93 Si Won't Start???

Well me and my girlfriend bought a 93 Si for dirt cheap. The car is clean though, but it won't start. It has electrical power, I looked at everything to make sure like distributor, spark plugs, plug wires, and I'm still confused. I even used the Haynes manual to help me out if I missed anything. I even relpaced the starter with a DX starter, thinking it might be the starter and it still doesn't crank. What else could be the problem. :confused:

check the grounds and make sure the battery is good, because the battery is directly hooked up to the starter, so either the battery is no good or its a ground not hooked up, liek follow the battery ground and make sure its bolted to the chassis

did the car run when you first bought it?

it could also be the ignition, like the key ignition. i would try get a remote starter and try do that and if it starts u know something is wrong between the ignition and the battery
