I had a prolem like this one time a while back. what i did was got the wiring diagram and checked everything that was running through that 30 amp fuse. on the one i was working on it ended up being an injector wire pinched under the valve cover and it didnt short out till the car was driven til it warmed up and expanded after the valve cover gasket was changed. hope this helps!

A code 6 is an RPM missing signal. Your distributor coil circuit is open (or could be the coil).Check continuity with a volt meter.Check the blue/yel wire and the white one for cracks or broken,and if possible trace them to the computer for continuity. This malfuntion is a code 6 BUT car should start even so. Now to the injectors:check pulsating ground from computer,if not check wiring,if they are OK,try another computer.

Please see my tip at http://www.fixya.com/cars/r6223989-ignition_coil_doesn_t_spark . These are generic instructions--specific instructions are pasted below from Autozone.com. If you get stuck, please get back to me.
Use a test light to check for power to the coil on the black wire with a yellow stripe--see procedure below and other tests you can run. You will need a volt-ohm meter to run most of these tests.
The system used on 1990-95 Accords and 1989-95 fuel injected Preludes uses the distributor components to signal the engine computer. The ECU triggers the spark through the igniter unit and coil. This spark timing is controlled by the computer as an integrated function of the fuel management system. The distributor contains a crankshaft angle sensor and a No. 1 Cylinder Top Dead Center (TDC) sensor. Using these and other electrical inputs, the computer controls spark timing electrically.
