My guess is low or no oil pressure.
If you have oil pressure it is working.
how do you tell if your fuel pump is working
Remove oil sending unit and replace with a mechanical gauge to check actual engine oil pressure
oil pump is defective and not working.
Yes, Change the oil pump... If the oil pump stopped working, severe engine damage is likely. A new/ rebuilt engine may be necessary. The only way to tell for sure is to tear down and inspect the old engine.
Apparently you cant get any oil :)
No circulation.
Ensure there is sufficient oil and that the oil pump is working correctly
the oil pump is what pumps the oil, the equivalent of your heart and blood, if your heart stopped how long b4 you die?????
Could you tell me how would you replace the oil pump on a Mazda Protege?
Repair or replace the oil pump, or replace the valves, if the oil pump is working properly.
Two things to check: Is there any oil in the engine? Is the oil pump working? If you remove the dip stick while the engine is running you should get oil all over you if the pump is working.
