What is the problem when you can't get no firing to a 2004 Mazda rx8?

Answer 1

That question has far too many answers. There are four spark plugs. They are designated as "lead" or "trailing". This requires two different kinds of plugs. (I use NGK Iridium plugs). Each plug has its own ignition coil. The spark plug wires, the coils and the plugs are the place to start. The wiring connectors to the coils become brittle and are prone to breakage when removed carelessly. Never pull directly on the wires! Try cleaning the connectors with carburetor cleaner spray and a soft brush or cloth before carefully disconnecting the coils. The engine is prone to flooding, and a wet plug will not fire. The ECU (computer) is something else to consider, as is making sure that the crankshaft sensor on the drivers side of the engine by the crankshaft pulley is clean and the wires are intact, as this is where the firing signals originate. There is alot of good information to be found in researching Mazda RX8 sites, there is also alot of bunk. Pony up the dough to buy yourself a Clymer's or Chilton's manual and use common sense. Designed by engineers, assembled by idiots. Take your time, do your homework. Vice-Grip pliers, a big flathead screwdriver and a hammer are seldom the proper tools for repairing today's automobiles.
