Posted by on

  • shameer al-qasem Dec 07, 2012

    can i ask what is the normal fuel pressure when idle and when running? how can i achieve the desire fuel pressure.

  • John Doe Dec 07, 2012

    That one i can,t answer for you.Becuase i don,t work on those cars that much Call the dealer service department to find out, There is no way to achieve desired presure you want, It is preregulated Buy the regulator, End as i told you before there is no setting on it, Quit listening to all your so called buddies that never worked on a vehicle in there life, I was a certified mechanic for over45 years,

How donu bleed the fuel on a 2000 Mazda 626 lx 2.0

You don't bleed the fuel. You have a fuel pressure regulator on the fuel rail that does this for you. Turn the key on 3 or 4 times. this builds up pressure. Try to start the car. If it does start, check fuel pressure. Check to hear if the pump is coming on.

This report comes from the fuel rail pressure sensor and is advising that the pump is not providing sufficient fuel to keep up the pressure or the pressure regulator is not operating correctly( vacuum line if connected) or the fuel filter is blocked or the tank is not venting correctly. IT may even be the sensor itself is faulty

How do I check the fuel pressure on a 2000 model mazda millenia with a 2.3 engine in it


You connect a fuel pressure gauge like this to the pressure rail. Pressure in this car must be between 35 and 45 psi. If pressure is too low look for kinked fuel lines and eventually replace the pump. If the pressure drops down more than 10 psi in five minutes or if the pressure is considerably higher than that replace the fuel pressure regulator. Below the parts that may need testing:


1. Fuel tank
2. Shut-off valve
3. Non-return valve
4. Fuel pump
5. Fuel pump (Transfer)
6. Fuel filter (High-pressure)
7. Injector
8. Pressure regulator
9. PRC solenoid valve
10. Fuel pump relay
11. Fuel pump resistor and relay (KJ model)

1999 Mazda 626 V6 Car has an high idle and when running continues to **** off and drive itself if foot is not on the brake. HELP Please!!!!

Sounds like you have a bad fuel pressure regulator.First pull the vacuum hose off of the pressure regulator and look for fuel if any fuel runs out of it replace the regulator.Then if no fuel ran out, hook a fuel gauge to fuel rail and start engine and look at gauge reading and then pull the vacuum hose off and gauge reading should jump up 5-10 psi if it does'nt replace regulator.

I have a 2004 mazda 3 i with 60k miles. The check engine light came on it says rich air/fuel ratio. Any suggestions?

Check the air filter as a clogged one will cause a rich mixture.
Check that the oxygen sensor has been replaced as this controls fuel mixture.
Check that there are no leaky fuel injectors or the fuel pressure is too high.

That's just off the top of my head what could be wrong with your 2004 Mazda.

My Mazda starts rough and idles real rough with black smoke and smell of gas after warm runs great

Dear Smoker.......Sounds to a trained ear that this little guy is gonna need a fuel pressure regulator. It is basically dumping an excessive amount of fuel with the black smoke and all and once it gets warmed up it runs a little better cause it's out of the closed loop cycle. Check the fuel pressure regulator...pull the vacuum line off of it and if you can smell gas or see gas drippin out....that regulator is junk!!! The pressure regulator is on the fuel rail on top of the motor by the way...this should cure your woes.....if not..please get back to me... I HOPE I COULD HELP!!!
