2003 Subaru Outback Car does not start

Car does not start.

What is it doing? Is it cranking over and will not start or won't crank at all/nothing-your sure its not an anti theft deterrent device problem.

Yes it is cranking. I am not sure what is wrong. There is no spark on a spark plugs. I tried two different OBD 2 readers both gives the same link error to the computer.
Is there the way to check ECM?

Do below

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,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor camshaft and crankshaft sensors- Note: If it doesn't apply disregard it
