Will not start

How are you confirming it is getting fuel and spark?

I have taken the return line off and cranked it over, also I have a light that plugs into the coil and the coil wire. when I am cranking the engine over the light flashes constantly until I let go of key.

Okay, but that does not mean the fuel injectors are working or even powered up. Check the fuel injector fuse, the ECM fuse, then check if there is voltage available to the fuel injectors with the key on run/engine off then last if need be, check with a noid light if the fuel injectors pulse when cranking the engine over with the starter. If there is a check engine light on, check for codes if you have not found the problem yet and of course if this has a anti-theft system and a security or theft light is on, try a spare key or try to clean that key where the pellet is and try again.
Or a quick test shoot a few shots of starting fluid into the throttle opening and try to start the engine, If it starts and runs for a few seconds, then most likely it is a fuel problem and the ignition is working just fine.

Okay, I will give it a try. Thank you.

Okay, let me know if you run into any problems.

I have checked the injectors wires and I have current to them. I put a test light on them and turned engine over and light pulsates. Still nothing is happening.

try cleaning off all the sparks plugs and try again. if it does not start immediately after cleaning all the spark plugs, try a few shots of starting fluid and let me know what happens.
I am reading that in order to replace the water pump you had to remove the timing belt. Are you sure you got the timing belt back on correctly?
Here are those timing marks again.
