Need Help with 02 525i startup

I just replaced head gasket on a 2002 BMW 525i. This the 5th 5 series I have done in the past 4 years so I think I know what I am doing. This is the first one that does not start after I am done. It turns over and the engine has good power. I did compression test on #1 and registered 100 PSI. The spark plugs get plenty of gas when I open up. My suspicious is no spark, crankshaft position sensor or I messed up the timing on this one. With the ignition on I get good 12.7 volts to the wires going to the coils.

Please help.

I would start with the ignition coils. they seem easy to overlook when reconnecting things.

Any stored codes? Compression pressure is low. S/b 150 +/-. Out of time?

No codes at all and will probaly not register any codes until the engine starts up. Prior to the head gasket job the engine ran FINE but lots of steam came out of the tail pipe. Would incorrect timing cause low compressions? I will test compression on the other cylinders tomorrow.
