Interesting info! Had no idea they are using brushless fuel pumps now. Scope to the rescue!
Scope won't find the mechanical wear unless you know what the spec is for a new pump
I am just DIYer And this is the first I have ever heard of a DC fuel pump good info thank you
Awesome video. Love the scope info thanks
Man that was by far the best presentation on this particular topic I’ve ever come across .
Thanks!
Thank you sir for an excellent demonstration! very useful indeed for anyone in the repair business.
I read about these pumps several months ago. The speed and therefore output pressure can be controlled much better by way of the control module. Will be interesting to see how long the control module and it's wiring will last in the salt belt areas.
Thanks alot my Dear
👍more very valuable information as always. Thank you!

Sharing what you know with us great video Thank you, take care and have a great day Sir Pete Meier Motor Age
From Nick Ayivor from London England UK 🇬🇧
great video bro!!!
I stick a stethoscope down the fuel tank filling neck and listen for the motor to spin up. Initially takes just a few seconds to determine what you are dealing with. The Trainer Series Motor Age is the best Automotive Diagnostic TH-cam Channel. Thank you Pete for your hard work in bringing us this critical series.
Thank you! And great tip!!

Did you say the 20-20 vision rule😅 as I visualized my scope
Sure the 3 phase pump may have eliminated the brushes but 19 out of 20 pump failures I have seen are mechanical wear on the pump made up by higher command time. So as a pump wears you will see 5000 rpm commanded and desired does equal that so you have to know what a new pump rpm or command time is. Electrical failures on 3 phase are almost non existent. You have to know the system you are working on
How to test with power probe 4. I did test the fuel pump fuse and then g402. That one has no relay to it it was running by fuel pump driver module. 2016 Chevy Malibu 2.0l turbo 4 cyl
It would be nice to see a pattern with a CRACKED MAGNET!! Im sure it will affect ALL patterns
Excellent. From peru👍🏽👍🏽👍🏽
So what does the waveforms look like if you unplug the fuel pump and front probe the connector is it just12 volts on all 3 wires?
Typically you´ll expect 0 volts with the pump at rest. It then is not pulsed by the FPCM.
On the brushless pump, I read OCV on the one and I would expect the same reading on the other two.
What’s ocv
@@philh9238 open circuit voltage
@@philh9238 OCV stands for Open Circuit Voltage. It's the voltage you measure when you measure across the battery terminals.
