No fuel pressure
Ok so I will purge the lines up to the shrader valve and any air that might be still in the sytem will be taken care of after a few days. Sounds good. Thanks
No waiting if you purge. Here's a post where I instructed the same thing, -

Ok fuel pump is in. Purge was successful and I have fuel to my injectors. That means my fuel pump was bad. Now the engine is cranking and not even attempting to fire. Im going to check and make sure there is power to the spark plugs but is there any special reset switch or something weird that I have to do to get this engine to come to life? I have tried spraying a little starting fluid into the throttle body and nothing happens.
ok there is power to the coils and power to the injectors. When I first sprayed a little starter fluid in it the motor studdered but only for a moment. Then no matter how much I sprayed in afterwards it wouldnt do anything.

Not sure if your pump was bad, -unless you did what I told yuh way back. I guess it doesn't matter now. Cycle the key 6 -9 times. DO NOT START, just cycle the key and pause for 5 seconds between cycling, since either your hard of hearing or your pump isn't charging the lines. Why did you replace the pump?
This is what happens when you don't follow instruction lol. Regardless, just do that EXACTLY first and we can go from there. I don't want to get to far ahead in one post as that may of been the problem.
Try it.

At this point you should see if the plugs are wet with fuel after cranking.
The driver side cam sensor times fuel injection.
If you had the cam drive chains off, the injection timing may be off if they did not get back on and in time.
This is the second thread where a motor was taken apart and did not get back togather correctly.
This other thread was one head was changed and the cam/ chain was not indexed correctly.
The side untrouched ran ok. the Other side was all but missing.
He was 'lucky' not to have had the valves hit the pistons on that bank.
If you have fuel present and know there is 'spark' not just power to the coils; it's the only possibility left since the motor did show signs of life..
Good luck.

Regardless, glad you got it figured out.
Damn we are on a roll for miscommunication... Yeah, I did the pre-check. I had to wait a few days for the pump so I went back and tested everything to make sure it was the fuel pump and not something else. Also thanks for the help.
So its been a little while...been super busy with school starting back up. Turns out the fuel pump was the culprit and so was an unplugged crank position sensor...thanks to my brother. Truck runs great and there are no issues whatsoever...thanks for the help again guys. I appreciate it.
