Hi AJ Riekert, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? It could be a lot of things. You hear the fuel pump running but it won't turn over? Spray carb. cleaner in TB if it cranks...bad fuel pump. ignition coil, crank sensor, etc. need more info, like is the check engine light on? what is the codes the scanner is throwing?Hi AJ Riekert, I want to help you with your question, but I need more information from you.

Check all the wiring connections that you loosened or took off when you removed the head. something is loose or disconnected ,eg., ground wires .
Make sure you have spark at spark plugs whemn cranking ,and fuel pressure.
Did you try spraying starting-fluid in the intake, see if the engine runs for a little bit.
Compression to be anything above 100 psi will firean engine ,sometimes lower too.
It Could be A Number of things, Start by Checking for Vacuum Leaks at Intake manifold, Work your way OUT from there to the Various Vacuum LINES . Check FUEL DELIVERY Such as PRESSURE< FUEL FILTER, Fuel pressure REGULATOR All this Needs Checked
Are you sure its no spark? It could also be a bad fuel pump... have you done a check for spark? If you pull one of the plugs out and lay it on the engine block and turn the car over a few times you don't see spark, or it just doesn't fire when it cranks?
I suggest you perform this test. If you see spark I can almost guarnatee that its a fuel pump issue.
Try this test if the one above passes. Pull off the intake hose (big thick hose attached to the throttle body) and spray in some starting fluid. If it cranks and tries to run but then dies, that suggests that there is no fuel getting to the motor which is usually a bad fuel pump as relays and fuses usually don't burn out on their own. These two tests should narrow it down pretty significantly. Hope this helps! Good Luck!
