My RX8 while driving switched off, after I got the car home I realized my fuel pump was not coming on or getting ignition. I them jumped the fuel pump it came on and the car started. But I am unable to rev, does this mean it’s my anti theft system came on ? I checked all fuses and relays everything is good. Only the EGI fuses not getting any power and the fuel pump wire to the pump also. I jumped from the line from the battery as only that one getting power.

If the antitheft is triggered the car/key symbol on the dash will flash rapidly.

It could be the fuel pump resistor. The pump has 2 speeds: low soeed for idle and high speed for everything else. If the resistor assembly that controls the speeds has failed, you might get this result.

But.. if you have no current to the EGI fuse at all that's a bit more weird.

Thanks for your response, where is it to check and how do I check ?

Start here M A Z D A go under Engine, then Fuel System, then there are 2 pages for Fuel Pump resister inspection and replacement.

Thanks, fingers crossed.

keep safe everyone, I’ll keep you all posted -project RX8

the connector to the plug in the resistor has now power in it.

hi it was one of my fuse the EGI2 to be exact. But here the strange thing, when it came back on my mileage went from 160k o 264k miles. Anyone ever had that issue ?

Also, anyone know the right software for the rx8? I am seeing two, regular one and a high performance one.

Sounds like the cluster changed to kilometers. You can switch it back to using one of the buttons at the top of the gauge cluster. You can google for exactly how.
Right software for what? There are 2 power levels of RX8, those sound like the right ones for which one you have. But this isn't something you change on your own.

You need to find what causes the fuse to blow, or it'll blow again. One possibility is the wiring to the post-cat O2 sensor rubbing on the exhaust, heat shield or body.

the issue was my solenoid valve, now it good to go. Now I have rear oxygen sensor code. Also I’m running to rich, would it be oxygen sensor ans well as injectors leaking ?

What is the code? The rear O2 sensor doesn't control the mixture, it's there to measure catalytic converter effectiveness. Depending on the code, the sensor could be failing, or the cat could be and the sensor is telling you that.
When you say running rich, how rich? Are you going by smell or by AFR reading?
