have a 91 non turbo any ways the oil metering pump is not always oiling 2 rotor causing car to go in limp mode. mazda told me pump would be $2100 wanted to know if there is any else i can do. the car only has 65k miles and motor comp. tested good

 

Ditch the pump and premix it like a 2 stroke. Go to the second gen archive section there is a whole thread on it.

Horrible advice, without a properly working pump hooked up to the harness it will go into limp mode. You will have to buy a working OMP to solve this problem. Now you can block it off from the engine and premix but you NEED to have it hooked up to the harness.

 

True that true that....

 

I would just post a WTB ad in the classifieds and buy a used one.

 

so how does one test a used omp
