once again my 85 rx7 gs is making a grinding sound when i start my car
i just replaced the starter and the grinding sound stopped for like 3 days and then last night it started again...
its doing it less than before but it cant be the starter again could it?

 

may not be the problem at all that your having, but, i found a grinding kind of noise it was the plate thing inside the distributer cap, it was not snug, rearranged it and the sound went away, anyway, good luck,,,,

 

Have someone stand near the engine bay with a piece of hose in their ear and see if they can find the noise while you turn it over. The starter meshes with the ring gear. Had the clutch out recently?

 

I've got the same problem - turn the key and it grinds. Why couldn't Mazda use a Bendix type starter instead of this old GM-like relic!

 

so then what could be the problem? it was fixed for like 3 days after i put on the new starter but why has it happened again?!?
