wow its very low readings,seems like well worn engine

you need to check for fuel and spark now

the fuel is running great and spark only less than 2000kms old.

Test for spark and fuel does not mean is fuel flowing in the rail and are your spark plugs new, it means, are the injectors firing and spraying fuel into the port, are you getting spark at the plug itself and in the correct firing order..

You should consider completing the wiring and wire up the cluster so you can see what the engine lamp is doing, putting the ECU into diagnostic mode may help you find the issue.

does the engine light go out after 3 seconds ?

take a photo of the inside of your ECU for me and post it here

The low compression may be due to fuel wash on the cylinder walls.( over cranking with no spark but injectors still firing fuel) Easy way to check this is oil seems.thinner than usuall or smelling like fuel.

Quick way to fix this problem is disconect injectors Remove spark plugs and add a teaspoon of oil in each cylinder this should seal the rings again. Put plugs back in and crank engine.

Most importantly find out why you have no spark if
you dont
