I noticed a couple days ago that my oil pressure was at 0 and i was driving it all day before i noticed. Is the only solution getting a new oil pump? im scared people no oil makes rotors MAD! But that doesnt make sense beacuse the car starts fine when I turn it on and I thought it needed oil pressure to turn on.

o ya its an 1987 FC turbo, and I just did a tune up 3 weeks ago (oil, plugs, oil filter, etc replaced) and the motor has enough oil and it starts up fine everytime but the oil pressure gauge is at 0. I havent been driving it since i noticed and i have an appointment next week to take it to mazdatrix for oil lines and injectors to be replaced since theres a leak right where the oil lines go through the intake manifold. but this problem existed way before the oil pressure problem. and im afraid to take it to mazdatrix with no oil pressure since its like 20 miles away. i need help someone please tell me what to do.

 

Most likely the wire got knocked off the oil pressure sensor, or you knocked something or leaked oil onto the wire to mess the signal up.
If you're really paranoid, get a good mechanical gauge and verify it's "0".

BTW, you'd get a lot more responses if you posted in the 2nd gen section.

On my 87 TII, it still has the original sending unit wire which was brittle and cracking. anyways it grounded itself to the rotor housing on day and the gauge went to 0 pressure. maybe this could have happened while you were giving the car a tune up.

 

thanks for the responses guys this makes more sense. but where can i check if the wires are connected correctly? because i cant find where they are.

 

the oil pressure sending unit it the big bronze color "****" just under the oil filter. the wire will be coming from the harness that runs to the starter and should yellow with a red stripe I belive.
