185psi of compression???

You got a snapping blue spark and the correct fuel pressure and injectors are pulsing-its time to check the valve and ignition timing

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/broken or jumped timing
belt/chain.
