From top post:
"So the Fuel pump relay works.. it makes a good healthy sound when the key is turned on. When I disconnect the fuel line fuel squirts out all over!"

Don't be misled by the pump running when Key is turned on. That's not the same ECU control as required for cranking and running.

But it will instantly build enough pressure for the "squirts" you are seeing.

Try feeling the relay when you turn the Key on, so you'll know what it feels like when energized. Then feel it while you turn the key farther to crank it over. You should feel that same "click" again as the cranking begins.

If no click while cranking, that's a problem. But right now I can't imagine what part of the Timing Belt job could have gone sideways on you and cause a relay control problem.
