Default Tachometer prevents car from starting?

Ok Any help would be greatly appreciated, When i purchased my 85' vette the tach was not hooked up. i found the white wire and proceeded to plug it into the distributor, then when i went to start the car, it would only turn over and would not start. but when i unplugged the wire, it would start right up. can anyone tell me what the problem may be? i would really like for the tach to work, please let me know any possible solutions

The ECU needs tach input data. without, it won't start.
