Cut wires on door - 1992 c1500

[62step]

I got a 1992 chevy silverado C1500 extended cab shortbed with a 5.7L 2wd from a friend of mine. It was sitting for about 10 years before I got it, the motor was stuck and I got it unstuck (I was able to spin it freely). Before he let it sit he was prepping it for his diy paint job, well when he took the doors off, he cut the wires for all the power switches.


I've tried to start this thing for about a week, cranking, has spark has fuel, just cranks, doors still off with wires cut. Should I put the doors on and wire it up and see if that does something?

I'm not sure if there is a security or system thing that will not let me start the truck due to the wires being cut.

I know that I will probably need a rebuild on the motor due to it being stuck, but just wanted to know about the wires being cut.

Thanks!
