2006 Ford Ranger 3.0L Missfire Diag - Bad Pcm after 2 shops I figured it out

[@bobimbordino3024]

Your knowledge is amazing. You’re the only person I trust and I’m blessed to know. Thank you for all what you know

[@kwheeler61692]

Great video man, with electrical, a proper diag is so crucial. Theres too many people who just throw parts at it hoping to fix it.

[@farmark457]

Great logical step by step diagnosis. Electrical can be intimidating but easy with the right method. Thx

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 .

[@jasonchristopher2977]

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.

Your comment is so goofy This can literally be with any manufacturer Get over yourself

[@johnphillips222]

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.

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.

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]

Bolt the filter back up?

[@040mobil]

@@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 !

[@merrillschaps2325]

@@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]

@@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.

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

[@FordBossMe]

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

[@michaelchan8915]

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

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

[@GuretoSefirosu]

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.

[@Brylini]

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...

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

@@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.

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.
