1992 Subaru Legacy 4 cyl All Wheel Drive Automatic

Set crankcase pulley along with the 2 other pulleys to TDC. When manually turning crankcase pulley bolt with a socket wrench, or turning over engine, the crankcase pully TDC mark is opposite the other two pulleys timing marks. When turning again for a short while they line up again. Is this normal? Crankcase pulley is ok and not slipping. Also car just turns over but doesn't start.

Sounds like the valve timing is set-its takes 720degs to complete the 4cycle stroke

Put the engine no.1 piston on its compression stroke/TDC -line all the sprockets then put belt/chain on.

Even if the valve and ignition timing is off it should have spark and fuel-do below to determine what's missing.

If the engine's condition is in tip top shape-do below to determine if its fuel or spark problem that's if its cranking over and refuses to start

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not 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 problem, check the fuel pressure to rule out the 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, distributor pick-up coil, ignition control module, cam and crank sensors-

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
