No, cranking but not starting is a sign of a bad fuel pump. Clicking and not starting is a sign of a loose battery terminal, loose starter terminal, bad starter, or bad battery.
If you tried starting several times without success and turned the key off each time, then you might have flooded the engine which will cause symptoms like those of a bad battery- slow cranking, non-starting. If you don't turn the key off, then it won't spray another startup fuel charge. If you think you're flooded, do this: Key off, press and hold accelerator to the floor, turn key to start- no fuel will be sprayed- when the engine sputters or starts- let up on the accelerator. Now start normally if it's not running.
