Re: FIXED: Code 19, crank no start
Did the same thing to my ignition switch, that I did to "fix" the horn, kill, and turn-signal switches... I bathed it in silicon spray lubricant and repeatedly operated it. (disconnect the battery negative so you can rapidly key on/off without screwing with the ECU) Initially its drain was clogged with old powdered graphite lubricant but all the spray cleared it. Clearing all that powdered graphite lubricant made the key very difficult turn-on so I fetched a fresh key and destroyed the old copy. Then I added a *tiny* bit of powdered graphite back. (TIP: always copy your original key and store the original away - do NOT keep using the original key - use only as a master for making copies)
I put the word "fix" in quotes because I've had to periodically repeat with turn signal switch. This last time I treated it, I unscrewed the halves of the box for complete/direct access, which has proven to be more effective thus far. Can't really do that with the ignition switch.
