Hi Im new to this site and to the rotary life. I just bought myself a 1987 mazda rx-7 that wasn't running and in ok condition with 125xxx miles on it it turns over fine and the injectors are good as well. At first it was getting spark, but the fuel pump and injectors were not turning on, then the next day the fuel pump and injectors were working just fine but I was not able get spark. The fuel pump has been replace and i just bought a secondhand ecu, because the original one was fried and corroded in several arias. The new one works just fine. SOMEONE PLEASE HELP ME!!!! I am banging my head up agent a wall here.

thank you

Check to make sure you have 12V at the coils on the tan wire (coil side). If not, the coils are not receiving power.

You can key on the car and then spin the CAS by hand to check if the ECU is sending spark signals to the coil. Make sure the CAS is plugged in, connector in good shape.

Check the ECU ground on the top of the engine.

Turns out both my ignition coils decided to go out on me at the same time. does anyone have any idea where i can get new ones for a cheap price (im balling on a budget) ive called a lot of my local jdm import companies, but non of them have fc parts, only fd. i dont want to get some off ebay because that are upwards of $150 a peace. any advice is greatly appreciated.

I find it hard to believe that they both went bad on you. FC coil are usually VERY tough

The car did sit in an impound yard for 6 months and i tested the wires leading up to them, and there all good. if you have any suggestions I'm all ears this is my first rx7 so I'm learning as much as i can.


I really like this club everyone is nice an willing to help.
