100 percent I’ve encountered so many problems with this. Well said! Great video!
Thank You!
What if got same simptoms and no error codes?
I’m getting a p2541 code on a 08 maybach the sensor was ohm and reading good what can be the problem
What about 29F2, my 09 535i keeps sending this fault code I'm buying a hpfs next and hopefully that fixes the problem
That's nice but do you have some data as to what makes the sensor good bench mark to work from this thing won't start and the voltage to the injectors show signal but with low voltage if pressure trumps voltage what is the balance readings look like
What are the values it should be reading?
Can you do p0454
Any idea of what’s a p119A upper limit exceeded
What wire on the fuel tank is hot
Very informative. I'm having difficulty with a 99 Mercury Gr. Marquis. I stalled out about 6 weeks ago. Replaced fuel pump/fuel filter. Running but started making wailing sounds so replaced IAC valve. Car ran great. Fuel mileage went up. Car stalled out again. Thought maybe inertia switch tripped. Nope. I bypassed switch just in case. No help. Replaced Fuel Pressure Regulator. The fuel line to rail was completely blocked. Replaced it..Getting fuel to rail but pressure seems too low. Will sometimes barely start. Run rough. Stall out. Thought I may have burned out new fuel pump on clogged lines. Replaced it. Checked ohms on spark plugs and injectors. All are in range. Still won't start. Have not checked pressure at rail yet. Plan too get gauge tomorrow to check. Can you offer some guidance. This is my only vehicle and no $$ for new one. Has been dependable until recent fuel system issues. Only throwing O2 sensor code.
Did you ever figure this out?? If so what was it??

Having exact same problem man
I have a question.my 2001 is saying valve or selinoid.i replaced both and 2 vacuum lines.and the fuel cap cause fuel cap light and engine light is still on.some times it starts other times I have to shoot fuel starter in the intake.it will die at idle sometimes also.no other codes.any ideas,??????
I have a 2015 Chev Malibu with 177000 km and it shows code 0089 and code
0016. Code 0089 says it's the fuel pressure regulator and the 0016
says it's the
Df885 code for Renault duster what Rison please tell me
Morning I have 4g93 single cam and the #3 sparkplug alone fowling the compression test the injector good new spark plug and wires what u can make of it
Fowling? What do you mean by that?. In case you want to say that I failed, check for a good vaccum, if you have a bad reading check everything that is mechanical
Hello. Thank you for your video. Can you give me your opinion on our Enclave issue? We have a 2011 Enclave CXL 2WD. It has 110K miles. Like a month ago it reduced speed on highway and showed "Reduced engine power", when my wife took it to Autozone for codes it showed several misfires. I researched the issue online and ended up cleaning the throttle vary and it worked perfect. The engine light disappeared when I reset the computer. No more issues until 3 weeks ago when were driving on the highway and the same situation happened. I took it to Autozone and the code was "misfire on injector 5". After I kept driving it the engine light disappeared by itself and the car was working fine until today. I was driving very slowly on the park and the same message came to the board, the car lost power and a lot of white smoke. I took it to Autozone and the code read misfire on injectors 1,3,5 and issue with fuel pressure regulator. Do you have any idea what could be the issue with this car?
Make sure you have the right sparks plug, many sparks plug look the same but for a reason some vehicles use a very specific spark plug, ask the dealer what type it uses and try to get a cheaper brand at the dealer, also check your maf sensor, it seems to be working intermitent, avoid chinese electric parts try to buy original, it is better an original used one then a after market version.
Sir can you help the problem of me car because if the sunction valve remove the oil sell the engine are start but wen the oil sell can't remove the engine can't start
You said nothing
I would replace the fuel pump first then the sensor
sir ca you help me i have a hyundai starex diesel crdi, when i take it to the mechanic and scan, it show a code p0191 or fuel rail sensor low, ,my car is showing low power, engine check light, hard start. when we replace it with a new one, and we try to start it wont start, ad shows code p0193 ,pls help me were should i look or what should i test
I have kia sportage 2014 gdi it has the same error code P0193
Can you tell me,What Component Replaces
check the wires,check connectors and wiring towards the ecm, and the connector towards the ecm,
Fuel rail sensor very rearly goes bad, however, if this is the case buy an original one at the dealer or get a used one at the junk yard, do not buy chinese or after market electric parts, is better original used then not original new. Also check for the maf sensor, get the original.
If you have car in a shop and you need this video ao you can fix it please close that shop
What??
It is unreasonable to expect any shop in these days of complex auto systems to already know everything every time. I’m fine with a shop that combines their knowledge & expertise with reading the manual and doing any research they need to to fix my car.
Needs some Tegrity
Terrible did not show how to test it information is for mechanics not for the average person!
to much talk
That isn't helpful at all!
Won't be buying anything from your sponsor, and will advise everyone I know and meet to avoid them👍
