I have a 1995 Buick LaSabre, it is in pretty good condition with a good, one year old battery. My problem is the car will intermittently refuse to start. When this occurs the electric fans on the radiator run. The engine will crank over vigorously but the engine will not fire up. Then, after 5 or 15 minutes of leaving the ignition switch in the on position the fans will quit running and the engine will fire up immediately and run normally. I have wiggled all the wires and connectors I can find and can neither make this happen or unhappen. What gives? Any ideas out there?

PS: I tested the spark with a powered Timing Light. I tested two or three spark plug wires while I was cranking the engine and the timing light flashed on and off, but the engine still wouldn't start.
