8 years later, you may have just solved the long start issue that started happening a couple weeks ago, going to do a fuel pressure leak-down test to see if that's where the issue is. Huge thanks to you, Eric!
As I learned from ETCG in a previous video, look around your injectors for clean, shiny spots. Gas is a solvent, so a leaky injector would cause them. The only video I've found where the guy just didn't happen to have a Schrader valve. This cat's the best of the best.
thanks for the info.I was having a issue with my ford explorer after going over 60 mph the car will start bucking. It was suggested to check for fuel pressure..
Can a check valve leak part of the time then stop leaking, I'm having confusing readings on a cavalier 2.2 ohv. Its not flooding so I don't think its a injector issue and I replaced the regulator but it is acting like its starving for fuel for second under heavy throttle like I'm pumping the gas pedal ?
8:40 "Try to keep everything away from the spinny stuff on the front of the engine." -Eric The Car Guy Great words of wisdom. :) Love your videos Eric. Keep it up.
b safe have fun nd stay dirty thanks eric for all the the videos u post up nd the lil comments on what to check when ur on the job ur helping high number of people out here just of youtube again thanks for all the advise you have giving us ur knowledge in this field of work GOD bless you and stay strong keep ur head up
Thank you Eric! I have been trying to find the fuel pressure spec for my Hyundai Sonata and you just happened to turn to the page I need and I now know my fuel pressure should be @ 39psi. Thank you very much. Long time subscriber for a reason (on my account as this is my partners).
I watched to see if I needed an air compressor like i needed to test my ac for a leak. I bought the kit and didnt know I needed one and at the time didnt have the ability to buy one. Just happen to be ina similar circumstance so just a kit will do. Thanks for keeping the vid up. Im dealing with an intermittent crank no start sometimes holding the pedal down it will start. 02 JunKhrysler Town and Country 3.3l
Thank you for your videos! Allow me to add that your #11 adapter push button also works to measure fuel Flow according to OEM specs, the way it works is that your fuel pump (while is pumping with the vehicle on) should be able to retain a specific fuel pressure while is being drained, and it should fill a specific amount of fuel In a Marked container within a specific amount of time
Thanks for some great pointers, I have an S Type Jaguar that's refusing to start. Went from occasional stall or uneven idle, progressively worse. So, I've now got some ideas to isolate the cause, thanks so much.
great video and nice kit. can you please find me the pressure values for hummer h3 2007. I've searched for that like tens of hours but couldn't find that value on the web.
great video. i'm going to give it a try tomorrow....1995 buick lesabre 3800 v6 engine intermittent stall under acceleration problem...replaced TPS, plugs, air and fuel filters,oil and trany service with filters, pcv valve,gas cap, ect....nightmare!
Great video Eric. I have a 2002 Nissan Xterra 3.3 VG33e gen 1 Got a weird one for you, I've been having an issues with my abs not connecting to a scanner Says no communication. My mechanic is telling me that I'm going to have to start chasing wires [SCREAM] . Here's what happened, I was told to clear the ABS light, I should disconnect the ground to the battery for 45 min. Well I got busy and forgot to hook it back up until the next morning, now out of the blue its throwing a Code P0300. Running like hell. i was hoping that the computer would reset. Well the problem is getting worse. Any ideas what might cause tihs Thanks
That's a neat kit, very cool. I usually just tap into a banjo bolt near the fuel filter or on the rail or something, whichever is easiest, either bolt at the end or the banjo bolts for the crossover looked like juicy targets for that. That kit makes things much easier, though, that clip is very cool.
In Haynes Manual it says, before you remove a cap from the fuel pressure port, disconnect the negative, attach the Gauge and then connect the negative. I didn't see in any film that someone would perform this step. Is it some kind of extra precaution? What can happen when you attach the gauge to the test port. I think this is a general question, but for any chance my car is 2001 Saturn SL2 (has a Standard Schader valve port). Thank you for this film.
Love your vids Eric. I must be wrong but I understood that fuel pressure thing is on the return side and lets fuel go back to the tank. I understood it was a "by pass" regulator" that open at the set pressure and bleeds off anything above that. Either way, looking at the pressure in the manifold is the right thing to do.
I'm new to the channel and I really like your videos. I like how you explain everything you are doing. I would like to see you do a video on how to check transmission pressure.
Eric I have a 2004 Toyota Camry 3.0 liter. No exceleration in gear or in park. Check engine lite on with P 2241 and P 2238 all fusses are good. What you think is the problem. I’m about to do a fuel pressure test.
Eric, thanks for this video. I have been stumped as to how to measure the fuel pressure on my 2002 VW Passat v6 without a port on the fuel line to do the measurement. But, you pointed out something that I had not considered and that is what to do if a leak is suspected anywhere along the fuel supply line. Thanks, again, for this tutorial.
How critical is it to insure every bit of air is completely out of the gauges line for accurate readings? I have a 98 Mercury grand marquis that has a very conveniently handy & located vertical schrader valve on the drivers side fuel rail, but when the gauge is attached on it, there's a fair good chance air can be trapped. DL
@8:40 A hook for caliper is very helpful to hang the gauge on the hood loop. @11:10 During cleaning all the fuel system on 2001 Saturn SL2 I installed a new Fuel Filter fm Amazon (PTC PGF846 Fuel Filter). The filter has internal fuel pressure regulator. After ~ 1 month the car gave a code P0401, which keeps coming, and occasionally it is accompanied w/P0300, P0301, and what is important here P0172. I checked the fuel pressure. Specifications on that car: 40 - 55 psi. Pressure decay less that 8 psi in 5 min. The result is: 8:02pm 53 psi I switched off the engine 8:08pm 36 psi So the pressure decay was 17 psi in 5 min. But that is if to measure from the value on the gauge (which was 53 psi). But if to compare w/specified limits, maybe I need to compare with 40 psi, which is the lower limit in specifications. Then the decay will be in allowed values nothing wrong w/the filter. Haynes says: If the hold pressure is less then specified, but in this film, when that decay was measured you said the pressure should hold, and doesn't deviate from the reading on the gauge. And (@11:20) the pressure hold after the engine shut off on the value, which was on the gauge during the engine running. My question is: Do we measure a decay from the current value on the gauge, or from the lower pressure limit in specs? I measured the pressure before w/old filter, and it was holding pressure, I think the current (measured w/running engine), but I'm not sure. I would appreciate any opinions on this matter. The film was very helpful in my research for the question above, though it weakens my hope that the results of the decay were good. I want to add some related comments on the PTC PGF846 Fuel Filter fm/Amazon This filter caused my car to trip a p0172 code making the car run too rich due to an inconsistent fuel pressure regulator I wouldn't recommend running this one on your Saturn pay a little more and get the wix. Filter has a build in regulator which was faulty. Recommend OEM or Wix fuel filter.
Question. Can you have a zero at the gauge with no start. I tried several times but yes crank no start and no movement at the gauge at all. I would think there should be some pressure
I have a "tire valve" on my old Taurus fuel rail, why not just put a good tire pressure gauge on it? It will measure the compressed air in hose. I know liquid doesn't compress but I'd be close. Wonder if my compression tester would work with right fitting. Guess I'll look into that. Just got a new scan tool, I forgot it probably will tell me what CPU says, gooday mate.
Car mnfr's are getting ridiculous now not putting a shrader valve on the fuel rail or an oil pressure gauge in the hud, or a transmission dipstick on the transmission. Unbelievable. These are critical to monitor and they basically make it so you can't reasonably do it.
I have a 1998 Ford F150 4.2 v6..finding the test port was a pain in the SSS but going thru the same tests for a no start..142000 miles on a new england truck { that isnt rotted out }
+EricTheCarGuy great vid.. I have a dilemma- I have a 1997 Cougar Xr7 with 89k miles, V8, 4.6L, it blew a P1151 code (HO21) sense lean condition. The car idles in neutral at 700rpm but when I kick it out of gear and come to a stop sign, it idles at 500 in gear. All of my O2 sensors were replaced months ago. Well, the engine code disappeared a day later, but I did the fuel pressure check as you suggested. With key in ACC mode, my pressure was 30psi and stayed. The PSI per repair manual says it should be 40psi. So, I started the car, it remained the same at 30psi,..I reved it up and stayed at 30psi....until I unplugged the FPR. When I did that, psi went to 40psi as it should be. Although the PSI increased and stayed,..is it safe to assume that even though it increased, would the FPR still could be Faulty? Btw, the fuel filter was replaced 1k miles ago
Hi Eric, great video as always. I have a 2000 ford focus sohc. My fuel pressure fluctuates according to my gauge. Car idles rough ans stalls. Is the fuel pressure sensor on these cars is also a fuel pressure regulator? Some people says that fuel pressure on these cars is controlled by the pcm. Please help.
Great video a lot of information. I just have a question: on my car 89 trans am 350 5.7 I turn the key to the start position then the pressure is 50psi but then it goes back to 0psi in a matter of seconds and when it's running the pressure is ~ 40psi then I turn off the engine it goes back to 0psi in a matter of seconds, what can I do to keep the pressure?
Hey Eric long time subscriber had a question so on a 2013 Nissan Versa Sv any tips on how to do procedure on that car? Also if you don’t mind would your book have the appropriate psi for that car. Thanks
be great if you could do another video for direct fuel injection engines fuel pressure testing and especially checking change in pressure at idle to open throttle - and checking inlet manifold pressures
EricTheCarGuy. Wanted to verify the PSI requirement for a 2013 Nissan Altima (L33) 2.5L, when I did the Test, it was 53 psi idle. which I looked to a lot a places most have said/typed in automotive threads for Nissan Enthusiasts. thanks for the time of reading this and thanks in advance if you answer my comment.
I have an issue with my Nissan Xterra 2003,. have some performance problem, mostly at idle, what i notice lately is that,. if fuel tank is to full level, no problems at all,, the problems start from half to 1/4 of fuel level,. misfire increases with lower fuel level,. to the point if it reaches 1/8 to get empty, it almost stall,. i'll guess the problem is in the tank,. i will try to do some fuel pressure test,. what do you think?
Erick, jow are you? I hace a question for you, i got my car seat for almost a year and now doesn't want to star so I was thinking to check the fuel pump so I take the fuel pump cap loose and bam the gasoline is coming out from the filler, I took the cap off and let the gasoline get out until stop but what do you think is my problem ?
Thank you for the video. My car is GMC Yukon 2016 with stuck fuel gauge at full. I took it to the dealer and they checked the fuel pump "for some reason" and it was OK. I needed the car to travel so I had them put the car together and I took it. The gauge still stuck and the car running great. What is my issue ?? Is it the instrument panel ?? Knowing that they asked me to come back but I am not planning to. I may go to a different dealer.
On my old 87 IROC, it was protocol to measure fuel pressure ONLY with the adjustable fuel pressure regulator disconnected from the vacuum line. One of the upgrades for a TPI engine was to install the adjustable regulator to boost the pressure. But the pressure must be measured at WOT (vacuum line disconnected). Does that book tell you to check fuel pressure with the vacuum line disconnected or not?
Hey Eric, this is a long shot, but what does it mean if the pressure rises 10 PSI when vacuum is removed from the FPR, but doesn't drop back down once vacuum is reconnected to the FPR? I'm having rough idle on cold start and poor fuel mileage. PSI drop is only 4 PSI over 20 minutes, which is well within spec. Appreciate any feedback, and thanks for the great videos.
What should the gague do if you have a fuel pump that might be clogged? 2013 chevy Traverse is sputtering on the highway and going up hills. No check engine light is on. Thanks if you can help would appreciate it very much
Hi Eric. im a DIYer and was wondering, where did you get your fuel pressure kit? and how much did it cost ? i am looking for one but want to get one that can be used for a wide range of vehicles like yours
hi!thank you very much fir this video, it was very helpfull.Can you please tell me the fuel pressure rating for my mitsubishi carisma 98'?And thank you again for all your videos!
Eric--I've had an engine vibration in an 06 Civic with no check engine light. Replaced maf sensor, and it's gotten better. However at idle, when the wheel is turned idle goes up or down a little, and engine audibly vibrates...
when the ignition is in the on position, is fuel expected to exit the fuel pressure regulator ? I would expect it to be closed since there is no vacume
Check this out - On my 99 Solara 1mz-fe (v6) manual, California - there is another regulator in the tank. I haven't found a return line, so this vehicle may be "return-less" as you say. The return is actually in the sending unit itself, and if there was a return line and you were to "dead head" it, it would not go over 48psi. This is because, there is a regulator inside the tank (right next to the fuel pump) that is directly "tee'd" off of the fuel line right as it comes out of the fuel pump. When the pressure gets to 48, it just pumps / stirs gas around in the tank, blowing it through this black filter thing on it's outlet. Do you know (officially) what these parts are called? The Fuel Pressure Regulator I thought was on the fuel rail as you described - I tried looking up the DENSO numbers on Google, can't get much of an answer (it's called "regulator" too). On a 99 Solara V6 - is 48 the pressure it's supposed to be, or is this perhaps a MAX pressure regulator of some sort? I found this out because the gas gauge on my car wasn't working and didn't want to spend $175 on a new fuel gauge sender, so I just bought the whole assembly from a junk yard. I found out after - my car ran better, and the OBD2 emission monitors passed right away (except for the evap, which passes - and the cat, which I'm trying to find out why it still goes "pending fault" once a while - I stopped the active fault after I replaced the o2 sensors, but I have modified exhaust headers, and they did a crappy job of welding the EGR tube onto BANK 1 header. Anyway
Ok as we are reviewing the subject with fuel in it...... as cleaning engine parts with diesel is very effective, as a friend in the army tells me that they use diesel for an engine flush, wich he tells me that it helps clean lifters oil squirters ect ect. Obviously the main process of an oil change will definitely take part ! What are your thoughts please?
What does it mean if fuel pressure rises 6-10psi after being shut off, then drops back down to operating psi after about 20-30 min? Ive read its normal. 02 E250 5.4
I like to see your videos thanks for help in in auto repair. I have a navigator 98 and windshield washer fluid comes on the read glass an on the front, does not what can I do
Car starts fine in the morning but if i drive it for a while it hard cranks and I have poor acceleration, sometimes idles a little low when problem occurs... could this be fuel pump? I've replaced a ton of stuff so I'll list them if you want.
Hi Eric, This morning my 2010 Honda Odyssey got these codes: P0301, P0302, P0303, P0304, P0305, P0306 and P0300. The van was shaking a little bit in the morning. The check engine light didn't come on. The spark plugs were replace about 3 months ago. I was told that it might be my fuel pump. Any suggestions? Thank you.
Eric, I have Silverado with the 6.0 that is throwing a P0300 code. I've rented a fuel pressure gauge. Do I monitor the pressure when the pump is priming or after? As soon as pump is "off" and key still on it drops immediately from 58 to 52. Which one should i verify correct pressure?

But if to compare w/specified limits, maybe I need to compare with 40 psi, which is the lower limit in specifications. Then the decay will be in allowed values nothing wrong w/the filter.

He doesn't reply ...
I have an issue with my Nissan Xterra 2003,. have some performance problem, mostly at idle, what i notice lately is that,. if fuel tank is to full level, no problems at all,, the problems start from half to 1/4 of fuel level,. misfire increases with lower fuel level,. to the point if it reaches 1/8 to get empty, it almost stall,. i'll guess the problem is in the tank,. i will try to do some fuel pressure test,. what do you think?
I’m so fucking glad you work on that 4.7 Runner so much. You’ve saved my life quite a few times. Thanks dude. For real.
Erick, jow are you? I hace a question for you, i got my car seat for almost a year and now doesn't want to star so I was thinking to check the fuel pump so I take the fuel pump cap loose and bam the gasoline is coming out from the filler, I took the cap off and let the gasoline get out until stop but what do you think is my problem ?
Thank you for the video. My car is GMC Yukon 2016 with stuck fuel gauge at full. I took it to the dealer and they checked the fuel pump "for some reason" and it was OK. I needed the car to travel so I had them put the car together and I took it. The gauge still stuck and the car running great. What is my issue ?? Is it the instrument panel ?? Knowing that they asked me to come back but I am not planning to. I may go to a different dealer.
Thank you so much for providing a very useful and well explained video!
On my old 87 IROC, it was protocol to measure fuel pressure ONLY with the adjustable fuel pressure regulator disconnected from the vacuum line. One of the upgrades for a TPI engine was to install the adjustable regulator to boost the pressure. But the pressure must be measured at WOT (vacuum line disconnected).
Does that book tell you to check fuel pressure with the vacuum line disconnected or not?
Where did you buy your fuel pressure gauge set from? Mine sucks and i saw yours now i want it lol.
How about checking the flow rate of the fuel? With that nice tool you had hooked up it would be easy, right?
Where can I get a book, like the one you've check for specifications on any car or truck.
Can you do a fuel pressure test on a Honda pilot? I have a 2003 pilot and I don't know where to test it and there's nothing on the web
Hey Eric, this is a long shot, but what does it mean if the pressure rises 10 PSI when vacuum is removed from the FPR, but doesn't drop back down once vacuum is reconnected to the FPR? I'm having rough idle on cold start and poor fuel mileage. PSI drop is only 4 PSI over 20 minutes, which is well within spec. Appreciate any feedback, and thanks for the great videos.
Great demonstration
What should the gague do if you have a fuel pump that might be clogged? 2013 chevy Traverse is sputtering on the highway and going up hills. No check engine light is on. Thanks if you can help would appreciate it very much
What is that part called at 7:21? I know it's part of the kit, but if I want to buy it separately, I would need to have some key words. Thanks!!
Great video. A question- can low fuel pressure cause engine pinging ?
Isn't that valve with the green cap at 5:23 right next to your hand the shrader valve?
hey Eric quick question.... if you lose pressure when pressing the gas does that mean bad fuel pump? or regulator
Thanks for the upload Eric. As usual they are informative
Very good as usual. Well done Eric
Superb sir thanku.most helpfull.steve from the uk.
Eric I have a couple of test kits neither have that many connecters. what brand is your test kit and where who carries them.
Hi Eric. im a DIYer and was wondering, where did you get your fuel pressure kit? and how much did it cost ? i am looking for one but want to get one that can be used for a wide range of vehicles like yours
google it. OTC fuel pressure kit and look for a kit with a lot of fittings. Amazon, Ebay are 2 of a multitude of sites that sell these kits.
Yea that work light on the hood looks awesome u should do a review on it
hi!thank you very much fir this video, it was very helpfull.Can you please tell me the fuel pressure rating for my mitsubishi carisma 98'?And thank you again for all your videos!
Thank you man, good clear videeo and well explained.
What if your vehicle won't start? Can you still check with ignition on?
Eric--I've had an engine vibration in an 06 Civic with no check engine light. Replaced maf sensor, and it's gotten better. However at idle, when the wheel is turned idle goes up or down a little, and engine audibly vibrates...
at what rate should the fuel pressure bleed off *thru the fuel pump* back into the tank when the engine is off for a normal, working fuel pump?
My car starts but shuts off within seconds. Could it be a fuel pressure issue? I am able to rev up the engine once or twice before it shuts off.
when the ignition is in the on position, is fuel expected to exit the fuel pressure regulator ? I would expect it to be closed since there is no vacume
To check the fuel pressure put the gauge before the fuel regulator?
Check this out - On my 99 Solara 1mz-fe (v6) manual, California - there is another regulator in the tank. I haven't found a return line, so this vehicle may be "return-less" as you say. The return is actually in the sending unit itself, and if there was a return line and you were to "dead head" it, it would not go over 48psi. This is because, there is a regulator inside the tank (right next to the fuel pump) that is directly "tee'd" off of the fuel line right as it comes out of the fuel pump. When the pressure gets to 48, it just pumps / stirs gas around in the tank, blowing it through this black filter thing on it's outlet.
Do you know (officially) what these parts are called? The Fuel Pressure Regulator I thought was on the fuel rail as you described - I tried looking up the DENSO numbers on Google, can't get much of an answer (it's called "regulator" too). On a 99 Solara V6 - is 48 the pressure it's supposed to be, or is this perhaps a MAX pressure regulator of some sort?
I found this out because the gas gauge on my car wasn't working and didn't want to spend $175 on a new fuel gauge sender, so I just bought the whole assembly from a junk yard. I found out after - my car ran better, and the OBD2 emission monitors passed right away (except for the evap, which passes - and the cat, which I'm trying to find out why it still goes "pending fault" once a while - I stopped the active fault after I replaced the o2 sensors, but I have modified exhaust headers, and they did a crappy job of welding the EGR tube onto BANK 1 header. Anyway
Great video brother. Very informative
Ok as we are reviewing the subject with fuel in it...... as cleaning engine parts with diesel is very effective, as a friend in the army tells me that they use diesel for an engine flush, wich he tells me that it helps clean lifters oil squirters ect ect.
Obviously the main process of an oil change will definitely take part !
What are your thoughts please?
What does it mean if fuel pressure rises 6-10psi after being shut off, then drops back down to operating psi after about 20-30 min? Ive read its normal. 02 E250 5.4
I like to see your videos thanks for help in in auto repair. I have a navigator 98 and windshield washer fluid comes on the read glass an on the front, does not what can I do
Thanks! My 1uz is the older yet smaller brother to this
Eric what do you mean by "direct injection" as opposed to what other kind of injection?
Car starts fine in the morning but if i drive it for a while it hard cranks and I have poor acceleration, sometimes idles a little low when problem occurs... could this be fuel pump? I've replaced a ton of stuff so I'll list them if you want.
Nice camera work! And of course the info is great too!
Hi Eric, This morning my 2010 Honda Odyssey got these codes: P0301, P0302, P0303, P0304, P0305, P0306 and P0300. The van was shaking a little bit in the morning. The check engine light didn't come on. The spark plugs were replace about 3 months ago. I was told that it might be my fuel pump.
Any suggestions? Thank you.
Eric, I have Silverado with the 6.0 that is throwing a P0300 code. I've rented a fuel pressure gauge. Do I monitor the pressure when the pump is priming or after? As soon as pump is "off" and key still on it drops immediately from 58 to 52. Which one should i verify correct pressure?
What would be a cause of fuel pressure dropping rapidly after turning the engine off? 3.8l v6 mustang. I suspect the fuel pressure regulator.
