I'd have to make sure the battery has a full charge and the battery connections are clean and tight on both ends. If you use a digital voltmeter leads across the battery posts, everything turned off, the generic spec for a full charge is 12.6 volts. With the leads still hooked up, have a helper turn the key to crank, while you watch the meter reading, it shouldn't drop below 9 volts, some specs say it should drop below 10 volts. A national brand autostore should be able to load test the battery for you and charge if necessary.
The starter solenoid S terminal, purple wire, should be hot with the key in the crank position? If it isn't, backtrack that circuit. It comes from the ignition switch to tranny range sensor to starter solenoid.
