I have a 99 zx2 and am having starting problems. I just installed a new fuel filter and the problem is still there. If I leave the car set for an hour or longer it won't start. It just keeps cranking and cranking. If I cycle the key switch three times it will start right up. I can hear the pump run every time I turn the key switch. Any Ideas what the problem might be? when it starts it runs real nice.
