my check engine light will randomly come on. I have the old School diagnostic light. with the ignition off I placed a jumper between terminals A and B. Turned the ignition to on (not start) and the light blinks twice and stays on. I have no idea what that means or if that's just some kind of error. any ideas?
 
My stock '85 has no 'check-engine' light.
Is this a FI conversion or??

I was wondering the same thing. Figured since I removed the stock carb and disconnected the computer maybe that was why I never got a code
 
I'm not 100% sure but i believe it is a EFI conversion. It has a TBI Rochester 220 on it. I know the EGR was removed and blocked off so it def had some mods to it. I'll prob just let it be and drive it
 
Post up some pictures so we all can see.
