Been awhile trying to solve and get back to my single turbo 1993 RX-7 project.

I have a Power FC and the ignition is not firing. I have a modified wiring harness
& a used Power Fc that I bought a while back from someone.

To make the story short, I sent the Power FC to Japan and came back negative.
The tech said my Power FC is good and no problem.

I will appreciate if someone can help and give me some pointers where to look.
I'm determined to solve the problem.I can work in conventional engine but lack of ability in Rotary.

Thank you

 

How do you know is not working? have you tested the stock igniter.

 

How have you tested spark?
Tested the coils per FSM?
Replaced plugs?
Tested wires per FSM?
Tested ignition harness for continuity?

 

First of all...thank you for giving me some possible lead to the problem.
I will do the things you mentioned but I'm interested on the last one you said.
"tested ignition harness for continuity"
Where can i search to find the stock pinning of the ECU?

Before I went to single turbo, my car is running. I put my original stock wiring and plug my PowerFC and still no spark. I'm missing something here.

 

or start by checking the EGI fuse...

but ripping the car apart to start with is ok too.

 

Get the FSM and use it. Mainly section F where it shows most of the wiring.
Get an electronics multimeter if you do not have one, and start checking all wiring starting with the relays and fuses first.

Uses binary testing methods to reduce overall work.

 

Damn your simple logic!!

But yeah, good call.

 

EGI fuses are ok --- just checked it.

In the ECU connector, what pin that gives power to the Power FC?
