1997 Eclipse GST problems PLEASE HELP!?

The problem started when the car would have trouble starting sometimes. The car would have to be rocked a few times to get it to start. The other day, the car just wouldn't start at all. We got it to start intermittently, but nothing seems to be working. Replaced the starter, the battery, and the battery cables. When the starter is grounded, it clicks but no fuel pump. When the starter is not grounded, it doesn't click but the fuel pump starts. No idea what's wrong with it. Help!!
