If you can do what I did on my GTO. I bought a key switch at Radioshack with two long leads. I installed the switch in a hidden place up in the dash. I then ran the leads through the firewall and connected them to both sides of the coil. When the switch was "on" the coil was shorted out and the car would crank all day and not start. This actually saved my car from a shopping mall car thief. I came out and there he was trying to start the car. When I offered to 'help him' he ran off.

The nice thing behind this was that since the battery was hooked up, the clock, etc was all working.

If you cannot short the coil, you can get a battery disconnect at an auto parts store. This is a key switch that goes between the negative terminal and the negative lead from the battery. I have on the BMW which I use to disconnect the battery when I will not be driving the car for a while. The downside is that the computer, clock, etc will not be getting juice.

Another trick is to remove the wire from the coil to the distributor (if this car has one) I used to do that with the 1957 Chevy until I got another key switch for that car.
