Hello guys, I'm a new member from France. Bought an rx8 with bad engine that I changed. First plugged the injectors wrong, inversed primary 1s and primary 2s middle. Car ran bad: did not hold idle below 2K rpm, power felt low but could rev to 8k+.

Now replugged the injectors as follows :

Rear secondary ( white blue line , blue black line )
Primary 2 secondary rear ( white green line ,white blue line )
Primary 2 front ( white blue line , blue black line )
Front secondary ( white blue line , green pink line )
Primary 1 front ( light green red line , white blue line )
Primary 1 rear ( light green black line , white blue line ).

Now the car runs even worst: still no idle, won't go past 3-4K rpm and banging sounds.

The car gives me no codes and ignition wiring was double checked, harness and plugs.

Could the blue and black lines of Rear secondary and Primary 2 front be inverted as they are the same color?

Any help or idea as to what could be wrong is greatly appreciated. Can't wait to get it running and enjoy fine balance and handling.

 

im not sure about the injectors but did you swap the engine with one that had a compression test or one that was rebuilt by a pro? did you get one from a salvage yard?

did you reset the e-shaft profile?

Engine is used 40k miles from renowed salvage dealer but no compression test was done so I cannot be sure of engine health.

Tried a new wiring diagram yesterday (not from the diagram) and the engine idle well 2k rpm when cold and then goes down gradually, gets up to 8k+ rpm but is hesitent and does not climb as fast as it should, dies upon deceleration and will hardly start again.

E-shaft profile had been reset with memory.

Maybe the problem came from somewhere else, I repluged the ingnition system in between injector wirings, going to rewire as stated in the mazda manuals and try again.

Thanks for the input!

 

Thanks for the diagram, it is what I had gathered from the manual on foxed.ca. Will reconnect as per the diagram tonight and recheck

 

Did a compression test, front rotor has no compression whatsoever. Going to get a proper rebuild this time. Thanks for the help!
