to take the old filter o ring out of the hole. That would keep the filter from seating properly. Just a guess. Great content this week !
@@FordBossMe there isn't a bolt. The seal on the filter holds it into the transmission. I wish these filters were bolted in. I'm thinking the seals are failing to hold the filter in.
@@merrillschaps2325 I wasn't sure if maybe yours was made with a bold or maybe some kind of Ridge to hold it up I don't remember what mine look like when I went in there but I do know that you have to remember to pull the old old ring out of the whole I'm not saying you forgot but did you make sure that there's not the old seal up above where the filter goes in
@@FordBossMe No, I made sure the old seal was out of the transmission and I pushed the new filter in until it was flush with the valve body. I never had this problem with my '01 Ford Crown Vic P71. Just curious if you had any ideas. I do really appreciate your response and knowledge Rich and that goes for others on this channel as well. This is the best channel to get good honest car knowledge. Keep up the great work!!
Im having the same problem with my 1998 ford ranger 2.5 it has a misfire on #4 and its shifting strange and itll go into a stall were can i get a good pcm at
Hey Rich, hope you’re doing great this Monday morning. I’m just gonna get to the point of my comment. This past Friday, my Pops purchased a 2017 Transit 250 with 77k miles on it. I want to do the transmission service of drop and fill on it with the filter change. Is it possible to drop the transmission pan to do the job, or does the subframe get in the way? And if so, how many quarts of transmission fluid would I need to do the simple drop and fill? Hope to hear from you, and thank you for your honest input on the videos that you post 🤙🏽🤙🏽
I don't know off the top of my head I got to look it up Give me some time man everybody wants something on here and I don't remember to do everything for everybody because it gets overwhelming so you may have to end up remind me later today
Okay so you do have to remove the subframe to get the transmission pan down and it is a mother and the fluid that you're going to need for a basic service is about 5 to 6 quarts of Mercon LV
I wonder could that be the issue with my 2017 Explorer xlt. New spark plugs , coil pack and fuel injectors and still getting misfire on cylinder 1 and 5.
I have a 98 Ranger 2.5L,one day I started on the morning and fine,later that that I started,go for a Drive and it shut off,the fuel pump is not activating,relay,fuse and inertia is good.I bypass the relay and the fuel pump kicks in but it doent start,I dont have injector pulse neither.I might think is the pcm.What would you think?
And I know some of them need to see the crankshaft position sensor working correctly or it will not let the injectors Fire or the ignition coils so make sure you got a good drink sensor on that thing are you saying the RPM gauge register RPM on Startup while you're cranking it over or is it buried and not moving while you're cranking
I changed my ignition coil, wires, spark plug, still got P0302 (cylinder 2 misfire) on ford ranger. Took to a shop and they switched around the fuel injector and put a new spark plug still came up with P0302 miss fire, and told me they don't know what's wrong with it...
Okay did you do what I told you to do in this video? Because in this video if I would have been in an experienced person I would have done the same thing and not knowing what to check but in this video I show you what to check
I had a 1995 Dakota Club Cab 5.2L 4x4 SLT once. In 2006 the thing started misfiring, running a few minutes and dying, not restarting, and acting just insane. I checked for codes with my OBD2 tool. No codes. This made no sense, so on a hunch, using the last $600 I had at the time (was in college getting a second degree) I purchased a new PCM. When it arrived I swapped it in (I had to give the company my VIN and other info) and she ran like she was new. In 2006 or 2007 it died again. Apparently, the PCM in 1995 and 1996 Dakotas was prone to failing every ten or so years.
Had a similar problem with my Crown Vic.....cylinder 1 and 5 misfiring when engine at low idle.....as at a stoplight. After about 20 seconds at stop, in drive, with foot on the brake, the engine misfired and died. Finally got another ECM.....voila...problem solved. Would have been nice to do that BEFORE I ripped out so much of my hair.....lol
Did you not pay attention to the equipment I was using I can't belive I'm even explaining this The pin in the pcm connector was an actual pcm pin so better than a flex probe The light was the end it.naturally came with so I didn't need anything special to test the circuit Can we just say thanks instead of questionnaire all the time That would be awesome lol
I have a question for you, What's your take on this Tribotex nano particle nasa snake oil that's supposed to fix wear in engine, trans, diff etc? You ever hear about or know about this stuff? Supposed to be real deal. Idk. I'd rather ask someone who knows like you then spend 100 bucks on a syringe full of promise. Thank you.
@@FordBossMe I'm like you, only way to fix worn bearings is a teardown and replace them. But after trying Turtle wax hybrid solutions over months and months of washing and it's performance, if the nano tech is anything like tribotex, maybe possible? Idk about you but ceramic and graphene type coatings work very very well. I'm not certified in mechanics, went to school and have done them in some form in last 25 years. I've tried alot of Snake oils. The only thing that has really worked is Marvelous Mystery oil, and the cans of oil, trans and diff additives like you use. Had success with head gasket sealers, but always eventually fail in long run. Idk. It's $100 for a kids size tylenol syringe full. Thank you for your time. I rely on your wisdom and knowledge. I know alot of good mechanics, only a few great mechanics, you being one of those. Keep up great work.
@@FordBossMe ok one day check engine stop coming win I turn key to start it den next win auto zone to it scan nothing reading iz PCM or ecm going bad it's 2003 2.3 ranger
World Ranger [all countries non usa ] in 2006 to 2011 was a PJ or PK 2.5/3.0ltr direct injection Turbo diesel . Mazda UN model. Available Africa / Europe /Asia/Pacific /South America . Prior was 4cyl 2.5lt diesel and 4.o v6 ltr gas and some 4cyl 2.6 ltr gas . Only a few parts would interchange with the USA models . Prior to 2006 called Ford Courier or Ranger or Mazda B series pending on country . All these were NON usa versions. Very confusing model line up
Lousy environmentally friendly solder that’s used in the circuit boards that doesn’t have the expansion and contraction characteristics of good old lead based solder and that leads to cracked solder joints.
