Thank you again Wess. It's kinda hard to watch you trouble shoot these diesel engines. Our Son was a diesel technician working on fuel trucks. He also was going to school and aided the instructors and helped other students. He passed away in June 2019. He would have really loved your channel. Have a wonderful day you are truly blessed.

As a mid-90s ambulance owner... These things are complete wiring nightmares. The amount of auxillary wiring in the dash is INSANE. I pray you find a mechanical issue and don't have to start digging too deep in the elec

[@MrAcutecareems]

They are overwhelming sometimes. But you just have to separate the conversion wiring from the OEM. Then it is not that bad.

[@michaelchan8915]

Ford dealership technician here. There was a technical service bulletin released way back, about a water shield installation to protect the IDM from water ingestion due to where they are situated on these vans. This was why the Ford diesel class instructor I had at the time liked to refer to 7.3 IDMs as "water traps" and 6.0 EGR valves as "carbon traps". Usually high ICP like what you were getting would be a result of aerated engine oil, hence why timely oil changes are especially important on any HUEI engine. Back then, to verify it wasn't aerated, we would start and run the engine at redline (about 3200 RPMs if I remember correctly) for a few minutes while watching ICP and IPR readings and confirming ICP readings would remain steady at around 1800 or so, not some stupid high reading. IPR on a 7.3 at operating temperature should be in the neighborhood of 9 to 11% at idle and up to about 45% at elevated RPMs depending on operating conditions. If you see it increase to 65% then you have a high pressure oil system leak somewhere because that is the max duty cycle. I've vaguely recalled the IPR spool valve nut were prone to falling off into the "valley" too. Wow, it's been YEARS since I've gotten my hands dirty on a 7.3!

[@WatchWesWork]

Some have pointed out, without the injectors firing, there is nothing bleeding off the high pressure oil. So it continues to build until it hits the relief valve. I should have thought of that!

[@stephenvaughen7977]

Wes, I too was eating IDM'S on my 2000 7.3L Excursion. The issue was the rectifiers/diods in the alternator. I found on ebay a heavy duty rectifier for my alternator. US made and supposedly for high amp alternators. (plus I installed a new voltage regulator). Autozone alts were giving me fits, but the real culprit were the high amp alts (Chinese) I bought on ebay. Chinese alts can have dog shit rectifiers. I rebuilt my high amp ebay alternator with the new US made heavy duty rectifier and the problem went away. The IPR spikes you are seeing "may" be related to the rectifier leaking, confusing the voltage regulator into sending more voltage, then the leak stops, voltage spikes briefly, voltage backed off, but the damage is already done to the IPR. Spike voltage fries an IDM, maybe! Good luck!

[@j.c.smithprojects]

what? no push bar on the cub cadet? 50,000 miles and 500,000 miles worth of idling! 7.3 in a van has a larger turbo because they dont have an air charge cooler. it will be interesting to see if the connectors are melted together shorting out the idm. the 25 miles thing suggests to me that it could be temperature and expansion that helps to induce a short. cant wait to see you dig into this one. these are my favorite types of repairs.

[@WatchWesWork]

Yeah, it may well have 20,000 idle hours! The owner says one valve cover was removed and no issue was found. But there has to be something happening and the valve cover harness is such a common failure.

[@paulc.sachsejr.7209]

Watching that seen of you towing the van in gave me vivid flashbacks of my mom and dad at our camp. My dad would be on the Case VAI and my mom would be steering what ever needed to be moved. Thanks for the memories...😂

[@kstricl]

I remember when the ambulance service in BC, Canada started using diesel ambulances. It was around 1991, so the 7.3 IDI no turbo. The news did a story about frustrated drivers having trouble making it to calls in a timely manner, because they could hardly get a hill! My dad was on ambulance when his station was first given the diesel ambulances, but by that point they were the powerstroke, so they were actually pretty good.

[@BudMasta]

i think a lot of places in the US ended up just putting turbos on a boatload of government equipment before the turbo was the standard option. firetrucks and ambulances were having trouble with hills and such.

@@WatchWesWork I've got a 1998 van with the 7.3 liter "PowerStroke" engine. I love this thing, but with 350,000 miles, I'm worried that I should rebuild the cylinder heads and injectors soon (to help it last more than 800,000). The problem is that getting access could mean having to remove the entire cab from the chassis, something I don't have a garage or other facilities to do such work in. These things are a pain in the butt to work on - removing most of the intake air assembly just to change a fuel filter...ughhh.

[@elcheapotravel5914]

Agreed loving it too

[@karlcarnevale4948]

Most states set an age limit on emergency vehicles. As a former police officer our vehicles were replaced around the 100k mark. The volunteer fire/rescue were regulated by the state by age of vehicle. You stated in the beginning of the video that the owners company converted the ambulance to the flatbed. Lots of electrical connections had to be removed and reconnected. Maybe the tech that worked on wiring crossed wires someplace causing a surge to the control module. Sounds also like it ran before the conversion. GL Wes.

[@WatchWesWork]

Yeah, damage from various conversions is pretty likely.

The forklift would never get trapped again as long as you can get the dead vehicle close to the shop door. *Thank You* for the videos. They are much appreciated. 👍

[@Nathan-pw7do]

Sometimes I love electrical problems other times not so much lol. I'm not familiar with those trucks but if it's eating modules I'd be looking for an alternator or ground problem. Nice to see you working with the fam!

[@scottc0510]

Good job, Wes! I agree you still need to find the root cause of the IDM failures before putting this back on the road, or it may very well fry another one in another 25 miles. For what it's worth, I'm a retired career paramedic in Charlotte, NC. We ran 7.3 Power Stroke F-350's for several years but I'm not aware of us having any ongoing problems like IDM failures. As far as I know, the 7.3 power strokes gave us pretty darn reliable service. Ambulances do indeed get a LOT of idle time. We do "central depoyment" with our fleet and "post" trucks at specified locations strategically. We are deployed and sent to fire stations and even street corners (a point close to intersections). In many instances, our tricks are at least idliing the entire shift 10-12-14 hrs at a time. I don't know how the ambulance company (EMS provider) operated where that chassis-cab came from, but I can vouch for the fact that in many areas, ambulances get an INSANE amount of idle time (mainly for HVAC/climate control for the crews). Keep up the great videos, man! :-)

[@WatchWesWork]

Yeah, I assume it has plenty of idle hours. I believe it was owned by a volunteer fire department, so it may have had a pretty easy life.

[@TotallyNormal-]

I had a similar issue with my PSD van.. 3 bad IDMs.. I was using reman units... Turns out they were filling full of WATER!! Ended up getting a new revision from Ford directly... There were some TSBs regarding water ingress on some vans.. but if I were you I'd pop that old IDM apart and see if it's got water inside! All the reman modules I got were all old versions with bad seals... The new revised one fixed me right up! That location gets a lot of runoff from the windshield, and spray from front tire fender area. BTW.. you're lucky that's a cutaway chassis.. you can't pull the valve covers on a PSD van without removing the motor mounts.. but cutaway chassis are WAY easier to pop the body bolts loose and Jack up the cab, than to pull motor mounts and roll the engine back and forth.. it was 21 hours of labor to pull all the injectors and glow plugs on my van...since mine wasn't a cutaway.. good luck man!!

[@TotallyNormal-]

something else to consider - ambulances do a lot of idling.. and the PSD engines vibrate a LOT at idle.. this one may be old enough that it doesn't have the 'auto idle up' built into the ECM - even with that - they still vibrate everything all to hell.. i always zip tile EVERYTHING - wiring harnesses can chew thru themselves on those vans! doesn't hurt to do a shakedown test, and peel back the harness covers and visually inspect all the high voltage wiring as well..

[@ericl7007]

I think the ICP was reading right since the IDM wasnt turning on the injectors they weren't using the high pressure oil which would send the ICP pressure all the way up, right? If you have ever jumped an ipr to close it out of the gate the pressure rises pretty fast and since the ICP disconnected is like a default reading based on a few parameters it read the same as it connected since it was telling its self it hasn't started I need to raise the pressure in case of a leak. Do you think stiction would read about the same as well, at least when cold enough to be an issue. Also, maybe it running on one bank or partial injectors? Since it didn't buzz with the test it was probably never turning them on to use pressure since it should still buzz even if some were disconnected or had some sort of a short. Great diagnoses people were caught up on the exposed wire if the readings were what you needed them to be its a far fetch to think it was so important.

Kind of makes sense why the ambulance company would have gotten rid of the van only having 40k miles on it. Must have wanted to wash their hands of it after chasing electrical ghosts.

[@nerdyrcdriver]

I'm curious about the number of idle hours. I've heard that is usually the big deal with EMS vehicles is time that they spend idling. Back when I pushed carts at a grocery store the fire department would take the ambulance to go grocery shopping. It would be sitting in the parking lot idling the whole time ready to go if they got a call.

[@sstorholm]

Greg Robbins Emergency vehicles are usually replaced by the date, not the miles. Here in Finland they usually have an insane amount of miles on them when they are auction off instead, but the maintenance schedule is usually also quite insane, they replace oil, fluids, belts and all other sorts of wear parts based on the date, not how many miles I’d had. So if you find a used ambulance, try to get hold of the maintenance history as well, it’ll tell you a lot more than the miles. Normal maintenance schedule is usually 12 months between oil changes.

[@WhiskeyGulf71]

Sebastian Storholm Here in the UK they run Ambulances in to the ground ! Since the NHS split the ambulance services in to larger areas there have been reports of major & dangerous faults going unrepaired, they also seem to fail their yearly MOT tests a fair amount, on anything from the trivial to major issues which is not something you would expect to see really.

[@stanpatterson5033]

I live in South-Eastern Ontario, Canada. Here in the province of Ontario, no ambulance may serve in Provincial Ambulance Service for more than to the end of its 59th month. After that, it can be sold to private ambulance operators, such as those that transport patients between hospitals or take patients who are unable to sit in a car or taxi home. Many get through their initial service life just fine, and live on in secondary service for years afterwards. Some get sold off at fire-sale prices because they're not in ideal shape, these often end up in the hands of contractors and such, and have the emerg. lights removed, and become tradesman's vans. I remember being a kid in high school in the early 80's, having a p-t job pumping gas after school until midnight. All the police, fire, ambulances would tank up where I worked because we took the Provincial Gov't card, and because we were open so late when the rest closed at 8, 9, maybe 10pm. By the time I left that job of pumping gas in 1987, they were starting to put diesel engines into ambulances. I remember asking some of the regular drivers for their opinions on diesel power in the ambulances, responses varied but some were genuinely impressed with the power output compared to the 454's, 460's, 360's, even the latest 350, 318, 351-equipped units. The diesels could obviously last longer, make better use of fuel while idling, and weren't as sluggish as most people had expected.

I think, since about 1989-90'ish all ambulance vehicles had to be of diesel power.

The Power Strokes were OBDII-ish in the early years. They did not follow all the standards, so some scan tools will have issues communicating with them. You can reflash the PCM to a later version and get full OBDII functionality. The Autel does pretty well.

Amazing!!! Wes, You sure are talented. I really like watching you diagnose and solve.

[@isaaccharles4051]

Great video Wes greetings from the United States Virgin islands in the carribbean st.thomas I am a new subcriber and I am a journeyman heavy equipment mechanic with nine years of experience in heavy duty trucks and earthmoving equipment your videos are great and educational my dad was a diesel mechanic he taught me most of what I know so far he passed away last year so I am going to get certified very soon and get my CDL soon thanks for the great content and God bless you and your family keep the videos coming

[@robertmcdonald5277]

It's the value cover harness, I sold my 95 f250 with 280000 miles. Running 2 sets or gaskets. The wire harness burns.. Glow plug . the wire would fry on the injector wire. That was my problem.. Worked the tar out of that truck.. Only 1 e40d trans.

[@evadevries2952]

Agreed. That and the cam position sensor are common failure points with 7.3's

[@stephengraves3275]

Liked the "Spinal Tap" reference.

[@DavidWilson-he8oh]

Just a thought.. you didn’t mention it, but did you pull the old IDM apart and look for water encroachment? The placement if the IDM was in a spot that would cause them to flood when it rained or from washing the truck. I have heard of back to back failures because of this.

[@justinsane7128]

I like how you blew on that plug like an old Atari cartridge

[@JoeHynes284]

i love when your wife and kid are in the videos :)

[@gregd931]

The Audubon Society is very proud of you son!!! You are a godparent now!!!

[@kevinoscarson2941]

Idm fail because of shorted injector-bad harnesses(dorman especially they have pinned some harness wrong), battery cables installed backwards or improper jumping/boost charging, poor grounds, remanned idms not to remanned(many idms fail because of water intrusion and they rebuilt them). Or a shorted engine harness, the engine harness was difficult to get a few year back. Im sure Im forgetting something but it has been about 10 years since I have touched a 1st gen powerstroke. Also the early powerstrokes love to give ghost codes, be very careful about live data. We used to tee a gauge into the icp sensor, what your reading from the scan tool is not always what the computer is. The strategies do not always communicate between the ecm and the scan tool.

[@WatchWesWork]

Yes, I have also seen strangeness on the scan tool with these old trucks. Some of the live data is not live, or even data. Especially exhaust back pressure sensor issues.

[@AntonioClaudioMichael]

I agree the engineer's definitely said Hold My Beer While they put that 7.3l Power Stroke in them old van always was a impressive feat @Watch Wes Work

[@elcheapotravel5914]

Very nice, try checking the harness with a load one wire by one there must be a wire corroded inside

[@plumbum48]

Really enjoy the variety of equipment you work on, makes your videos that much more educational and entertaining.

[@waynep343]

@ 4:31 can you see the steel bracket bolted to the lip of the cowl that supports the air cleaner assembly.. that is directly in front of the connector .. and your source of RUB... i have a 96 E250 4.9.. i must have had my air filter and bracket out 200 times.. PS.. the Grey and RED signal return wire. see if that is circuit 359.. if it is.. that is a GROUND Wire for almost all the sensors and transmission devices..

[@WatchWesWork]

I thought that too, but that bracket is several inches from the harness. Someone pointed out that it may have had some garbage in there from when it was an ambulance that has since been removed.

[@frankthespank]

I love the whole family bringing the van in, the men on the tractor and lady + dog in the van, LOL!

[@tuf86sami]

ICP will climb to its maximum Level during cranking on an extended crank to force higher injection pressure if it's so cold it won't start at lower pressure

[@TTT-cm5ik]

The truck has a bad green? Earth wire in the block of wires, easy to see disconnected wire when camera is very close up, hope this helps solving long term problems

[@grosseileracingteam]

That computer is pretty smart. It figured out that there was sum ting wong. Usually an old ambulance is a pretty good rig. Hate working on vans though. A guy came up with a special rigging setup for pulling the 7.3 out of E series vans.The F series cab and chassis make it a lot easier target for the old parts cannon.

[@WatchWesWork]

You can remove the cab pretty easily. At the junk yard they pull the engines by flipping the van on its side and torching the front cross member. The engine just folds down and they can unbolt it.

[@motinerygaming3680]

Man that little lawn mower hauling that van was so funny to watch

[@Dasquadwith6]

I moved my jeep one time with a jd lawn tractor...put a couple skid marks on the driveway trying to get a grip :D

[@joshhoman]

It is amazing that he was able to tow that large heavy truck with a lawn tractor!

[@bluegrallis]

It's an E350 Wes, not that it makes any difference. It came from Warren Ct Volunteer Fire department. I don't have any records from them, but may have the bill for the cooked module replacement, and both were supposed to be OEM rebuilt modules(might be in the glovebox, or above one of the visors?). I'm thinking new valve cover gaskets with a new style clip that won't come loose on it's own might be the way to go. We'll have to talk soon. It was good to hear it run again though 😎

[@WatchWesWork]

Well I got sort of close. I'll get in touch with you Monday and we can make a plan.

[@joemascioni3101]

I had a 97 F350 power stroke. The harness inside the valve cover had worn thru. It caused the IDM to fry 3 times before I finally figured out what was causing it.

[@WatchWesWork]

That'll do it!

[@desdecardo]

There's a high-pressure oil pump at the top back of the motor that's a typical issue. Also, since oil pressure is used to open the injectors, flow of the oil into the high pressure pump is critical. There's a tiny screen on the intake of the pump that clogs. and blocks the pump.

[@WatchWesWork]

HPOP pumps were pretty reliable in the 7.3. I don't know that I have ever seen on fail like the 6.0.

[@aserta]

I think they make extender cables for relays and the like. It's essentially a regular plug that's been gutted and a wire and base comes out of it, about 30 cm long. I'm pretty sure that's what i saw (online during a fleaBay bored out of my mind nights).

[@WatchWesWork]

I could make one I suppose. Might be handy.

[@bostedtap8399]

Quite a puzzler Wes. Great vlog thanks for sharing.

[@WatchWesWork]

Thanks for watching!

[@tractorboy31]

I was thinking of doing the valve cover update on my 97 because i found my under turbo connection getting fried so i replaced that pigtail but if doing again i thought up replacing with super duty gaskets. I just got new 180cc stage 1 injectors installed and new glows. Trk had i believe original injectors with 300k on them. New stage 1s and wow it like a completely different trk. It ran but but i didnt have decent power. Couldnt pass anybody wouldnt get up n go now it does of course with a bit of smoke but looking into an upgraded turbo

[@callen6893]

I’d guess high resistance in the injector circuit. Possibly a bad ground causing high resistance. Maybe try a voltage drop from the module to an injector?

[@WatchWesWork]

I've checked each circuit and they are right on spec.

[@cyberhornthedragon]

the rubbed through wire could that could have been something removed from it when it was decommissioned as an ambulance as for the controller if its failing as it moves id say there's a ground or wire intermittently shorting out... it has been taken apart converted and modded twice now in its life

[@jaysonstoy3645]

My thoughts was a test light/meter poke and not properly sealed back up

[@consaka1]

now that it is running you can recheck all the codes and voltages and grounds.

[@jerrythecoo3295]

Good detective work Wes!!.......👀👏👌👍✌️🍻

[@WatchWesWork]

Thanks 👍

[@bobclarke1814]

Havant got a clue what ur doing know nothing about engines but still love ur vids man thanks for sharing again 👍👍

[@mark-]

You might be on the right track with those worn through wires. Check through all the wiring for shorts, breaks and ground loops. Check for good grounds everywhere as well, you may have to run some ground cables.

[@jeffmiller6100]

Great vid Never would have thought Dorman made something That was reliable 😂

[@kutamsterdam]

Geewizz Wes it really is a family business!,😉 even the lawnmower is chipping in, thanks for the entertainment and as always ... it was a joy to watch you work🛠, hope to see you again soon!, you and your family stay save and healthy

[@WatchWesWork]

Everyone must pull their weight.

[@Nebbia_affaraccimiei]

regarding the crazy ipr readings, i've had plenty of times diagnostic tools mess up the conversion factor between the raw data sent by the ecu and whatever measurement unit they show to the user. double checking the actual sensor voltage with a multimeter and referring to the sensor calibration datasheet is the way to go.

[@FlatThunder]

I am guessing the nick in the orange wire was a test cut to probe. Great video! 👍 I enjoy seeing all the advanced diagnostic equipment. The wireless obd /computer scanner makes me want to throw my handheld unit in the trash.
