Default Civic only starts if i unplug the main injector

This one has me stumped. The car is an 89 Civic with dual point injection. It will only start with the main injector disconnected and will then continue to run without it. It will also run if I then reconnect the main injector.

Anybody got any ideas what the problem is?

Hi Hawneh, Can you please tell me what the problem was in your car. I'm sure you already figured it out and fixed the problem. My 91 Honda Civic Hatchback is doing exactly the same thing. Thanks a lot in advance.
