@user-uj1xg7hb2u My Pleasure!
FANTASTIC VIDEO. Great process of elimination with TESTING and not part swapping.
@frankdaiii6403 Thank you!
Before actual diagnose I thought the problem was the crank sensor and you proved me wrong. From South Africa
@wsnxumalo6707 Thanks!
Very good information. I have been fighting this '96 for two weeks. Thank you.
SamofCR My Pleasure!!
Video opening the broken module! Several good videos on UA-cam showing water intrusion location. Would be interesting to know root cause of failure in module. Extra points for soldering on new caps and the transistors to fix the old one. Nice work!!
@jeremyjsword Thank you!
Very impressive straight to the point and easy to understand
Tracy Lenderman Thank you!!!
Great video
You are the man.
I wished you were my neighbor.
I have a 1999 F-350 7.3L that I have had for 15 yrs that I love. It’s been a great truck.
I really would like to have as my go to professional when I need help.
@DANIELROMERO-cv3tu Thank you!
This was a great video! You did a great job explaining and diagnosing the issue. Thanks for sharing your knowledge.
George Stennis thank you!!
Thank you this was a great video and I love how you went step by step on explaining how to test it I have the same issue vary knowledgeable guy

Excellent diagnosis thanks for sharing your knowledge bless you perfect job
Rene Mata My Pleasure! Thanks
My 7.3 it was my idm. Mine retained water. Got a new one and it’s been working. I had the ford dealership test it and they did fix it. IDM replaced 😊
@OutdoorTonez Oh cool!
Great job like how you walked thru the testing
Joseph Murray Thanks !
This was legit.
EXCELLENT JOB!!

yeah muy friend my trok is cranking cold 🥶 times no is start thank you 🙏 from Guatemala 🇬🇹
@miguelmendez4690 My Pleasure!
thanks for teaching me how to tell if my icm is good or bad. very good video and very good teacher. now i have figure out my problem . not the icm ..... how do you test the pcm?
Sherwood Rogers My Pleasure!! it's pretty much the same process!!
Great informative video. Is there a way to do the "buzz test" without having the diagnostics computer?
Richard Varner no you can't! you have to have a scan tool capable of doing that test!
i got a bluetooth OBDII adapter and forscan on my iphone to be able to do some of the diesel specific tests and view data to/from the PCM & sensors.
Thank you for this information
Excellent video. Trying to diagnose my son's 7.3. crank no start, I'll have him check powers and grounds. Fuse #22 big 30 amp, no power at either side of fuse, any thoughts?
Kelly Simonson check main fuses or fusable links on the power cables coming from the battery!!
Had my 96 7.3 die on the highway... fuel bowl heater shorted out and blew the 30a fuse. Replaced fuel bowl heater and fuse and fired right up. The old heater used a looped wire which broke loose and caused the short.
You make a good informative video. Thank you

@@KITS_Auto_and_Truck_Repair do you need a special scan tool to do the injector test or can autel do it?
Excellent troubleshooting video. My truck was running fine when I shut it off 2 years ago. Upon starting it recently, it started, ran rough and died. Now, no start. The ICM was full of water, swapped it out. Replaced the cam position sensor, fuel filter, IPC, and put a gauge on the HPOP. Finally towed it to a diesel shop, and 6 weeks later, I owe more than the truck is worth, and it still isn’t running.
They’re telling me that it needs 2 injectors, and if one stops up, it can prevent fuel,from getting to all of the injectors.
Am I being had by this shop?
nclaytonc I wonder why they replaced all those parts!!
@@KITS_Auto_and_Truck_Repair in all fairness, it was I who replaced the parts before I finally decided to take to someone else. The Injector Control Module was full of rain water, so I condemned it. The IPC, cam sensor were cheap enough, and the fuel filter had 148k miles on it.
I talked at length with the mechanic yesterday. He was a Ford tech for a dozen years, and trained other techs on the 7.3, 6.0, and the 6.6. I was impressed by his knowledge and thoroughness, but the bottom line is we’ve spent a lot of money and it still does not run.
The only parts that don’t check out at 100% are 2 injectors (#4 and #6).
Right now, I’m waiting for the shop manager to come back from vacation so we can agree on a not-to-exceed repair cost.
The no-start condition is being blamed on the tank of bio-fuel that has now been in the tank 4 years. I didn’t know that bio-fuel has the same issues as ethanol gasoline when it sits too long.
@@GenerationsLodge ok!
@@KITS_Auto_and_Truck_Repair any thoughts on the bio-diesel thing?
@@GenerationsLodge I don't know much about bio-diesel
Learned a lot.
Great video! 👍🏿

Like your diagnostic tool. Where do I get one?
@chrisrel9750 Thanks! you can get it online from snapon.com
Great job! Is there any way to diagnose without the scan tool? How can you test the signal to the injectors without that type of scanner?
@berniemac8413 Thank you! you a good scan tool to do that test!
@berniemac8413 Thanks! you need a good scan tool to do that test!
@@KITS_Auto_and_Truck_Repair would any bidirectional scanner work? Or which would you recommend? Got a 05 sprinter that I’d like to use it on as well.
Very good explanation thank you

imurtroll Thank you!
How to you test the 12v supply side of the injector driver for a shorted driver with a test light? I connected the test light to battery positive and and touched the test light to injector driver 12v supply to injectors. The test light was flickering. I know the light should only flicker on the control side when the pcm pulls them to ground. But it shouldn't flicker on the supply side, positive to positive should it? Did I do this right? Have I confirmed supply side injector driver shorted? Need a second opinion to confirm I did this test right please.
@michaelcox2648 I didn't understand your question! are you trying to test the power supply to the injector or the injector driver module?
@@KITS_Auto_and_Truck_Repair it's the injector driver module with injectors unplugged the test light is flickering. Does that confirm injector driver supply shorted? Hope that makes sense.
Awesome diagnostic
@JuanCastillo-sb7fp Thanks!
Great video very Informative
@bennyburgess4036 Thank you!
Your story follows mine, except that I have a power/ground failure. The PCM is not sending the enable signal to ground the ground side and power the IDM. Is there anything other than a blown PCM that can keep a good PCM from enabling the IDM?
@dougmartin6717 you might have an open wire between the PCM and the IDM
@@KITS_Auto_and_Truck_Repair that was the first thing I checked. Connection fine. Inspected the PCM board. Except for some rubber coating that's peeling away in places, nothing looks or smells burned. Already ordered a new PCM from Rockauto, but feel like that's a flip of the coin. I am just wondering how smart the PCM is, and if it would inhibit the IDM if it detected say, a short in one of the sensors or driven outputs. And be perfectly fine otherwise. I also wonder how easily its programming gets corrupted.
Great video!
Jason Core Thank you!!
Ben your doing the buzz injector drive module can you here the individual injectors buzz without the scanner
Lloyd Martinez No! You can't hear them individually without a scanner!
what kind of scanner is the one you used for the ford diesel? could you give the model
pedro gutierrez Sure!! I used the Snapon Zeus in this video!
Thanks great video and a way to go step by step had same issue 💪💪

Ashif Mohammed Thank you!
I ran my 96 out of fuel and was able to get it to start yesterday but I had loss of power and then turned off. I charge the batteries and now I have a crank but no start. Could this possibly be my issue as well?
@kingrichard_1093 Make sure your fuel bowl is filled with fuel
Great video, subscribed and saved video for later use. Very informative.
Gregory Lancaster Thank you!!!
The injector module relay number 303 in my 2002 Ford F350 diesel lariat is buzzing very loudly and the truck won’t start should I replace the relay or head towards the module itself time sensitive
John Bevil check power and ground at the injector module first!
Great vid with good explanation!
JB Thank you!!
Awesome video !!!
@terryusry2076 Thanks
did your scanner hook up to OBD1 or OBD2 port. i thought OBD2 was 96 and newer?
@peetky8645 I connected it to an OBD2 Port in the truck, I believe OBD2 was 91 and newer!
why is testing the injectors next when it cranks and no start? can there be elec problems or good pressure at the fuel bowl but maybe fuel not getting to injectors, and if the orings are bad on injectors wouldnt the oil be thinner and fuel in oil??
@ronaldlemons2836 that's possible yes!
So with crank no start, the injectors are the next step?
Can the idm still be bad even if the buzz test works?
@dawaken4740 Yes! if the buzz is not loud!
Very knowledgeable. Great video.
Jeramie T thank you
Hola amigo tengo una falla muy parecida a la tuya pero en mi caso el modulo si hace la prueba de los inyectores pero sigue sin arrancar, algún consejo? El escaner marca el código P0200

@imfamemitotero7171 My Pleasure!
I have a 7.3... had the same problems. I replaced the cam shaft sensor twice...second time I used a ford part. Didn't fix my problem.... I replaced the ICP sensor and it would not start. Put the old one back in and it started, but ran rough. Swapped the bad sensor, put it in and it ran like a charm. The next day the truck would not start. Any idea what could cause this? I am going to try yet another sensor for the ICP. This blows my mind how it worked yesterday and not today. Thank you in advance
Hip Airbrush you should check your injection pressure, sounds like you might have a defective IPR or bad high pressure oil pump... get a pressure gauge and install it on the ICP sensor opening, crank the engine and see what kind of pressure you get
When I get my truck it coming with 2 battery but I'm desconet one of them ...can you please tell me if was grown what's I did,??
Dehiby alvarez I didn't understand your question, sorry!
I have something similar but the power goes out and later comes back new relay all the fuses are good I put in new Glow Plug Relay Solenoid for 1995 7.3L Powerstroke and it turns on for 5 seconds and turns off and doesn't turn on for a while
@hectorgreen515 Check the injector module!
@@KITS_Auto_and_Truck_Repair no have positive energy in pcm
What scanner do you use? Thank you.
Keith Whitlock I'm using the snapon Zeus
K where does the IDM receive it's power from I have checked everything I can think of replaced the cam/ Crank sensor the oil/fuel pressure whatever sensor I don't have power to the IDM or the fuel pump
Donald Sterling check your fuses!
@@KITS_Auto_and_Truck_Repair I did I have like 5 with no power
But I don't have an owners manual to see exactly what they go to
Ok I checked all the fuses I have 5 that I have zero power to on either side of the fuse I don't know how to check relays and I have 4 in the fuse box and 2 under the hood on top of the drivers side front fender that I have found so far and looked for bad or chewed wires and haven't found any

My 94.5 psd isnt showing that service engine light that you talk about in this video when you first crank It? I have a new idm and pcm, any recommendations on what to do next?
Marcus Lopez did you replace the PCM? if yes, why did you replace it? you can start by check powers and ground at the pcm, to see if it's been powered!!!
@@KITS_Auto_and_Truck_Repair I replaced it because of a leaking swollen capacitor, check engine light and wts does come on just no service engine soon
@@cub862001 most vehicles only have one light, it's either the check engine light or the service engine soon light, if the check engine light is on it means the engine computer is most likely been turned on, was the new PCM calibrated or programmed?

Hey i hava a question i have a 7.3 that only 4 injectors has power. The other 4 injectors that are in the passenger side that harness dosent have power what can it be and is not the valve cover harness 8 injectors are new. I change both computer too and still doing the same thing
Melody Carrero it sounds like you have a wiring issue, check power and ground at the IDM, if you have power and ground for the injectors at the module , you should also have it at the heads, on both sides... be careful checking those wires, there is 200v on them/ the other possibility would be the module itself,
Hi man where are you located I’m in Texas and I may need your services
Ubiliado Cadenas I would like to provide my services to you but unfortunately I'm too far away from you... I'm located in Maryland
What if my truck starts when the engine is cold but when it's hot it will shut off even when driving it
Danny Swanger you could have a failing IPR or a fail injector module as well, and list can go on and on and on, so I recommend you take your truck to a pro mechanic so they can diagnose it!

@@MrMsMexican that's weird, disconnect the Injection pressure sensor on the driver side cylinder head and crank it with the sensor disconnected and see what happens, if that doesn't help, crack the fuel lines going to each cylinder head on the back of the engine next to the turbo then crank the engine, fuel should come out of those lines while you're cranking it...
