Starting Problem

[blackgpz at rochester.rr.com]

Our GPZ's are particularly sensitive to battery and spark plug condition. My experience has been once a plug is fouled it must be replaced. Trying to clean it doesn't work in the GPZ. My experience has also been that when the battery is on the way out, it will have enough juice to crank the engine but it won't fire. Sounds exactly like your problem. You'll spend (waste) a lot of time checking everything in the ignition circuit, only to find a new battery cured the problem. I was one of them. After days of work, I installed a new battery and viola! I replace the battery every other year as a routine maintenance item and except for occasionally having to cycle the ignition switch, I've had no electrical problems of any kind since. YMMV and good luck.
