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...

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

@CWK090 Ай бұрын

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 Ай бұрын

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 Ай бұрын

@@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.

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 жыл бұрын

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.

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 жыл бұрын

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.

I also have dyslexia and I'll say the opposite of what I mean. There are 2 types of dyslexia I believe, one is for incoming information like seeing letters backwards when reading. The other type is out going information like giving directions, explaining something, or writing letters backwards. It's frustrating because you know what you mean to say but it literally comes out the opposite.

@John Smith giving directions is always fun. It's weird because i dont try to go the wrong way if I'm driving. I guess it has a disconnect and only effect speech. Shit is weird, it was alot worse when I was younger.

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