From 12 Volts to 3 Volts with the turn of the key.-Please Help!
my 94 hatch wont start. When I turn the key to crank position the voltage drops from 12v to 3v. Im guessing there is a short somewhere.
The fuel pump does NOT turn on when key is ON since problem started.
I checked all my fuses in cabin and under hood.
I replaced the ignition harness and switch.-same problem.
I then swapped out the ingnition relay.-same problem.
My local honda dealer suggested to start unplugging parts so I unplugged distributor, airbags, fuel pump to try to narrow down the huge current draw. NO LUCK.
This happened a month or so ago but then started working again.-What the hell?
I previously had the starter and battery tested thinking it was the prob. Both tested fine.
ANY SUGGESTIONS SHORT OF ROLLING IT OFF A CLIFF WOULD HELP!

When the ignition is in the 'run' position do things work (like the lights, turn signals, radio, etc.)? It sounds like your battery is dead even though they said it tested good. What happens when it is in the crank position besides the voltage dropping to 3 volts? If you have a good battery and you turn the key to the crank position and it won't turn over and the battery voltage drops to three volts I guarantee you will see smoke.
