Dear Friends:
We are having some problems with my Mazda RX 7 FC 45.

1) First Problem: The engine stop suddenly, after 4 or 5 faillures. Seems to be an electric problem. After this, it was impossible to start again.
We have electric energy in the Fuel pump, we have fuel in the injectors ramp, we have a normal function in he starter BUT we haven´t got any raw fuel in the exhaust after 4 or 5 attempts to start the engine. The motor relay is OK.
We suppose a problem with the Injectors relay. But we cannot found it in the place describe in the manuals.
We also try to found this relay in another car, same model. It was impossible.
Both cars looks like a RX 7 FC 45 Model 1989 or 1990.
Both are equipped with electronic injection but electronic ingnition distributor.
My car Serial numbers are:
FC 1032 200418
We suppose these is an especial series for the South American market bassed in the Australian - New Zeland series. But, with left steering wheel.
The engine number is E 080594.
2) We haven´t found the Pin Out diagram of the ECU connectors.
The ECU stickers shows a number very different than all published in different posts.
ECU is : N368
We really apppreciate any good will orientation.
Thank you for your attention.
