How to test a fuel pump. Learn how to test your fuel pressure, how to test your fuel pressure regulator, and how to test your fuel pump.
This video will show you how to diagnose your fuel system. If your car is idling or running weird (high idle, low idle, hard to accelerate, studdering, hard to start) then this is one of the first tests you should do. Diagnose high fuel pressure, low fuel pressure, a broken check valve in the fuel pump, broken fuel pressure regulator, or leaking injectors.
Here is the fuel pressure tester I used: www.amazon.com/gp/product/B005...

@lloyd-qt1mg 2 года назад

Very good instruction up to 4:50 mins - I quote: "vacuum decreases on acceleration NOT increases", as stated in the video. Thanks for all the great videos that you post on RU-vid ... Top Gun!

@williamgriffin8695 Год назад

Throttle closed at idle higher vacuum, wide open throttle lesser vacuum

@CWK090 Месяц назад

I agree. The greatest vacuum occurs at idle. The vacuum pulls the diaphragm to open the fuel pressure regulator which allows excess fuel to return to the fuel tank. As the engine accelerates, the vacuum decreases and the pull on the diaphragm decreases moving the fuel pressure regulator toward closed maintaining adequate fuel pressure. That is my understanding.

@nathangant7636 27 дней назад

Vacuum does decrease upon acceleration, that's what my vacuum gauge shows which I monitor all the time when driving. The highest vacuum tends to be at idle, but it will get even higher when you let the car coast downhill, decelerate on a slope by momentarily letting off the gas pedal. You can buy a 'fuel economy gauge' which is just a glorified vacuum gauge. It's very helpful to monitor it while driving in order to minimize fuel consumption in an engine. You ideally want to keep the vacuum as high as possible at all times for best economy.

@CWK090 27 дней назад

@@nathangant7636 Intake manifold vacuum is high when the throttle plate is closed at idle. If you increase the rpm, by opening the throttle plate, the vacuum will decrease. To your point, intake manifold vacuum will be at its highest when both the engine RPM is high AND the throttle plate is closed like when you initially take your foot off of the gas pedal at a high rpm. That highest degree of vacuum is momentary. That is my understanding.

Whoa, this may have been the best of your vids for me. Most are good process review for me, but this one had far more educational info than I expected.

Now anyone in here knows how to troubleshoot more than most shops (out here at least they just throw parts, it's not their money).

@peteowens3033 9 лет назад

Enjoyed your video. Very well done. I would like to point out that you did explain how the Fuel Pressure Regulator works a bit backwards. The regulator's diaphragm is actual opened more by the higher vacuum transferred to the diaphragm via the vacuum line at idle than when the engine accelerates or operates at higher RPMs. This happens because as the throttle opens the air restriction that forms the vacuum in the air plenum. As the addition air is let in from the air intake it increases air flow and reduces the vacuum. This reduces the vacuum to the regulator allow the regulator to close off more of the fuel that was otherwise allowed to pass back to the gas tank. This increases the available fuel and pressure in the fuel rail allowing the injectors to deliver more fuel to the engine. Just a bit technical but I think it helps explains to those that might have been confused as to why the pressure on the gauge actually goes up when you unplugged the regulator's vacuum line at idle. This is what causes that to happen.

@@michaelsoutherland3023 Yes, perfect fit for that. There's generally a good reserve of vacuum anyway for that. As a kid I sometimes drove the 1936 Chevy flatbed truck. It had vacuum windshield wipers and a vacuum actuated 2 speed rear axle, and the engine was so clapped out it hardly made any vacuum at all. The axle was a nightmare, you had to double-clutch it to get it to shift and it only would shift with enough vacuum which could only happen when you were letting off the accelerator. Lots of grinding. The wipers always stopped in front of the driver's face.

@AlfonsoB1940 8 лет назад

Hi Chris: I'm confused, I've watched a dozen videos on this subject and just when I thought I understood how it works...you tell me that it's to the opposite of what I understood....I thought that in an idle situation vacuum in an engine is at it's highest level..(throttle plate closed) and this high vacuum opens the fuel regulator to the max because very little fuel is needed so what is not used is returned to the tank. When the engine is accelerated (throttle plate open) vacuum falls off and fuel consumption increases and to maintain the pressure the lower vacuum lets the fuel regulator close to maintain the pressure in the fuel rail. I have a problem with a 2001 Santa Fe 2.7 GLS and I'm far away from scanners and vacuum pumps. That's the reason I'm watching so many videos....I'm not saying that you are wrong or not try to be smart...I just need to know.

@markhughes8558 7 лет назад

He does have it backwards, when the throttle is closed is when you get the highest vacuum. I'm old enough to remember vacuum operated windshield wipers that would quit when giving the engine more gas plus he showed high vacuum when he unplugged the fuel rail regulator at idle.

For some reason, ChrisFix doesn't sound right, he sounds sickish

That’s just the way he talked then vs now. In every older video he sounds gloomy. He sounds more hype in newer videos

Awesome video. I was able to narrow it down to the fuel pressure regulator and solve a problem that had been causing me headaches for a couple years. Bad idle and super low mileage. Thanks!
