i dont know what the hell is wrong with my 7 i bought it about 2 months ago and it wasnt running at the time so i took it home and found there was no spark. after that i replaced both coil/igniter's the ecu and still nothing when i turn the key on a wierd buzzing noise comes from under the hood i cant pinpoint it but its down below the intake i also found a little box that sits below the air filter is getting quite warm i have know idea what this thing is but it sure doesnt look like a relay. one more thing is theres a larger looking box directly under the steering column inside the car that constantly clicks when the key is on...
can anyone help me!!??

 

wow sounds like a **** up car well if your cars not starting and there is no spark did you check if its fluded and also what year is you Rx-7.

 

im guessing from your name that you have an 87 n/a.. right? any ways, have you checked your battery? whats your voltmeter read when you try to start it?

 

If you have battery power it sounds like a short somewhere in the electrical system.

 

check to make sure your cables from your battery are connected and not loose specially the pos to the started if hear a clicking noise while turing the key ,your starter siolnoid maybe bad.you can do the screw driver check to see if it will crank just watch out for the sparks

 

the car turns over just fine and its not flooded it does get flooded so i know its got fuel but no spark i noticed some wires looked a little burnt on the side of the motor.
