Hey there,



So I have a manual 04 and the check engine light is on and has been on for some time. It started when I tried driving the car when it was cold out, the car stalled because I didn't let it warm up and the light never went out. I didn't think anything of it other than why won't it go out. I brought it to the dealership. I'm not sure if they are or are not always on the up and up. They said the light is because the oil metering pump is gone and that it will cost me $1,500 ! to replace it.



1) Does this sound likely to be the problem ?

2) Wouldn't this part be covered under the extended warranty Mazda put out ? Dealership says it's not internal to the engine so it's not covered

3) They say the part itself is 1,300 ! This is hard to believe...



Any help, thoughts, ideas ?? Thanks so much for the help. Simply don't have 1,500 to spend on this right now.

Which codes is it pulling? That should tell you exactly what it is. Also go to NAPA or Autozone and ask them how much for an oil pump.



An idea (not always a good one):

on my 86 13b I ran premix (2 stroke oil, just put it in the tank at I think 100/1 ratio, but double check that.) because I had no oil ejectors, worse comes to worse, you might be able to do that for a bit until you can get the pump fixed.

Do you think Napa would have a oil metering pump !?? They are just for Rx8's...so I wonder. Do you think they would ?

Other ´ (See DTC P1686 )

yep it needs a metering pump. you can try napa/whomever but chances are they wont have. finding a good used one might be the best option, as its not common.

Thanks !

If it's the same as a 13b, it's located on the front bottom in between the intake and the front of the engine. it's about 1 inch by 2 inches and has a lever coming out the front, and some hard plastic oil injector lines. They are not clear, but not opaque.
