Crank no start after replacing head gasket valve cover

[spartan00j]

I really need help. I have a 97 BMW z3. I had recently replaced my head gasket valve cover. An after I got a crank no-start situation. I replace the fuel pump/camshaft position sense/Rear 02 senor/spark plug and ignition coils/fuel filter/replaced the gas cap/Replaced fuel pump relay/ It has a new battery. It still will not start.
Here are my codes:
P0340
P0420
P1188
P0442
P0170

Thanks,

Thanks,

1. Does it have spark?
2. Is it getting fuel?
3. How is the compression?
4. Is the timing correct?
