Make sure battery has a full charge. If the battery is down because of testing, you can't test anything. The connector at your coil pack, four wires. One is voltage, goes hot with the key on, the other three are grounds, one ground for each coil. Use an led testlite between voltage terminal and one of the grounds, engine cranking, does the lite flash?
Any applicable trouble codes?
