Cranks but wont start

Hey I'm new to this group with a question about my 05 bursa. It's cranks but won't turn over. I've done a spark test but sosnt see any spark but I sprayed starter fluid in the throttle body and flames shot out of the exhaust pipe but still won't turn over. Compression teat showed 150 psi in 3 of the 4 but about 120 in the other so I put a little oil in the cyclinder and it jumpes up to over 170. I'm baffled as to what other stepa or test to run to figure this out. I thought about checking the timing to make sure its set right but haven't yet. What else would you do or recommend that I do

You need to check the fuel pressure and delivery from the injectors, check for signal at the injector connector plugs.
Also check for signal at all for coil connector plugs and spark at all 4 coils, with existingplugs, and if necessary, new plugs. You should see a fat blue spark at each coil/plug
As for the compression test you ran, recheck a few times to be absolutely sure that the cylinder that is low on comp. is actually low.
Then perform a leakdown test on that cylinder to ascertain where the compression is actually leaking from . . rings? valves? headgasket?
It's a laborious process but it needs to be done correctly, no shortcuts or assumptions.
Also, this is really important too, you need to hook up a jump pack or jumper leads with a fully charged battery to ensure fast cranking speed and voltage NOT dropping below 10v whilst cranking.
Good luck and let us know the results. :rolleyes:
