SAAB 9000 wont Start 1994

I bought Saab 9000 that was said to have a "locked Engine" when I got the car home I inspected in and found no signs of a locked engine. So I bought a new battery and hooked it up. The car clicked every time I turned the ignition and on about the 15th try it turned over, but did not fire... every time I try it clicks 15-20 times than will turn over. If I keep the key turned and continue to turn the car over it will stop on its own after about 5-10 seconds. And than the process starts all over again. Just wondering if anyone had an idea of what it could be. Thanks
