My 1994 mazda navaho seems to be vapor locking. How do i fix this


You need to know the fuel pressure. Just turning the key to on should cause the fuel pump to put high pressure in the fuel line to the engine and fuel injectors. If the pump doesn't turn on, there is an Inertia fuel shutoff switch in the power line going to the pump, so check that has not tripped.

If hard starting or running poorly problems, you could have a fuel pump that still works but fails to keep adequate pressure- a weak pump that needs replacing. If your Mazda has a fuel pressure test port, called a shrader valve, it is easy to hook up a fuel pressure test gauge to check fuel pressure. Autozone and maybe other national stores rent or loan fuel pressure testers.

I have a Mazda mx3.The fuel pump was replaced.Changed the fuel pump the car will no longer start. I removed the hose coming out on the fuel filter and its getting fuel at least that far.


Why did you replace fuel pump? Did you buy a dealer pump or cheap aftermarket unit? Just because it is new does not mean it is good. Have you run pressure test?

What is the part name for the hose on top of my Protege DX valve cover?


Just the hose or the PCV (not pvc) valve? The hose is probably a dealer-only item - go to the Mazda parts department w/the broken piece and they'll get you a new one. The PCV is avl. @ most auto parts stores - and is cheap - <$20.

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.

What is the name of the part that is attached by a hose to air filter


If it's the small hose connected between the breather element inside the air cleaner pan and the PCV valve, it's called the breather hose.
