The violet wire should be powered only when the ignition switch is in the "start" position. The cycle ends when power is removed from the start circuit.

It sounds like you have an interruption in the "run" circuit (red/black wire), such that the timer "thinks" that the ignition switch has been cycled off and back on again, thereby restarting the timer sequence.
When you say the "start" position, you mean the glow position, right? This would be just before turning the key further clockwise to crank the engine? Once the engine is cranked and running the violet wire should no longer be receiving power?

Where is this "timer"? Is it part of the ignition key switch?
