The crank sensor's air gap is critical. New ones from the dealer have a thick paper spacer stuck on the end. Many aftermarket ones have a thin plastic rib molded to the end. If you reinstall a used one, you are to cut the remaining part of the rib off and use a new paper spacer.
A scanner will show the crankshaft position sensor and the camshaft position sensor as "no" or "present" during cranking. If either signal is missing, the Engine Computer won't turn on the automatic shutdown (ASD) relay. That relay sends current to the ignition coil pack, injectors, and fuel pump or pump relay. By far the most problems occur in the sensor circuits and you have no spark and no fuel. The pressure can be misleading because the ASD relay still turns on for one second when you turn on the ignition switch. That runs the pump for one second and gives the appearance of good fuel pressure.
If you removed the injectors and saw them spraying fuel during cranking, the ASD relay has to be turning on during cranking and there's no need to go looking for a sensor problem. Besides that sensor circuit, you only have the ignition and fuel systems. Both are responsible for relatively few problems but it sounds like spark is all that's missing. That leaves the coil pack and the wiring to it. I suppose the computer could be not firing the coils but it's rare for one circuit to fail and it would be even more unlikely for all three circuits to fail. I think I'd start by measuring the common 12 volt supply to the coil pack. If that is missing due to a broken wire or corroded connector pin, all three coils will be dead. That should be the dark green / orange wire. You can use a stretched out paper clip as a probe to go through the rubber weather pack seal next to the wire. You should see 12 volts on that wire for one second after turning on the ignition switch. If you do, the wire is okay. If you do have it for one second but it doesn't come back during cranking, you have a sensor problem, and the injectors can't work either because they're on that same circuit.
