oil pressure guage in nonturbo 7mge
 

a friend swapped a 7mge from japan into his mk3 supra. his oil pressure guages non functioning now what is up?

Well lets see, did he swap oil pressure sending units? Is he using the unit that came from japan or the one that came with his supra? Because Japs dont use psi. Us lazy americans do.

If he did, than try getting a new one from the dealer. He might have hit it when working near the passenger motor mount.
