please help! changed head gasket, wont start

Blown headgasket on my 97 LHS. I changed it myself but car wont start. I marked the timing belt and am sure i put it on correctly. Any help is welcomed.

When You Changed Your Head Gasket Did You Remove The Fuse For The F/injection If So Put It Back Check All Your Sensor Connections Fuel Pressure /spark/compression On That Head If You Did It Correctly It Will Start
