Well im getting no spark or fuel. The apexi commander is stuck on the apexi screen. you cant go into the settings or anything. The car cranks but wont start up due to no spark or fuel delivery. car ran perfectly fine last week. Wire grounding out maybe or maybe its my power fc? Anyone have a problem like this before? Im trying to get a buddies 5 speed computer to see if it starts. I dont think its the power fc though. im thinking its a ground that came loose or a short.

I had the same problem this weekend, and it ended up being a ground. Check out all of the grounds

the commander being stuck at the Apexi screen is a common issue. There's a brown wire inside the commander that breaks. It's as simple as resoldering the wire to fix it.

Here's Dale Clark's FAQ. https://www.rx7club.com/power-fc-forum-47/new-version-powerfc-faq-573647/

No fuel and no spark but it cranks, have you checked the EGI fuses?

all fuses are fine. Im gonna check all the grounds and see what happens. Then check out that brown wire within the commander.

Im having the same problem ( no spark) after installing my engine. Check the CAS Plugs aswell.

Okay im kinda scared now. We replaced the Power FC with a stock 5 speed computer and it starts up. Plugged the power Fc back in and it wont. The Commander is just stuck on the Apexi screen. When the power fc is plugged in the car wont get any spark or fuel. When the 5 speed computer is in it does and thats why im scared. I refuse to believe that my power fc is fried from NOTHING. One day it runs fine and the next it doesnt???? Has to be some kind of wiring issue. Dont really know where to start but i need help. Which pin on the power fc gets 12 volts? Is that where i should start?

Im trying to get my buddy over so i can try his power Fc. If his starts my car then am i in trouble? Do power fc's just go like that? I bought it brand new so i cant see why it would, only 2 years old.
