'91 trooper 2.8L won't crank or turn over with new battery and starter. what up

What is your question?

crossed starter term., used starter fluid, changed neg. batt. cable, confirmed pos. has good connection. rebuilt starter, bought new battery, checked all fuses. what do I set my meter to for checking relays? can sensors or modules be the problem and which ones? got no accessories, lights, bells...nothing happens except a steam rolling growl and a few out-bursts of bad language.
