    Just used this vid to fix the same issue I was having with my 2016 cx-5 grand touring, it worked perfect, even sped up you made it possible to see what hoses to remove and where to place stuff and everything, was my first time doing it and made it simple for me to do and saved me a lot of money thanks!!!! I got my power and acceleration back and check engine light is gone!!!

    Good job 👏
    Did you check with the scan tool what was the hpfp actual pressure readings? Mine doesn't get to 2176psi at 3000rpm as per specs, car runs fine just have fuel trims around 15 to 20 combined ?
    Like your video fast short and straight on the job 👍

      That hpfp reading wasn’t reading accurate which was leading me to believe it was the fuel pressure sensor and the distribution rail. But finally duplicating that revving how it bounced up and down while the throttle was 100% open which I believe actuates the hpfp fully I was confident that’s the issue and not the sensor and distribution rail.
      Because the fps wasn’t reading accurately I should’ve known at that point it’s working properly and the hpfp was the issue
      Thank you so much.

      With the car running if you fully depress the pedal the result was the same or only from start? Also I would be curious to see the pressure fluctuation on the fps and if it happens with the new pump as well 👍

    Is it ok if I bought an aftermarket hpfp since it’s much cheaper?

      @@Mr_T817 how many miles are on your Mazda now? I hate to say the dealer is better because this one failed really around 80k. The good thing is that if you get an aftermarket you’ll know exactly how to fix it if it fails again. I went dealer because the customer was paying for it. If I owed this I would’ve picked an aftermarket or a used before spending the money for a dealer hpfp.

Found the aftermarket on eBay for $200 and an auto shop that will install it for me $150. We’ll see how it goes. Thanks for the response

    Hola mi Mazda 3 no acelera me dio el error p0087 ya cambie la bomba del estanque por que daba menos de 2 bar de presión ahora quiero cambiar la bomba de alta presión pero no se si el eje de leva puede estar haciendo presión en la bomba y que pueda saltar de golpe. Además de cómo hacer para cambiar el sensor de riel sin botar gasolina 10:29

    • @Myguyabq

      What year of Mazda 3? The camshaft shouldn’t go anywhere when you remove the hpfp. No matter what you’ll drop some fuel. To prevent it from spraying take the fuel pump fuse out and start the car and let it run till it dies. That’ll relieve the pressure. Then you could remove the fuel rail and pressure sensor together. Make sure you buy from the dealer on these. Aftermarket has proven worse than the dealership.
      With the info from your comment I don’t think the fuel rail and pressure sensor is the issue. The sensor is reading correctly by throwing the p0087 code.

      Gracias ayer lo cambié yo mismo y quedó súper bien perk decidí cambiar todo al final incluido bomba de estanque sensor del riel y la bomba de alta presión. Además saqué el cuerpo de aceleración donde va la mariposa y la limpié. Eso si la batería que tiene el auto es de 12v 55 ah y 330 acc pero la medí con un probador de batería y me dice que tiene apenas 110 de arranque en frío y que debe ser remplazada
      Agradezco tu video me ayudó mucho

      @@tsunami770 it was around $862 here in NM. A lot of money in my book. I’d stay away from any direct injection. Too much carbon build up on the valves causes problems.

      When I connected the pressure test to the fuel rail it was reading correct psi. I connected it before the high pressure fuel line.
