Bronco won't start
 

Engine 5.0 and year is 91. I'm not getting any fuel out from the rail where you simply press it down with a pin and nothing come out but I'm getting spark. I don't own a fuel pressure tester and it was running good before I changed the thermostat, flushed coolant out and aligned the distributor so I'm lost here and wanted to see if there's another way, thank you.
