The ignition control for coils is integrated in the ignition control module on this vehicle. Testing is needed using a diagnostic tool to monitor performance components. Jump starting the vehicle is not necessary if it has ample battery power to crank the engine. Ignition timing needs to be proper, fuel delivery as you've apparently tested is present, not sure what "faint" spark is. The proper amount of air intake is required, and no anti-theft system influence should be present.
