Swapped engines,won't start...

Used all the 03 sensors/wiring harnesses?
Crank/cam sensors plugged in correctly?
Checked all the pins in the bale connectors and made sure they arent pushed in, not making contact?
Are you getting any codes?

Used the 03 ECM/TCM/FICM, too? Cam/crank connectors can be accidentally swapped, so if you have a crank/cam code...look there.
Try to list whatever codes you can. It'll help us a lot. Right now, its just a shot in the dark.

I don't think the engine will fire if there's a vats issue but could be wrong. With the key on engine off does the security light on the dash go off after a few seconds? What does the fuel rail pressure desired vs actual do when this happens?

Since the truck was an 03, and the OP stated all the original ECM, TCM, etc modules remained in place as the 02 engine was swapped in, I'm not thinking VATS since that normally only causes trouble (start, then die like James said) when the ECM and BCM aren't properly paired.
OP, please provide the DTC codes which would give us a better place to start helping.

If you kept the original ecm with the truck then the vats, anti-theft, should NOT be an issue.
If, on the engine you installed, you installed the engine harness or the cam &crank sensors, you may have those transposed. The sensors OR the connectors. Those need to be correct for the engine to run. AND it’s possible to mix theses up. AND it will cause this issue.

I read your post again, looks like you installed the engine harness, as the 02 one is different. In the process of installing the 03 harness you plugged in the cam and crank sensor, or you should have. Check those connections at the cam and crank sensor. Your issue is there. No doubt.
They’re either not connected or transposed. Or the sensors are in the wrong position.

The harness from the 02 engine was used, everything plugged in. We are getting 100+ codes mostly transmission related which I feel are from the old transmission. Here are a few codes, u1000,B0105, on the powertrain system I've got 50 codes on the transmission and 50 codes on the engine. Where are the crank and cam sensors located?
you need to start by putting the correct 03 harness on the engine. thats part of your issue. lots of things changed from 02 to 03 electrically.
good for you and glad its running.
the lack of detail in these posts and lack of understand about what we are talking about makes this very hard for us to do much over text. at the end of the day, we dont know what you did, touched or if what you are saying is exactly whatyou are interpeting as to what is done. in the end, if you figured it out, thats all that matters!
