@@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.
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.
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
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
That is one expensive little pump too

How did u know it wasn't the in tank fuel filter ?
When I connected the pressure test to the fuel rail it was reading correct psi. I connected it before the high pressure fuel line.
