No bueno
I just got done putting my 2011 5.7 hemi back in the ram after a cam upgrade. Most of the wiring is hooked up, ( except headlights, blinkers,etc.) I deleted the mds system and one ug is empty because of that. Now, it won't start, not even turn over. Could it be because of that plug? Another thing, I broke what I thought was the oil sending unit , broke the plug off. Could that have been the crank sensor? Would that have caused my problems?

Hello
I would definitely double check your wiring hardness connections. The crank position sensor uses a 3 wire connector with the following colors PK/YL (5VRef), BR/LB (Signal), DB/DG (Ground) . The oil pressure sensor also uses a 3 wire connector using the following colors PK/YL (5VRef), VT/GY (Signal), DB/DG (Ground).
Notice only the signal wires are different colors.
Have you tested for spark or fuel?
If you have a scan tool does the RPM PID show a value while cranking?

I might have the crank sensor on the wrong plug, but, will it cause a security issue?
and.....my Innova scanner won't connect with the truck for some reason. That's why I can't see if there's a reading during crank.

A scan tool not being able to communicate with the PCM is a big clue. With the Key On does the MIL (aka check engine light) illuminate during the bulb check? If not, the PCM may not have power for some reason.
Regarding the crank sensor. The engine can't run without that signal.
