Check your EFI and IGN fuses. If you don't have the fuse cover anymore, you can see the drawing at the same website above.

Also check your ignition components.

We have an '85 FSM sticky'd here for your use; follow the download instructions. The FI section is the one you need.

What maintenance have you done to this rig up to this point? If you've been fooling around with the injector harness at all, the injectors are spliced in with butt connectors. Unwrap and solder those puppies instead. This is a common problem with the older Yotas. SO, once you get it running and it has a funky miss, chances are likely this is the culprit.

That should get you started for now.
