When you’re dealing with a no-start complaint on a gas engine, you only have three things to check. Is it getting fuel? Is it getting spark? Can the engine compress the air/fuel mix?
But on a diesel, it’s another story! Watch this edition of The Trainer to learn more!

Excellent presentation! Keep them coming. Never to old to learn 😅and I'm 70!
Thanks for this. My van's been standing for a year or so and the house is being sold next month so you can imagine the worst case scenario. I replaced the battery, did a bit of percussive maintenance on the solenoid and she fired right up!
Always great information. Thank you, Pete.
The first test could be just listen to the cranking. If your battery starts getting weaker after a few times, you have compression
I hope to meet you one day and learn from you 👍
You make it easy to understand that is better than what learn at collage lab .
Thanks Pete, now I gotta go try my FLS sensor on AC coupling and experiment!!!!
Let me know how that works for you!
@@MotorAgeMagazine Used a Nicholson FLS on AC Coupling , I saw no discernable difference.
@@paulpaquette1961 Thanks for the update! What did you connect the FLS to?
@@MotorAgeMagazine Test engine was an L83, using the Map Sensor port. PCV system isolated from Intake, there was no difference, I could reference one waveform and overlay it on the other. When I use thwe WPS the waveform is cleaner, I took 4 captures total, and this engine needs a cleaning.
@@MotorAgeMagazineso what was the no start issue?
KNOWLEDGEABLE Sir Pete Meier Motor Age
Helpful video thank you
From Nick Ayivor from London England UK 🇬🇧
Great video, learned a lot!
Thank you Pete, excellent video.👍
If you are a bit dumbfounded, check that your glow plugs are actually getting power, i was super worried, and it was all the relay that had gone...
When I worked at L.A. D.W.P. we had only a few light duty diesels, both the 7.3L V8 and the 6.0L V8.
The 7.3's ran great in the vans only had one 6.0 that would not start after it was shut off. Relative compression and 48 volt FICM no problem, but the I.C.P. at cranking was supposed to be a minimum of 500 PSI like you said.
The low pressure fuel system was delivering fuel to the HP pump with no problems, I don't remember the reading now. The truck I had was at 250 to 275 PSI for the High Pressure.
I was working on it in L.A., but after one day (and a total learning curve) they took it on a roll back to Mojave.
I had read a lot about 6.0's, and some of their diagnostics.
I wanted to check the Injector Control Pressure Sensor and Control valve as I had read how if they get contamination in them, that will cause a no start. Sadly, the truck was taken before I could do that.
Thanks for the info Pete.
excellent
Great stuff p
does not make sense because the truck started, now do one with an engine not starting and solve it.
How come no one does MAF testing on (like 4 gen Ram) diesels? Just found your videos and they are very informative. I can't wait to do some testing. Gotta find out why ecm pin 80 to my MAF only has 11.4 V, While ecm is getting battery voltage (12.4). Videos very inspiring.
It only has 11.4 the circuit might be under load check with amp clamp
Crystal.. perfect 👍
I have a hilux surf ssr-x 1993 diesel my truck cranks over but dosent start it had a kill switch in it
I got a code P0470 what should I check. Thanks
Where are you! I need help with my Dodge Ram diesel. Thank you for these videos!😊
I'm based in Central Florida but unfortunately do not have a shop that people can bring their vehicles to. But tell me a bit about your issues and maybe I can point you in the right direction.
close the door.
Hey, I have a 07 6.0 that will crank and fire but won’t start. When it fires it dumps out black smoke and kinda smells like something’s burning. I have a few things I plan on checking like the ficm and air filter but was hoping for your opinion. Thanks
Black smoke is an indication of excess fuel. White smoke is unburned fuel. How fast is your engine cranking? Too slow will not allow the air charge to heat up sufficiently to ignite the fuel. What is the battery voltage? Too low will slow cranking speed and can impact FICM voltage to the injectors. There are many factors to look at on the 6.0 - do you have access to a scan tool with Ford capability?
@@MotorAgeMagazine i know it’s cranking fast enough cause it’s firing and there should have been enough battery voltage. I just scanned it and everything looks good. It’s really confusing cause everything that it needs to start is working.
@@MotorAgeMagazine I know it has a high pressure oil leak somewhere but it is still building up enough pressure that it should start
@@nathanhill1525 What is your cranking ICP?
@@MotorAgeMagazine I don’t remember exactly what it reached but it was around 1500 which I believe is what you typically want to see
exselete dianostic tec mui bueno
Surely a petrol engine needs the spark at the correct time
So you did not find any problem except low battery? I have 49 yr old sailboat 1500cc diesel motor needs help
What kind of problem are you having? No start?
@@MotorAgeMagazine Of the serious nature, water in the oil not sure if coolant or raw water, could be head gasket, will try retoruqueing head before pulling
@@chhindz Odds are that if it is the head or gasket, retorquing will not correct or help. Does this use a standalone cooling system or does it continuously pump sea water through the cooling system jackets? I don't know much about marine diesels.
Taking the place of the radiator it has heat exchanger where tubes of non mixing sea water and coolant dissipate heat sea water never entering block. I had an old 420 jaguar which was gushing water from head after a freeze, I tightened head and it ran ok for years after. I don't think it will work either, but no harm in trying except a lost gallon of oil
Hello... What if you have a small air leak in the fuel line leading from the tank to the primer..
I have an L200 pick up...i changed glow plugs, fuel filter, primer pump and i over hauled the fuel injecter pump...
Still takes long to start.....
So the low voltage on a battery was the problem? 🤔🤔
He never said what the problem was. So the video was worthless
3:430ppm
very long and boring
