Dealership was about to charge me $1700 to do this 😂 I just needed the diag to know what the issue was as I don’t have time for troubleshooting these days. Thanks for the vid 💪🏾
Thank you! This was helpful. Never get a code for fuel pressure, but feel oil around fuel pump and couldn’t understand why I had oil on middle spark plug on driver side.
It's a pricy item. Most reuse the tube, and if it was mine I prolly would. Putting the cam in zero or lowest position is most important. Thanks for watching.
I sub because this has been the most helpful video ever found thank you bub for showing this and making this video I prayed for the video I need man idk why it's so hard to find a professional video
Hi I want to see if u could help me out I’m getting a code for fuel rail pressure Malfunction pressure too low p0087 for my 2011 Camaro LS could you help me out thanks
How do you rotate the engine by hand? can you give me a step by step procedure like for example do I need to put the car neutral and take the serpentine belt off? I need to make sure that the cam is down that actuates the high pressure pump and I'm not sure how to rotate the engine by hand to push it all the way down. Thanks in advance for your help.
Ok, key off or battery disconnected. Put transmission in park. Manual transmission in neutral. Put a socket on the bolt on the crank shaft. Using a breaker bar or ratcheting wrench connected to that. Then when you turn the engine clockwise put your finger in the hole where the high pressure fuel pump was installed. The follower cup that is in the hole that the fuel pump mounts in will move with the rising and falling of the lobe. You can feel that with your finger. You want the follower cup to be at the bottom most position. You can turn the crankshaft back a bit and forth and feel the rise after it gets bottomed out. You want that. You want the follower cup to be all the way down. You can take the oring off the old pump and verify that it is in the correct position. Or you can use a measurement tool to register the position of the follower cup relative to the face of the mounting flange. Compart that measurement on the pump to verify. I hope this helps you. Please let me know.
There was codes for low fuel pressure at the fuel rail. I took it to the dealer for a diagnosis. They said the high pressure pump had failed. I also had to replace the pump in the tank. After doing the high pressure pump there was still a code for the low pressure pump. I took it to the dealer because I did not have a high pressure diagnostic tool like the dealer had. In retrospect I think they did not test everything out as they should. I would replace the pump in the tank first. If that pressure is low the high pressure will be low. The obd2 data provided the high pressure at the fuel rail. It has to average above 508 psi. I think that is the number. I'll check later. I also made a video on replacing the pump in the tank.
I have the same engine I have p0300, p0301 and p0050, i did not overhead the car, but why too much white smoke, I am wondering if I change the fuel pressure pump fix my problem. (But I do not have any codes related to the high pressure pump)
300 and 301 are misfire codes, 050 is for the heated oxygen sensor fail. I would fix the oxygen sensor first. Then check the low fuel pressure at the fuel rail before the high pressure pump.
Yes, one in the tank, operated by a module, hits approx 60 psi at the test port on the fuel rail. Then the fuel gets to the high pressure pump and then injectors. If the pressure is low from tank then the rail pressure will be off too.
@@tonyfigueroa54 by putting your finger on the plunger and turning over the engine you can feel when the plunger is in the uppermost position or zero position. I was able to do it with one hand on it and the other turning the crankshaft bolt.
Hello i have an issue with a 2011 camaro. the issue is there is fuel coming out of the solder in the exhaust. I checked fuel pressure which is at 60psi. and im getting at least 4 different misfire codes also a low pressure code for the injector rail along with a hole bunch of other codes. i am thinking its an open injector or the high pressure pump. am i going the right route? was wondering if you could give me some advice?
You will get misfire codes from a malfunctioning high pressure pump. The high pressure can be read with a scan tool. If that is the case the oil (oil filter too) and spark plugs will need to be changed too because they are contaminated with fuel. So far you are on the right track. Let me know how things go so others can follow along. Thanks
@@chriskolar well my oil does smell like gas i just don't want the customer to spend more than he needs to. That's why I'm hoping cleaning the injectors will work. The scanner read fuel rail pressure sensor 449.62, rpm was 676, fuel tank pressure sensor read -16. And i have the same issue i seen on the other video not that heavy white smoke but still some coming out low power indicator on the instrument panel. The only difference is i see the gas leak coming out underneath the car in the solder on the exhaust pipe on the driver side.
@@ahiranquijas9720 The injectors on this vehicle are very high pressure design. You will not be able to clean them without a special machine. If the high pressure pump is defective and the pressure is wrong or low the injector spray pattern will not atomize properly leaving droplets of fuel in the combustion chamber. The route that is the least cost is to replace the high pressure pump. To confirm the quality of the fuel system you should remove the fuel filter and drain it into a glass to see how bad the fuel quality is. If it has water and dirt in there then there may be a contamination problem that a new pump will not solve. Diagnose the problem all the way before putting parts.
@@chriskolar Me again... So i changed 3 injectors that were delivering more fuel, changed oil, filters, and spark plugs issue resolved no more white smoke out of exhaust.
I used crows foot tool. It is very difficult to torque it properly that way too. I used the turn the nut 1/4 past the point of contact principal. This work on most hydraulic fittings. In this case, do it at your own risk. Tightening high-pressure fittings is a tricky deal and can get messed up if done wrong. Too lose it leaks. Too tight the threads strip, the line gets crushed, flare gets damaged and leaks. So you have been warned.
@@chriskolar I have a 2014 Camaro with this same problem gas is leaking into my oil or well I smell strong gas from the oil cap and dipstick vibration is noticeable and the small slight raddleing
Do anyone get the dreaded misfire #5? tune up was done coils and spark plugs.. at first I got a code U code symptom 71 network code it was bad battery now on my scanner my number #5 shows misfire on data section because it's fine running but idles rough I ohm the system I got 60 ohms which is good however I did a inj balance test inj #1 43 psi inj# 2,3,4 53 psi and inj #5,6 48 psi I getting different fuel specs wonder if this is normal been racking my brain for days
Does your scanner show rail pressure? This model has gdi injection. You should have 55 to 60 from the low pressure pump. Pressure is regulated by the fuel pump module via a duty cycle. The high-pressure pump will feed the injectors about 500 psi at idle and vary that on according to demand upwards to 1800 range.
@@chriskolar u know what just came to mind....an 02 sensor voltage should range .1 or .9 or something if I remember seeing it my heater o2 on bank 1 and 2 were volt ranging 0.83 to 0.88 and earlier I saw it drop for a brief second to .77.......... on the milli amp side of it .56 to 58 on all of them
Hi Chris, how are you? I'm coming to you because I'm desperate. My 2011 V6 camaro just like the one in your video has had fuel pressure issues since January. It has misfires, "reduced engine power" throws white smoke into the exhaust. The high pressure pump was changed (the high pressure pipes were not changed) but the problem remains the same. The spark plugs were checked, once in February and they had oil, the gaskets of the rocker cover were changed and new spark plugs, then last week we checked the spark plugs again and they were with some oil back and the spark plugs in black, they were cleaned but still with many misfires. In my channel I uploaded several videos about my car, in the last video you can see the values in real time. I would appreciate any help or advice, thank you very much for your time
Yea I checked your video, frp is too low. If you changed the high pressure fuel pump already then the one in the tank is prolly bad. There is a test port for the low pressure pump on the back of the engine. It needs to be around 60 psi. I made a video on the in tank fuel pump replace.
@@chriskolar With a cousin who is a mechanic we wanted to measure the pressure with the gauge but we couldn't disconnect it from the rail port, it's too hard. I saw in other of your videos that you changed the spark plugs of the Camaro, saying that the low pressure makes oil enter where the spark plugs go, can you please explain me how that is?
@@diegospidy5978 there should be a standard port for testing fuel pressure on the low side from tank. The oil gets too much fuel in it, the pressure is low and when the injector flows it is not atomized properly, this allows raw fuel to enter the cylinder, that washes the oil off the cylinder walls and some gets pushed up past the spark plug threads. This also causes higher temperatures in the catalytic converters.

@@aldo9767 ok cool
How'd u disconnect the harness? I can't see how
@ 15 min mark you can see the plug. remove the pump first then unplug it.
I have 60 psi at fuel rail, camaro cranks fires up dies immediately, also have several misfire codes
Need to check the high pressure with a scanner
maf
So this car has 2 fuel pumps?
Yes, one in the tank, operated by a module, hits approx 60 psi at the test port on the fuel rail. Then the fuel gets to the high pressure pump and then injectors. If the pressure is low from tank then the rail pressure will be off too.
How long will this take would you estimate
With all the parts and the right tools 2 hours.
Sir may i know what the part number is for the hpfp??

Yep, start with checking the low pressure lift pump. If you have a scanner you can check the data pid for the low and high pressure.
How do I know if I need the high or low ?
You have to measure the fuel pressure for the low side first. If it is low, replace the pump in the tank.
What autel scanner do you use?
