How to Test Fuel Pumps with a Scanner / Direct Injection Fuel Pressure Test using Autel Scanner

[@DIYAutoworksNG]

Thanks for watching! So far, confirming that this works on Honda and Acura with direct injection. Will keep adding to this list as I find more information.

[@achap3604]

Thank u for sharing your knowledge and teaching us how to use the autel scan tool

[@DIYAutoworksNG]

Many thanks for watching! Appreciated. 🙏🏼

It's funny how you drop this video exactly when I'm doing a fuel system diagnosis on my car, i don't have a scanner though so im going all manual.

[@DIYAutoworksNG]

Thanks for watching. I understand. What car is it? Happy to provide as much remote support as possible.

[@404notfound.....]

I have the mp 808, this information is excellent!! Tks 🇨🇦

[@chiefdenis]

@@DIYAutoworksNG oh wow, just saw this, it's a kia cerato 07, 1.6L engine G4FC(hyundai gamma), throttle was lagging whenever i pressed it and it would stall at slow speeds with the ac on(very frustrating in a manual), even after doing new plugs, new air and fuel filter, new map sensor, cleaned throttle body, serviced injectors, serviced cvvt solenoid and filter, it persisted. There was no valve on the fuel rail so i couldn't test the pressure, I ended up just changing the entire fuel sending unit to fix the issue, so i guess the fuel pressure was low all the while. Anyway, thanks for your time man, really appreciate the work you're doing on this channel.

[@DIYAutoworksNG]

Glad to hear it's been taken care of. Thanks for the compliment.

[@SuperXxelixx]

I really want this scanner. Thanks I'm watching all your videos using this scanner

[@DIYAutoworksNG]

Thanks for the compliment. It's a really good scanner. Just ensure it covers the brand of cars you want to work on well. It has pretty good coverage though.

[@cmack5713]

Simply amazing!! I must get me one asap!!!

[@DIYAutoworksNG]

Thanks for the compliment! All the best.

good job.tu. wouldve been nice if scanner would have shown some numbers.

[@DIYAutoworksNG]

I know! Certainly would have been better than looking at the progress bar. Give me some PSI numbers 😎

[@Joeelectronicschematicsforauto]

I love you channel and I understand what you're saying but these tests that are being done by autel seem to be tested you're just turning it on and off that doesn't relate to the pressure on the load conditions unless you're turning the car on with engine running

[@DIYAutoworksNG]

Thanks for the compliment! I totally get your point, however, that it tests each of the pumps over a period, I rather think it evaluates the fuel pump under a variety of conditions. Remember, the car must not have to be on for the tool to test performance under load. The tool can command the fuel pump to run at a certain rate to simulate driving under load even though the car is of. Finally, this test was developed by Honda and Autel simply replicated the test from the proprietary Honda Diagnostic System (HDS) which is the in-house Honda solution. I'd like to think that Honda considered testing under load while designing this test.

@@DIYAutoworksNG thanks for your reply I appreciate it again I love your channel and I love your electronic knowledge also

Thanks, mate. Stoked!

Thank you for this very informative video...👍one thing do i certanly would of like to see the " Pressure numbers " i am looking to buy a OBD whith more details...not oh ok all is good 😅 Tks

[@DIYAutoworksNG]

Totally understand. Lol. It's really down to how the manufacturer designed the active test. Not sure the HDS will even display fuel pressure numbers in this test.

[@aymenmohamed1134]

thanks

[@DIYAutoworksNG]

You're welcome!

[@brandon7968]

I can’t perform this test on my sisters 535xi, 2011 if I wanted too. The car will crank but not start, it has a brand new battery in it too. I have no idea if it’s a Failed HPFP or what it could be. The car had a bad EKPS Module and I replaced with a working one and coded it to the car successfully, car ran fine for 3 days then just stopped abruptly and never turned on again.

[@DIYAutoworksNG]

Any codes in the EKPS module now? If the HPFP fails in this manner, I would expect a code or 2. Does the car have any freeze frame data you could check for any recording of fuel pressure reading?

[@IrandoMtz]

Tambien detecta la bomba de alta presion?

[@DIYAutoworksNG]

Yes

[@SuperXxelixx]

Have a question for you men, like I told you in a previous massage I'm really interested in buy this scanner, honestly because your videos are great really helpful how to use this scanner, but what do you think about the lounch scanner same range of price or similar, I'm just a DIY user, isn't not for professional use, but I have many cars and always I fox my family cars does why I'm interested in buy one of this, but I really like to know what do you think about the lounch scanner.

[@DIYAutoworksNG]

Hello. Thanks for the compliments. I really can't say much about Launch since I have owned or used one. I know a lot of mechanics who own one, I just don't have experience with it.

[@chidiebere6131]

Thanks for sharing. Pls where do I get your obd2 scanneror is there any other you can recommend. Thanks as I await your feedback

[@DIYAutoworksNG]

The MP808TS is sold via several channels including Amazon and Aliexpress. I include links in the video description. Others to recommend will depend on your scanning needs and budget among other things. Let me respond to this more fully on the other question you asked on a different video.

[@muhammedcevdedgali8238]

if its works but weak does the scanner tells you ?

[@DIYAutoworksNG]

Once it's out of spec; acceptable working threshold, the scanner will flag it as bad.

[@ryanchristensen1799]

I need a scan tool that will activate the fuel pump so I can purge old gas from my 2013 camaro. It's frustrating not being able to find an easier way of doing this. You can't siphon from the tank due to the rollover ball/ valve and the fuse pump relay is not easily accessible to do a bypass so last resort is a scan tool.

[@DIYAutoworksNG]

Wow. Do let me know how this goes. What volume of gas are you looking to purge?

[@ryanchristensen1799]

@@DIYAutoworksNG I've got 3/4 of a tank maybe a shade under. It's shell 89 octane non ethanol mid grade treated with star tron fuel stabilizer. Some of the gas in there is 4 yrs old since I don't drive it often. I hooked up my fuel pressure tester and what little came out still smells like fresh fuel and has that golden piss color to it.

[@DIYAutoworksNG]

I see. Good thing you added the stabiliser, if not anything, it should take care of water. Was going to suggest adding a gas restore product but you already got that covered. Plus 4 years seems like a long time. Just curious did you try to turn it over?

[@ryanchristensen1799]

@@DIYAutoworksNG not yet, being over cautious and don't want to harm the engine. I ran it last year to drive it for state inspection but haven't since then. I couldn't tell if there was any detonation since I was driving at low speeds (

[@DIYAutoworksNG]

Sounds good

[@carldehoney8633]

Can it be tested if the vehicle will not start and run ?

[@DIYAutoworksNG]

No you can't use this particular test. However, if the car uses the CAN protocol and above, you could get a sense by reading the fuel pressure sensor value in live data just with the ignition on. It's not definitive but should help. Also we shouldn't forget using a traditional fuel pressure tester if the car is not direct injection. There kits you can connect to the fuel hose that leads to the fuel rail, and read the pressure from there.

I guess your subscription ran out before the MK808TS was updated to become bidirectional. You'll need to purchase a license to get the update.
