1999 Mazda Miata: mx5..oil gauge..When I disconnect the wire

This answer was rated:

I have a 1999 Mazda Miata, MX5. I changed the oil sending unit but the needle in the oil gauge does not move up. When I disconnect the wire to the oil sending unit, the needle does go up to mid point. Do I need to replace the oil pump? I can only find oil pumps for up to 1997 Mazda Miata. What's with that? Do only the dealers carry it?

HI,

 

Does the engine have a rattle or knock, either at idle or on acceleration?

knock at idle

Hi,

 

Ok, with a knock I do suspect a faulty oil pump as well, but I would advise to rent an oil pressure gauge to hook up in the oil pressure sending unit to verify that there is no oil pressure before replacing it. I do believe in verifying a faulty part before replacing it.

 

Here is part and link to site you can order it from:

Would the local Mazda dealer carry the oil pump?

Hi,

 

They should, but if they dont have it in stock, they can order it and usually get it in 3-5 days. Dealership parts departments have a limited space for stocking, and usually cut off at 10yrs on parts they carry in stock on any given day.
