Car has plenty gas gets plenty of fire but still wont start...

Owner, You are speaking of a Northstar 4.6 L V-8; which has a reputation for failed cylinder head gaskets, especially when overheated, also has a lot of crank sensor failures, A Scan tool needs to be used to check data, look for an RPM Signal when cranking, Also, check for coolant contamination in the engine oil, compression test, and fuel pressure should be tested with a GUAGE, not by how far it squirts.
