If engine compression is good -could be a fuel or spark problem. Do below to determine the cause
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

how do you know if the starter is bad without taking it out and testing it?

Short out the starter solenoid if it cranks the engine over the starter is doing its job
